HAs anyone tried the 2003-05 Cam in the 2009? The last Yamaha 450 I owned was the 2003. It came off the bottom and pulled good all the through the RPM. I had the motor done on that and full exhaust etc etc. I then went to Honda's from 05-08 and had motors everything on them and those motors were awesome I mean unbelievable. I then had an offer to go back to the Yamaha shop that I used to ride for. I just went and picked up a 2009 and have already had the motor done, exhaust, U4.2, HC piston, ENZO suspension etc etc. I love the smooth power but its lacking the bottom to mid that the honda's had and the bottom through top that the 03 had. Opinions appreciated.
