New OSS Trader – Lucky7moto

We are pleased to welcome Lucky7moto as an OSS Trader, with a discount available for OSS as well as a fantastic prize to give away too!

Lucky7moto are well known for building cool bikes, several of which have featured in magazines around the world. Their ‘no fucks given’ approach has always been fun to see, take a look at their T-shirts! They do it because they want to, not because they have to.

As well as building cool bikes for themselves and others with deep pockets (check out the Katana or ET they built), Lucky7moto also sell specialist parts.

New bike builds in the making include a GSXR1100 Slabside for a customer and a GSXR Slingshot that will become something endurance based. All builds result in some bespoke specialist parts being made and these are then offered for sale to you.

Today their most commonly requested item is the seat re-covering service. Steve the founding member, is a time served upholsterer by trade spending years in the Aston Martin interiors factory. Using only the best materials like high-grade leather or the latest waterproof Alcantara to the best textured vinyl, Lucky7moto seats can be found on some of the best builds on the planet. Racefit can attest to that. Lucky7 seats are on all of their builds. Steve has partnered with Jay who is an active member here on OSS.

Whether it’s a GSX1100 Katana, Bandit, GSXR (or any other bike including one off specials) these guys can (re)cover it transforming the look of the bike. Just don’t ask them for embossing or bright blue stitched logos, that’s not what they do.

Current bike parts on offer are GSX1100 and Katana oil catch tanks, under trays, swing arm spacers to allow later model swing arms to be used and shock mounts to allow newer style mono shock arms to run twin shocks. Lucky7moto will also supply you with a Racefit Legend system if you ask nicely 🙂

The newest product to come out of the workshop is a stunning hand beaten aluminium tank for the GSXR750 Slabside. It’s internally baffled, much lighter than stock and a real thing of beauty. These are a limited run so be quick to get some exotica. Other limited run, hand made aluminium tanks are on the horizon with GSXR Slingshot and Katana tanks being talked about.

If you can’t stretch to a fuel tank then Lucky7moto offer some very cool T-shirts and stickers for sale too. OSS members will receive a 10% discount.

To celebrate their new OSS Trader status, they are offering as a competition prize a re-cover for your bike seat OR if you are lucky enough to be a Katana or GSX1100 owner – an oil catch tank OR undertray set. Basically one winner, one prize.

For details of how get your OSS discount and to enter the competition, see the article in our Traders section here. Please note that you need a 50+ post count on the OSS forum to take part.

Bike of the Month June 2017

Build it, run it, break it, fix it then repeat. The life of a drag racer can easily be likened to that of a drug addict. They spend all of their available cash and time working towards their next fix, even if it means ignoring the trivial things like food, clothing and sleep. The principle difference is that while a drug addict wants the hit to last longer, the drag racer does all that they can to shorten the experience. I’m reliably informed that once you’ve tried it, you either love it or you’re wrong.

Our bike of the month for June goes to Gary Hester AKA et1170. Gary has been evolving and racing this bike since he bought it nearly 7 years ago. Starting life as an 1100ET the bike now sports Katana styled bodywork. Gary was one of our first Winged Hammers and I like to think Hanma-Shin has had a hand in his results this year.

What I love about this bike and Gary’s story is that he has clearly never had serious money to throw at it. His success is a steady one. Carefully building on the previous years results with the parts that he could get. There are no turbos, no nitrous, no mega bucks cylinder head work- just oldskool, DIY air-cooled engine tuning in a shed. That, said if you read Gary’s thread you get the sense that Gary’s addiction will inevitably lead to forced induction and more…

Congratulations Gary you are June’s Bike of the Month.

Bike of the month January 2017

 

botm-january-2017A stylish beast of burden.

Style, we all want it….don’t we? but at what cost?

The thing about developing your own style is it takes time and effort…and a total disregard for excuses. An idea that you feed with whatever it needs and 99% of the feedback is negative…or a positive negative. The time and effort spent on the various ways of how not to do it is far from wasted.

