I've got a 98 ZX9R C1 fitted in my Indy and am thinking of fitting a 2005 ZX10R anyone know if it will fit in same engine mounts and if prop will be the same position? - Anyother snags known?

Your new engine will be fuel injection and your old one probably won't be. This being the case, you'll need another fuel pipe fitting tank to engine for the fuel return.

The engine mountings on the zx10r are not the same as the zx9,I can't see any reason why you can't reuse your old prop in the conversion,also the zx10r fuel pump has a pressure regulator valve built into it,this means you don't need to run a fuel return pipe back to the tank if you use the zx10r pump.
