Coming along with rene so see you all there ! not able to ride a bike then but lookin forward to this weekend.

Gonna race one next year currently gathering parts and start building the coming summer did some research spoke several people wich race a slabby. They say brace it and race it

Don't want to piss on your parade but as far as i know the bigger the pipes the lower the gasspeed wich can result in even slower spool up. Probably smaller turbine wheel and housing wil have bigger effect in faster spool up. increasing pipe sizes can result in higher bhp output but i think that wil only work if you do really big numbers . correct me if am wrong

On holiday on that date damn

Marco was the one who got me in to this turboshit and helped me out big time when i made the first steps towards BOOST Just wanted to share this pic, The teacher on his pupils bike wahah

The good old days

Hi mate welcome back

There are some around with approx 300 bhp, mine had 250 and an even amount of torgue. Must say after three years the alloy halfmoon thingies wich keep the crank in place where totally worn loads of sideplay in the crank.

Yeah Nico ain't cheap I asked a price for some framerails for my bakker it was expensive I decided to take some scallops out instead of getting some new ones made

Found a chap that can bore my slabby flatslides to 33 mm i think this wil do on the standard engine i will use according to the previous given advice. Plans for the future is to go 884 then i wil probably need bigger carbs.

Great info thanks well not such of a racer yet and hopefullymostly racing in the Netherlands on probably Assen Zolder in Belgium and Offcourse Spa it seems like i can get away with the slabby carbs

Been building FI bikes for 8 years now and have no experience what so ever with NA engines so i am a bit in the dark. Here's the case: I am building a yoshi rep for racing using a dothead 750 engine and a mix up from a vampire downpipes with open yoshi can and planning to use pipercross filters The engine stays completely stock I really want to use the stock slabby flatslides wich are in good nick I am worried that using the rather small slabby flatties wil choke the engine and bring down the horsies. Can anyone tell me if this wil be the case and i need to buy bigger carbs ? Or can i get away with this set up using the slabby flatslides It would be much appreciated if you can share your thoughts or experiences with me Thanks in advance

230 on about 10 psi i needed a 260 mainyet to get it rich enough under boost without thunderjet so it was riding like a highly tuned two stroke on of on of then fbm adviced me the thunderjet. i experimented with different gasneedles also for a smoother ride wich helped out also it does make a huge difference

Yes a thunder jet on the mikuni when you use it you can use the main jet to tune between 3000 and approx 5000 rpm and the thunderjet to top off fuel at higher range this wil improve drivability on low speeds it gets smoother in that range you just cannot get it smooth with just the idle and mainjet cause you need a mainjet as big as the emulsiontube when you have over 200 bhp then ridability in midrange is shit thunderjet worked for me

Your asking questions obviously cause you want to improve things referring to how it was wich worked is perfectly right imho cause this can help you. you ask questions we answer. if you want to convert to efi check wizzy pop slingshot on here

I know but the bike didnt do 270 when it was owned by gjg as far as i know so if you have all the bits just put it back but install a thunderjet to get midrange good changing the place of the carb wont change anything in how the bike runs on low rpm it al comes down to tuning there nothing wrong in how it was designed and installed by gjg as they say Never change a winning team

Still thankfull that GJG shared his drawings with me so I could copy his system its great to see that his bike is still in 1 piece I love it it's an iconic bike! Wich brings back good memory's

No he did not indeed on his old set up I have seen 230 on the dyno at street or track don't know what GJG did after that. Pascal installed the s&s and al the trick stuff after he bought it from gjg to get bigger numbers

This is your bike with a hsr 42

I spoke too sean multiple times in the past and he gave me good advice while buildin the kwaksuki rising rate just won't work he has been there and binned that plan the carb wil flood. he told me that on woody's cat the last 100 mtr on the strip was done with a shot of nos cause the problem with drawthrough on big ass hp is getting fuel in the floatbowl he mentioned that a bigger floatbowl does not solved this problem only thing you can do is order the seat and needle that allows you to get more fuel in the bowl faster gert jan had a hsr on the turbonetics in the past mounted with a rubber you can easily order at mikuni

Well i hope for you it gets sorted good luck

I wouldnt send my bike back to a shop that wrecks it. I would try to negotiate about the refund and get it done elsewhere

Whatta mistaka to maka!!

I always use a catchtank wich the both breathers are attached to, if you use a big enough hose from the clutch cover too the tank this wil also be your returnline

I always enlarge the breather on the cover and Make and extra in the clutchcover. so you might want to try that first before spending money you can check easily by removing the oilfiller plug and push in a big long hose there to prevent it from spitting oil while idling