More failures than success, but once you hit that sweet spot you make it look so effortless and flowing….but then comes the crux as the audience offers praise and, undoubtedly critique, your mindset has changed….more, more, more.

I have no idea how many times Blower1 failed to succeed in his style, but style he has. Congratulations on bike of the month.

It’s not important what you think but how you think, the mind is a beast….feed it in anyway you can.

Bike of the month December 2016

 

bike-of-the-month-december-2016Less is more, more or less…

There can’t be too many occasions when its perfectly acceptable to replace the mighty heart of an EFE with something….erm…well, a bit less EFE-ish

The EFE is a legend in OSS  folklore and a brute in stature, from the humongously sized (and priced) headlamp, its no nonsense alpha bodywork  and its squared off arse. You don’t mistake an EFE for anything else or indeed anything less…

or do you?…say without its monstrous 16valve atlas stone?

An idiom wriggling inside a can that’s rattling inside Pandora’s box, a Russian doll painted as a biker…. we could , or more accurately, those follically endowed, could split hairs and possibly a pint over such a premise… I guess it’d be prevalent to ask someone so old-kool and oldskool they probably had a highway hi-fi phonograph in their race van…

I guess one reason could be when N/A is not enough….I’d  be well happy to have such a beast of a conundrum.

Congratulations Clive AKA Duckndive, you’re bike of the month.

We travel not to escape life, but for life not to escape us.

711-in-the-sunWhat comes to my mind when someone mentions a motorcycle road trip around Europe? A large capacity sports tourer with hard luggage and a gel seat? Perhaps it’s an adventure bike with unlimited luggage capacity and the finest Gortex multilayer touring gear?

This story is about a motorcycle road trip that is the antithesis of what you might normally associate with motorcycle touring. In contrast to the norm, this story is about toughing it out, without compromise, on a two wheeled, air-cooled weapon of choice.  This story is about an almost Zen like minimalism all wrapped up in a “fuck you” sense of style. The bike and the rider are motorcycle touring nonetheless, because nobody told them they shouldn’t or couldn’t, and if they had,  I don’t think they would have been heard over the sound of one Suzuki’s finest engines being piped through a titanium Racefit growler.

mental

It all starts with a bike you would not normally associate with any kind of long range two wheeled odyssey. A 1230cc EFE powered Suzuki  ET special with a unique, tweaked and braced bare steel frame. It has no room for panniers. It has rear set foot pegs, a high level sub-frame and a single seat unit that comprises of little more than a thin layer of high -density seat foam.

The choice of equipment for the camping tour is both careful and clever. When you can’t carry very much you must choose carefully.

a-house

The choice of clothing consists of one pair of lace up boots, a set of one piece leathers from the 1970’s and a Simpson helmet. Not everyone’s choice of riding gear for such a long trip but now you might be beginning to understand what made this trip so interesting to me.

gear-on-the-bed

Welcome to the strange ways of frame building guru and OSS stalwart Alan (Strangewayz) Caven.  Alan called this trip Air-cooled, steel framed Anarchy! I think the trip sums up the uncompromising, meticulous, unique, creative and thoroughly considered approach that Mr Stragewayz brings to most things that he does.

14100380_1459524017407675_1274946120798466110_n

I had followed Alan’s trip over the summer through social media updates and I loved every instalment. There was very little narrative in his updates, mostly just pictures and one-liners but despite that the whole idea really appealed to me so I asked Alan if I could stitch it all together and get some background behind his motives for the trip. Here’s what he told me:

I went through a phase of not finishing any of my own builds due to always working on other people’s stuff, along the way I got tagged by a few people as falling into the category of enjoying building a bike more than actually riding it.

Nothing could be further from the truth; I don’t actually see the point in building something if it isn’t going to get some proper use. It’s the ultimate test of workmanship, seeing if the design, choice of components and execution were good enough.

