This is great ,I recall people saying that it wouldn't work and would burn out the ecu but if ,like you you get the right cops it works

That's not it but right website

Found a thread "gsxr head on a gs1100" on a forum called psychobike unfortunately I haven't figured out how to link stuff on this tablet,username ,racing jake, have some info if you can find it, it may help some

It would be great if you could, maybe it could become a pinned thread make it easy for anyone interested to do the same

@fatblokeonbandit had one for sale on page 2 in the small ads.... Hth

I've now come to realise that it's Clive Gonna Turbo Owt ...

Colour tune is a simple device, a see through spark plug! As you adjust the pilot screw the colour of the burn changes from lean to rich never used one on a bike but did on cars

I remember way back reading an article about formula ford racing that the top engine Builders would check crate loads of cams for the "one" where the tolerances in machining have a little more lift ,same with conrods find the lightest set,rocker arms that had the highest ratio, Etc the rest was used in engines for kit cars and series that allowed modification, mind you back then factory machining and assembly was nowhere near the standards of now or even the 2000s and a blueprinted engine had a definite improvement over a Friday afternoon or Monday morning one. I also read about acid porting,where they fill the ports with acid for an amount of time it dissolves the metal at a set rate ,and leaves a stock looking but larger port still with casting lines etc,just a bit bigger there's some sneaky buggers out there

No not all Captain thank heavens for translation tools

But a thorough decoke and a little lap dance for the valves will maximise what you've got ,what about slotted cam sprockets for timing the cams...

Oh bloody hell,time for the left handed drill bits?

Welcome to OSS. Well your lucky to have had the bike from new, know it's ins and outs,there is plenty of knowledge on here should you need help

Your gs(x)750esd is air cooled the oil cooled gsxf 600/750 is also very wrongly know as a Katana in the Americas any looks like this

I have seen where a penny washer was placed over the remains of the stud and welded to the stud as it allowed better access to weld,and then a nut welded to the washer might this help you ?

Oooh we await the details .....

I thought about this when you asked @davecara for that shortstroke 750 , in his thread about converting a 600 I jokingly said about putting a std 11/1200 head on the 750 to drop the compression for a turbo .....

Glad your still about and still have your turbo bike,I found it first on katriders forum but that site is very quiet these days,thanks for the you tube links ,please keep us informed and up to date on your project,we all need a little out of the box inspiration now and then,and your bike and it's engine is something far from the normal gsxf

Well I don't see why not as when you helicoil them you drill it out tap it and wind the helicoil in .... Just don't drill all the way though into the cam chest, found it done after chasing an oil leak on a 600...

@fatblokeonbandit in his I'm a little teapot build described how he got a 180 in the earlier frame Bumped the project thread for you

If the combustion chamber volume is close then I think it'll be a case of bolting it together,with a used head gasket,time the cams and turn it over with plastercine on the pistons squish maybe an issue depending on the size of piston dome Vs how small the chamber is in comparison it maybe the pistons dome hits the head if it's bigger than the chamber rather than valve interference whichever way you'll be leading from the front!!

Have you got any old (or new) head gaskets 1 for a 600/750 longstroke and 1 for a 11/1200/750 short stroke , if so lay one on top or the other to find out if the studs and oil ways align,if so what sizes do the combust chamber measure are they similar.if not try using a 1200 bandit head on the s/stroke bottom end to lower the compression ready for a turbo.... kidding

Thanks @yantosh just scanned through you pics, you've built a great bike man,those yokes and fork brace are really cool pieces, and the fit and finish looks great Damn missed the engine case on first look through...

Damn that looks nice with the katana fairing,what's the seat ? Ducati monster ? Nice choice of baby blue too

Happy days mate, I'm sure that you'll want the extra because it's bound to feel a bit slow after your turbo bikes.....till it gets one of its own......
