No those 1000 cylinders definitely won't fit.





The 2009 to 2010 motors just changed the head right? Maybe the gaskets? I assume you checked part numbers between 2009 and 2012...

and from multiple people, inc Kelsey at RK tek, 11-17 ho cyls, have better porting and port timing from the factory, to net good gains from just the cylinders. add the 11-17 head, or aftermarket head and premium fuel, and gain more. Ski

The 2010 lightweight crank sure improves response though, not sure if any faster than heavier 07-09 though.