Some people live for the dragstrip, track days or weekend ride outs… For me it’s all about a road trip, which has to be overseas and on something home built because that combination makes things edgier, takes you out of daily life home country comfort zones, tests both the bike and yourself physically and mentally (I broke both my elbows, right wrist and left ankle in a crash years ago so have a few war wounds to deal with).

I nailed my colours to the mast years ago – Air-cooled – Steel framed – Muscle bikes! Un-faired and loud is the way to roll.

Those of us that know Alan know that his unique take on Suzuki’s GSX 1100 ET was built as tribute to his late wife, who he tragically lost to cancer back in 2010.  Alan lost his last  remaining link to his wife when, not long ago, he also lost their dog Ozzy.  Alan explained that the bike and the trip were an important part of his climb out a pretty dark place.

gsx-tank

Whilst I built the 711 out of 7-Nov Rip Mrs Strangewayz with the intent to hit European streets with it, the real catalyst for this actual trip was when I also lost Ozzy – my Dobermann. The last link with my wife,as he’d been ours. He got me through some tough times he was always there for me. In that moment life was pretty shit, my whole world had gone and life didn’t actually make much sense – what was the point of it all if that was what was served up? I knew needed something positive to concentrate on.

The Provisional MotoGP calendar for 2016 came out with Austria GP & Czech Republic on consecutive weekends; that was it! I knew that by planning to travel minimal and mostly camp it would occupy my mind with how to actually do that. The easy route would be to leave mid-week and roll from Germany straight into Austria…. but that was too easy !!

Heard about Tavullia (Rossi’s home town) seemed a cool place, the man had a bar and pizza place so hey rock up over the alps and drop down into Italy before heading back up to Austria.

I just need an excuse to go and then join the dots up, I used (road) racing but as you can see the journey is more important than the destination, as is what you choose to do the trip on (bike).

The Icing on the cake was that the dates would work to end up back in the Isle of Man for the Classic TT Races. Game on!

I knew this was going to be a busy year because I was also going to the NW200 Road Races mid-May and the TT Races start of June.

Whilst I had some serious reasons for planning the trip, the trip itself was an adventure with a lot of spontaneous stuff going on.

This was how the actual route ended up :

Sat Day 1             Northampton to Bastogne in Belgium

Sun Day 2            Bastogne to Lake Constance (Germany)

Mon Day 3          Lake Constance to Riva Del Garda (Lake Garda – Italy)

Tue Day 4            Riva Del Garda to Tavullia (Rimini near San Marino)

Wed Day 5          Tavullia to Spielburg (Redbull Ring – Austria)

Thur – Fri – Sat – Sun all Moto GP

Mon Day 10        Spielburg to Linz (Austria – OSS Greg Sochor)

Tue Day 11          Linz to Brno (Czech Repb) Chance of a pit pass J

Wed Day 12        Brno to Prague (Czech Repb) no pit pass lol..

Thur Day 13        Prague to Brno (loose keys….)

Fri – Sat – Sun     all Moto GP

Mon Day 17        Brno to Nuremburg (Germany)

Tue Day 18          Nuremburg to Etalle (Belgium)

Wed Day 19        Etalle to Northampton (England !)

Thur Day 20        Northampton to Isle of Man

Fri – Sat – Sun – Mon all Classic TT Races

Tue Day 25          Isle of Man to Northampton

Wed                      Back to work….

After speaking to Alan I realised the best way to recount this tale was in the way that I had first experienced it on social media, so I have chosen my favourite updates he made during the trip  below and embedded any words as he used at the time.

 

Early start this morning 4am ish… Neighbours love the sound of a Racefit exhaust clearing it’s throat..

160 miles later it was ferry time, off & the down the road a bit now. Just had a broken English sign language ‘you look like the Stig’ moment…….

Long time since I did a 400 miler, good to be back t it.First night stop over, clues on the bar.

