It is advertised to fit 01-06 800/900 motors in the zr3/mountain cat/1m/king cat chassis. I bought it for a project and didn't use it. Put fresh high temp paint on it earlier in the fall. I will get some pics tommarrow, but it is in good condition.
03F5--ya know I don't think it matters. You'll have to do some research, but I have heard and seen several guys running singles on EFI sleds with no changes to fueling, since the stock EFI mapping was "very safe" from Cat. Might help your shopping a little to look deeper into that.
