i'm not sure what they were called over there. over here we have ZZ-R and GPX 250s. mine came from a '95 i think. they are 30mm. up from the 26mm stockers. being keihin carbs, all the tuning stuff is available. they were a definite performance and economy improvement for me.

i still need some bigger idle jets and had to drill the mains a bit. on a stock TT600 the jetting would probably be very close.

my bike has a 19L Acerbis tank on it. it has a bit more room around the carbs than the stocker. it still required some reshaping with a hot air gun. i reckon you could do the same to the stock tank. just go steady and don't get it too hot.

and suspension wise, i used a complete front end from a WR426. it uses the same lower bearing. the stem is about 30mm longer. and uses a different top bearing. i got an adaptor machined to knock into the frame and take the wr's bearing. i also had to add 8mm per side to the steering stops. this worked well for me as it raised the handle bars. ( i'm 6'2" )

one other bonus with the WR stuff is it came with a speedo drive. the WR cable works with my speedo and is surprisingly accurate. i was surprised when the stock fork springs ended up being pretty good for me. the brakes are heaps better too.
Where you come from is gone. Where you thought you were going, Was never there. Where you are, Ain't no good unless you can get away from it.