Lol worst camping pitch I ever had, lucky I got a 3/4 Thermarest + Jungle Juice & a Balaclava to survive the midges by Lake Constance as I put tent up in the dark last night. Strangewayz 1 – Midges 0

Think I’m in a different world… The locals are going to love the sound of the 711 clearing it’s throat Racefit style…

 

 

Rocking late 70’s Dainese one piece, genuine retro race gearI scored off Italian eBay last year. Just these & a pair of shorts, non armoured so not as bulky as modern stuff. Looks cool as on the 711

Kriega Hydro 3, wouldn’t be without it. I buy a 1tr bottle of water each day & throw it in. Leaves space for other easy grab gear & so light it’s feels like wearing nothing. Has bladder pocket + 1 other zipped side pocket & the elastic string on the back. The mouth piece is easy to use whilst riding.

Wasn’t sure but having worn them fucking brilliant, these are the ‘Adventure’ ones, they also do Cruiser or Sport. Have computer designed pads so yeah like posh cycling shorts.

Right I’ve put the riding gear to bed, I got me a table booked at Rossi’s Bar & Pizzeria tonight

Built in a shed to noise up Europe haha. Back mid 80’s when I was on LC’s & RG500 always went to Silverstone & rode over to the Dutch TT at Assen on the Gamma when 18 or 19. Back then always wanted to take some weeks off work to follow the GP circus, everything was more raw & less polished then Schwantz, Lawson, Rainey… Didn’t get to do it, routine life took over, roll the years on & yeah a bad roll of the dice but hey building the 711 was about looking forward & whilst Mrs S (rip) can’t do this shite no reason I can’t & with a big smile on my face

If I set that up in England it would be so fake !! Love the different cultures

Random prep !

Side of the road rain gear & visor change, car travel this isn’t haha… Strangewayz keeping it real !

US Urban battle Goretex, gaiters & Red Wing boots – oh yeah & no quick shifter lol

Wrong sport but if your into VW’s this is the famous She’ll garage (now Eri) outside Velden which is ‘The’ place to hangout at the annual Worthersee show. I will be back out this was in my Mk1 Golf in a few years when it’s done. My stupid idea was to get here then find somewhere to wild camp. At silly am it was hard trying to find anywhere as built up with resorts & posh hotels. In the end pushed 100km onto the Red Bull Ring running low on fuel (all shut), IPhone battery (Google maps) & energy. But I did it & I love my bike, 711 was awesome, better than me !!

Definitely regard it as a badge of honour when, so far I am the only motorcycle on the campsite for a bike race ! Especially when I had to move my tent this morning being considered in the way of the the blue awning the couple are putting up who just arrived this morning in their van from up the road (Austria). Hey who knows maybe they will share their beer with me later hahahah….

Road trip shite Austria MotoGP
Not really on the piss, that’s when riding solo parked up for a few days is hardest. English speakers thin on the ground but I’m in a good place.
Side of a mountain, village part of the track, cool shit, locals love the visitors, bit Euro beat/pop 24/7 sausage feast – why the fuck do you want to dance on a table with your mate – that’s for girls to show off haha… but didn’t do this to feel like I was down the local.
General admission ticket (grass) but shite, Isle of Man has spoiled me, but found a good spot with the boys leaving rubber. Dovi & the Maniac at each other all day, Vin what a boy! Cru at times top Honda. MotoGP app excellent with live sector times & a track graphic showing rider positions.
Good times, memories lots, ride your bike & go do shit.

It’s all about Suzuki, rockin’ Rizzla T today

T shirt drying, would make a good paint job…

Haha love beer time lapse memories, this is the main ‘bar/club’ in the village – late last night they were playing a Euro Beat track “Mr Brown, Mr Brown, will make you smile”. Pissed myself, would sure put a smile on my face .. hello luv

Ahh tent life, big grin, chilling out, road tripping again in the morning, good times rolling.

Ready to roll, still got the Tavullia cardboard sign to strap somewhere 🙂 Heading north to Czech Repb for their MotoGP race. Stopping off today to see Oldschool Suzuki Greg Sochor in Linz some 200km away. Prague on Weds then back to Brno Thurs ready for the racing. Austria MotoGP was awesome event 215,000 people over the 3 days. Great racing, atmosphere & the sun came out to play.

