Any know if a fh770d cam will fit a fh721d block.im trying to get a little more lift and duration.
They are the same part number, so yes it will fit, but it's exactly the same cam. Best thing to do is call Precision Cams and ask if they can re-grind your stock camshaft into whatever you want.
As far as I know, there isn't much of any performance parts for the Kawasaki motors except for the big single (FC420 I think)....if you look deep enough here, there's someone out there making rods and flywheels....I don't know who it is tho.
All I know is that if I had the chance to build a Kawasaki, that would be my motor of choice....the way the heads are built, they seem like it would have so much more potential. I'm not sure why there's a lack of performance parts for them.....they are great motors!!
