Nearly there.

Will everone stop cutting up 750 slabby frames.

I've looked at this, and you'll need to do some welding of the frame to take the rocker pivot. Jos Hammer runs an L/M set up on his Slabbie, so I guess he'd be the man to ask.

In all seriousness the 1.41's you're doing is bloody quick. If I can get Below 45's I'll be happy and running top 6 in the class. Though I've got a bet on with a mate as to which of us will get in the 42's first.....

Did 1.45s on my old bog stock D****ti 749 road bike. I guess I've got to beat 1.41s on this. In other news It's ALIVE! Fired up after having to source some 38mm carb rubbers in a panic. Just ridden it round the yard for the first time.

Racetech in the States have a really good on line calculator for specing fork springs. http://www.racetech.com/ProductSearch/2/Suzuki/GSX-R750/1988-90 Ok it's for stock bikes but it gives you an Idea. The site is really good for cross referencing spring lengths and diameters too. I wanted a set of springs for my 750k forks but every specialist I spoke to in the UK said they couldn't supply them. Not wanting to wait or pay shipping from the states, I did some homework then phoned up Ktech and ordered set of springs for a 1999 zx7r. Arrived next day and fitted perfectly.

T minus 7 days to Cadwell Park. Spent the day making a wiring loom. 80% done, but enough to power up the Ignitech, and check it all works. Carb rebuild, and sus out the crank sensor configuration, and I should get a tune out of it tomorrow.

1100L frame is taller than a 750m frame by about 12mm. I run a 7/11m with 180/60 rear tyre, 10mm shorter rear dog bones, and stiffer springs. Other wise the suspension is stock but refreshed and carefully set-up. It handles ok. I'm starting another build around a 750k frame, as I've heard they're lighter better handling. I won't know for sure until I finish the bike which is better. I know I will definitely be fitting lighter wheels, and better brakes, as well as the other mods. The current bike takes a lot of effort to stop and change direction.

you may have to fit a different length push rod, but yes it's a straight swap otherwise.

Sorry about the lack of updates. Let things slip for a while on this. Been cracking on with all the little jobs. Binned the hydraulic clutch, and fitted a bandit 600 cable set-up, made battery box and mounted that along with the other electrical hardware. I've modded the road style fairing lowers with the catch tray from a set of crashed GSXR1000 K8 race fairings, which has worked out really well, that's being painted now. The biggest hold-up has been the wiring and igniton. There was a cock-up with Ignitiech with Payment, but that was sorted last week, and the kit arrived this morning. First impressions are good. Loads of extra functionality, easy to use software, and he quality looks good. Entry is in for thunderbike xtreme at Cadwell at the end of the month, Shake down in 2weeks at a local airfield.

Doug at G19 will sort you out.

Presumably you have to run a silencer for Cadwell? Collecting parts for a Turbo Slabbie track slag currently, so interested to know what sort of silencing a turbo bike needs

Yeah, I hear good reports on the Ignitech stuff, they've been superb to deal with so far. I've an entry for Oulton in a couple of weeks but I'm not going to be ready. Unfortunately my day job means I probably won't be out until the final round. Looking at the Results from the last couple of years, I'm running top ten times on my 7/11m road bike at trackdays, though I need to find @5 secs to be at the pointy end with yourself. I think that's doable with some seat and set-up time, bearing in mind this bike will be 20ish kg lighter and have better brakes. If I wanted to run in sport, I'd have built it with a 750 motor.

Way Behind schedule now, but it's taking shape. The very helpful Ignitech are supplying me with a programmable ignition, quickshifter, shift light, basic loom, and coms lead, all for 240euros delivered. That on the face of it is a bargain. we'll see what turns up....

Bit of wriggiling to get the motor in the frame, you need to remove the sump and cam cover breather, and refit them once the motor is in position. Plus you need to drill the lower rear engine mount out to a larger size. Simple.

Taken from another forum. These were shot at the Manx around 5 years ago

Ha,Yes, That's me. The motor and front end in this bike is from the chassis your lad bought. The B12 lump will get a turbo and go into another project.