Fuck yes, tent up at Brno circuit, beer going down hatch.very pretty bar maid, could get to like this haha !!

Hanging around feeling lucky…

Czech MotoGP pit pass gig didn’t fall into place, hung around for 2 hours & can you believe as I was riding out along the back lanes the wagon rolled past in a group of 3 ! Turned round asap but by the time I caught them up the guys were already through the barrier. Had a cool time hanging out & wasn’t meant to be. On way to Prague & seriously the main motorway from Brno up is the worst piece of shit road I’ve been on. Bone shaker of a road with a nasty split/crack between lanes 1 & 2. Pulled over for a coffee to check out other routes ! Still smiling though 🙂

 

85km away form Prague river campsite, needed chocolate so hey park under 3 cameras. Girl too right was seriously sexy….

 

The Girls are Pretty & the Roads are Shitty. Czech roads are the worst piece of crap I’ve been on, might be different in ya cars guys but on a bike you get hammered, Garmin satnav plastic mount just broke because of it, will be on the hunt for cable ties & duct tape 🙂

Ffs we have lost key, Hotwire plan… seriously no photo setup, but still smiling !

Look it’s all about priorities, sweat talking the bar maid to get…… the Suzuki pics from her calendar haha go Vin !!!

Hmm describe Al in a pic ! Yeah beers going down well…….

Seriously impressed the Dunlop Q3 is keeping it’s profile, had to do some serious straight line miles in 30 deg air temps with all the gear on the back & it hasn’t got a shite flat section yet. Too many UK cars showing up around Brno, keep it on 2 wheels guys !!!

After yesterday’s Hotwire after loosing keys on trip 5km away to local atm…. got 3 days parked up as track is walking distance. Re checked my spares kit & lucky boy I did pack a few goodies, should be able to do something ok to last the 1500km trip home 🙂

Having a shite time as you can see whoo hooo

Err so it’s not 8am & sat by the side of the road drinking beer with a dude from Panama also called Alan lol either that or it’s all a weird dream. I only stopped for an espresso because the girl was pretty but the machine wasn’t warmed up……….

Brno MotoGP !

Suzuki out spotting, MotoGP Fp3

 

Cup say “100% energie” hope it works 🙂

Agh the moment the sugar rush hit whoo hooo caking my way through Germany….

Pffff not impressed my Oberon mirror has fallen apart on me again ffs. I like the gear but for what it cost I don’t expect to have to hold it up on my knuckles whilst waiting for a foreign motorway services to pull over & take if off. Fail 🙁

Hmmm choices choices ok both !!

Chasing the sat nav down, got a good number on it that gets me on the ferry. Fuel stops only, cake later !

 

Still riding !! Stoked about my next stop if the guys are there…..

That’s as good as it got, the guys had closed down a while back – just a trailer outside a Kawasaki shop. Waltz still makes stuff under the name of Walzwerks but too much of a wild goose chase to hunt him out…

 

 

 

Time to roll again

Tent world, waiting for the morning, want to go out & ride

Sitting at the Creg taking in all the wonderful sounds from the different classes out practicing. Fantastic views in the background which is why I didn’t bother taking a picture of the pub !! Awesome to see 250cc two strokes back racing on the island with their own class.

Ready to roll again, off to watch the Superbike Race & then will be on the ferry home…..

Hard life, Raybans on, Superbikes almost ready to go, c’mon Suzuki !!!!

Still going strong – Aircooled forever !

 

 

 

 

 

Any day I ride the 711 is a good day just some are sadder than others.

So if you’re reading this and you still don’t understand and or admire the sheer insane and inspirational brilliance of  this road trip then you are probably on the wrong website. Alan, OSS salutes you sir. Here’s to building  them, riding them , and smugly enjoying what you have carved out using your hands, your ingenuity and your imagination and here’s to never letting anyone tell you that you can’t.

