got my bike dialed in, runs great now. only thing i want to get a stage one hotcam, and a wiseco 11:1 piston. Do i need to re-jet for these? I have a full ypshi system, with a dynojet kit'd airbox, jets. Im running 146/148 dynojets.

You will need to go up a couple jet sizes. When I swapped from the 11:1 to the 14:1 I had to jet up. So you will need to go up a couple sizes. 155/152 will probaly get you in the right when you add the piston and cam.

yamaha660r you went up on your jetting because of your race fuel not your compression.
raptor670 you probably have to go up a little because of the stage 1 cam maybe 1 main up 148/150 MAYBE 150/155 if you had a more flowing pipe system.
