Hi, quick question, whats the difference between a zx400 engine and a zxr400 engine?
And can you put a zx400 engine into a zxr400 frame?
just wondering as i know someone with a zx400 engine that i am thinking of buying.
Cheers.

if its a ZX-4 engine out of one of these



then it can go straight into a zxr..

its basically an H model engine, although there are rumours that the cams are sp spec without the adjustable sprockets.

also it wont have a slipper clutch, and the inlet stubs are 1mm smaller than zxr ones, so swap them over.