This is Alan’s story, so it’s only right that he should get the last word.

What an awesome bike! Still riding it every day to work, need to pull it off road soon as brake discs, pads, rear sprocket almost shot – had to put some winter tyres on (Michelin Pilot Road 4’s) as the Dunlop q3’s which I had on for the trip & did everything I wanted but won’t grip below 5 degrees.

Trailer Queen… Only used when the sun’s out…

Bike of the month November 2016

botm-november-2016

Ticking all the boxes…

BOTM first of all must fit within the rules, after that I haven’t picked bikes I’d like to own, just builds that have a certain ‘je ne sais quoi’..be that in the amount of info the member has shared on the site, through to ‘I can’t believe that’s the same pile o’ shyte from the first post’.

A bike that has evolved to Tom’s exacting standards (these can sometimes be winced at but never shunned, Tom has not got all his frequent flyer saddle miles on luck alone) and as I type this he is still awaiting a part to complete the next episode, which I’m sure is not the final chapter.

I’d ask any newcomers to the site wondering what OSS is all about to firstly RTFR, then read Havocs AnerchEZ RatRod thread. Pretty is as pretty does….. congratulations Havoc on BOTM, the evolution will not be televised.

GSX-R engine mounts for a GSX Frame

Enginemounts1

Below are drawings of engine mounts to fit an early air-cooled GSX (round frame tubes) or EFE (square frame tubes) with a GSX-R engine. Both place the engine in the middle which is aesthetically best but may cause some problems with the exhaust headers interfering with the frame downtubes, which can be solved by using spacers or modifying the headers if necessary.

Engine mounts for a GSX1100EFE (GS1150) to take a GSX-R engine.
By “GJG”

Below are drawings from the engine mounts, as I used them a few years back. I built at least two EFE’s using these plates. They mount the engine pretty straightforward, like in the Katana I send you pics from a few months back. I also included the cutting contours in .dxf format, that could straight be fed into a laser.

Parts description:
PL-105 and 106: Take front rubber engine mount, and lower below crank. Need shims or bushes to compensate for offset.

PL-107 and 108: These should be welded in with the engine or cases in place, mounted with the previous mentioned plates. PL-108 is a bit long, and could do with a brace, taking sideward loads to the cross tube from the shock. The stock plate should be removed. The lower cross tube in the frame will need some cleaning up and removing of the stock lower rear plates, before taking PL-107.

PL-110 and 111: These make the removable, welded upper rear engine mount taking loads to the stock bolt holes/bushings welded into the side of the frame.

Making your GSX frame stiffer

Making your GSX frame stiffer
Written by Mr.7/11, inspired on earlier work done by Tony Foale, Arnout and Tinus.

It may be well known to anybody that creating a stiff frame has to do with connecting the headstock to the swingarm pivot as direct as possible, which is what modern “Deltabox” frame designs do. So the best possible solution is to weld f*cking huge bars from the headstock directly to the swingarm pivots. There is just one problem with that… there’s a huge mother of an air-cooled engine in between that hasn’t followed any diet …ever.

frameremovals
To keep the weight down we remove some before adding any.

And besides she’s so beautifully shaped that we wouldn’t want anything hiding those luscious curves from full view now would we? So we’ll have to resort to beefing up the frame we have as well as possible so the front wheel will keep in line with the rear during heavy braking/acceleration as well as big bumps in the road.

The GSX frame is of the “cradle” type which means the main frame tubes are routed above and below the engine. We haven’t got many options for reinforcing the lower cradle as there are exhaust pipes, oil cooler lines and the oil sump between them and we don’t want to create problems while performing regular maintenance.
So we leave it alone with it’s primary task to keep the engine in place concentrate on the part of the frame that runs above the engine.

