Z750,
GPZ750 A1,2 and 3
GT750 shaft,
Zephyr750,
ZR7, ZR7S
even the last of the 650, F2, F3 and F4 will fit if you want.
The fin shapes vary from rounded on the Zephyr to squared off on the GPZ and ZR ones, like yours are now. There may be differences in cam chain tensioner, but all run a hyvo chain.
What is wrong with yours? I have a set of GPZ barrels with the corners filed round that need boring to 1mm oversize or to take 810 Wiseco 3mm oversize.

After fitting a new valve cover gasket i noticed i still have an oil leak. Looked at the engine and just noticed a leak from the cam chain tensioner. On closer inspection it looks like somebody has used chemical metal or epoxy putty around it so i might have a crack. Theres a definate oil leak from there. Wont know how bad it is until i pull it apart on Saturday

If your bores and pistons are OK, you'd be better off getting it welded up professionally.

You might get away with a glazebust to allow your piston rings to form an effective seal, best to repair yours if possible if it runs ok
