Supposedly it works fine, but I don't know from experience. If you could, please post your progress as I'm considering doing the same thing. This reply isn't very helpful but at least it'll bump you back up to the top for prime-time.
I've looked for motors on ebay, on other forums classified sections, local dealers, racing web sites like 2wf.com etc... As far as my mechanical ability, I've taken the bike apart a few times as it was crashed hard and needed a fair amount of lovin'. With time and a manual I could do just about anything as far as repair and maintenance on my M750 and my 996. In fact the only thing the "mechanics" have done so far during worried visits to the dealer is swap the belts and check the valves. I'll use the M 750 oil cooler mount if it will directly replace the ss valve cover. Seeing how they are both carburated, I shouldn't have any electrical issues, should I? Someone brought up the point that I might have some ignition issues, I believe the engine tht I'm going to buy comes with the coils. Also someone mentioned that the exhaust collector on the M750 may be smaller in diameter, what would this do to the HP and Torque curves? Thanks for your responses. -Jesse