Take a look at the picture below.
The weak point of the frame is the green section between the headstock (yellow) and the swingarm pivot area (blue). If you look at early GSX-R frame designs you see that on race bikes they have allways tried to beef up that area with additional plates. There’s also a rumour this is what Yoshimura used to do with their GSX superbikes.  Suzuki have allready paid lots of attention into making the headstock as stiff as possible so the effect of additional bracing here will be minimal. If you intend too keep the standard airbox and the battery in it’s original place then options for bracing around the swingarm pivot will be minimal too. So if you would like ot improve the stiffness of your old dinosaur I’d make modification C. first, and consider dumping the airbox in favor of separate K&N filters to be able to add D. and E. When you’re at it you might as well go along and add braces A. and B. but I don’t consider them to be essential.

Be warned that reinforcement C. can hit the inside of the tank if you make it too big and will also make it hard to find enough space for the air filters! You should make all reinforcements from cardboard first anyway to check that they don’t interfere with anything.

framemods

A. these tubes support the headstock against torsional movement. The plates B. support the frame tubes to prevent them from bending due to the load created by tubes A.

The cross-bars D. stiffen the area above the swingarm pivots. The tube connecting both sided is placed at the same height as the engine mounts to keep the engine in place under acceleration. If we replace the cross-bars with a pyramid D1. we add even more stiffness to that area and prevent the swingarm pivots from moving back and forth in addition to up and down. It may look a bit awkward and I question if it adds anything as you must not underestimate the strength and function of the rear subframe.
This might be why Yoshimura adds gussets to the subframe on the Katana 1135R, but they have also changed position of the shock mounts considerably. They probably did this because they use a very short swingarm to decrease the wheelbase and so improve steering into corners and if they kept the original mounting point the shock would be too upright making them too hard.

framebraceexample
Examples of frame braces on the Yoshimura Katana 1135R

The connecting rectangular tubes E. help to distribute loads from the swingarm pivots to the rear of the frame, as well as providing a mounting point for the rear brake amongst other things.

F. There’s very little room to triangulate the space in front of the cylinders because of the exhaust pipes but it is possible. You may need to dent the tubes a little to make them clear the exhaust pipes but this is better than making the V smaller. Tightening the two center exhaust clamps will prove difficult too.

Gussets © Tony Foale

Now that the headstock and swingarm pivot areas are beefed up the connecting tubes are supported by plates C.

You should also consider making B. and C. box sections, so placing a plate on both sides of the tube with a strip in between to close the box. Or use rectangular box-sextion like I did (60×20)

Tubes only need to be around 16mm in diameter with a 1mm wall thickness. Box sections need to have 1mm wall thickness and single gussets 3mm.

Below are images of a braced GSX1100S Katana frame.
The bracing is designed by Mr.7/11and welded by Postma Motoren from Haarlem (NL)

Piston-deck height

Deck height is defined as the distance between the top edge of the piston crown (with the piston at TDC) to the edge of the cylinder liner. The closer the edge of the piston crown is to the edge of the cylinder the high the compression ratio will be.

So if you have pistons that are 10.5:1 and they are 0.010″ below the edge of the cylinder and you are able to reduce the deck height by 0.010″ then the actual compression ratio of the cylinder will be increased.

The reduction of the piston deck height can be accomplished in several ways. Machining the cylinder block is the most common method.

A word of caution you must know exactly the minimum valve to piston clearance that is required. this varies in different engine designs. To increase the piston to valve clearance usually the valve relief pockets on the piston’s crown are enlarged or the height of the piston at TDC must be lowered in the cylinder.

If you read my previous post about ‘AIR DENSITY’ in this thread then it will be easy to understand the advantages Nitrogen has over Air, for those who haven’t, I would recommend to do so.

The first advantage of Nitogen is for it’s use in your tires, by doing so you will eliminated tire pressure build up, this is a really important factor in order to maintain a tire’s performance criteria. The Racing Displines of Road Racing or Drag Racing require consistency of a tire performance and the use of Nitrogen will give you that advantage.

In Drag Racing when using an ‘Airshifter’, the use of Nitrogen will add the the unit’s reliability ( No Water contained in Nitrogen) and you will find that the shifter activation responce time is faster.