There was nearly some violence today... This things been fighting me today. Rear brake caliper is unserviceable, thread for the bleed nipple on one of the front calipers has stripped, and one of the swivel fittings on the oil lines has shat a seal. I choose to ignore all these issues and make a headlamp blanking plate. There's a deceptive amount of shape in the front fairing, most of the versions you can buy look wrong imho. Then I got the rest of the bodywork fitted up and away for paint. If anyone has a serviceable slingshot rear brake caliper spare could you let me know asap. Cheers Duncan.

been working awqy for the last couple of weeks, but I've got a bit of time now to really crack on with this build. Today I got some slicks mounted on the rims, fitted the discs, and wheel bearings and my talon 520 sprockets. Modified the swingarm to fit paddock stand bobbins and a shark fin. Started repairing and modifying the body work, then fitted the Swingarm and wheels so I could get it rolling. This bike is starting to scare me. Now it's rolling I can take it to my workshop tomorrow and start to really crack on with the build and start the fabrication and machining jobs

More progress today. Frame yokes have been lightly blasted, I went over them with a decorators foam abrasive pad and lots of WD40, they now have a lovely raw brushed finish. Then had to rebuild the bloody great Mikuni for my nate who does my blasting and powder coating to go on his draw through turbo1100 slabbie. Ny wheels should move up his priority list now. Started the build this afternoon, lots of it is dry build at the moment so I know what I'm missing, as this is mostly being built from random shit I find in my garage. The bits I aquired yesterday included a prettier flat top tank which I'm going to run alrhough it needs some work. I want this finished in six weeks. Gulp

Managed to spend a few hours on this today. Frame collected from the blasters, yokes stripped and superfluous bits ground off, Forks rebuilt with new seals fresh oil and 0.95kg springs, calipers stripped, cleaned and rebuilt. Spacers machined fro the front wheel. Lots of money spent on bearings, posh fasteners, brake pads, chain, tyres and other shit. Hope to start assembling the thing this weekend. I've decided on the Sietto paint scheme, as it is simple to maintain. Black paint and a load of red vinyl. Went to pick up a few odds and ends this evening, that I need to get this bike built, you know engine mounting bolts, swing arm spindle. Left with another frame, tank, swing arm, and the makings of another bike.It seems I'll never learn

I've decided to not brace the frame to begin with, though the frame is currently having the anodizing stripped and will be left bare alloy with just a once ove with a scotchbrite pad and some WD40 to protect it, so if I decide to brace or need to repair it in future it shouldn't be a drama. Only other thing I've done is mount the rear sets on some adaptors.

been collecting parts for this build since last summer/ Finally found a day spare to start the build a couple of weeks ago. So first job was to sort the £11 frame. See how skilfully it has been modified..... Now I could of just whittled up a simple bolt on rear subframe, but I want the bike to look fairly period correct, so managed to source a sub frame off another street fighter bike. Of course the replacement subby and the original had been cut in different places, leaving a gap, so I had to be a bit creative when joining it all together. Turned out ok, and the frame is all square.

I'm building this bike to compete in the Bemsee Thunderbike extreme class. The next few posts are copied from another forum, so I apologies as the time line is a bit out. I started the build in early April, the last picture is as it stands this evening. Ok time to stop fannying about, entry is in for Oulton Park on the 17th-18th June in the Thunderbike Extreme class. Looks like I'm going to finally break my Racing and Oulton Park duck. Just one problem. I need a bike. Ingredients 1x badly streetfightered Gsxr 750g frame and swing arm £11 from Eblag. 1x set of Gsxr 750k forks and brakes 1 x Gsxr 1100l motor, 1x set of Gsxr750k or 750m carbs 1 x pair of Gsxr750rrk wheels 1 x Gsxr 1100g shock linkage 1x Micron 4-2-1 exhaust. 1 x Brembo master cylinder 1 x Yamaha R1 4c8 nos rear shock 1x pair of zx9r Harris rear sets 1x Dyna 2000 ignition. Various other bolts brackets and widgets.plus some Eblag sourced fibreglass fairings, and a Yoshi style seat unit.

It's all here to play with Mark. http://www.gearingcommander.com/ Note that the 750 and 1100 primaries are very different.... an 1100 with 750 sprockets is less than spritely, but does have theoretical 190mph top end. Ask me how I know.
