I have a 11:1 compression pistion in my raptor. The bike is stock, execpt for a jet kit. WHat i need to know is... When adding compression, will this require me to re-jet? it does idle a little loopy now, but it seems to run ok, however am I losing power by not upping the jet size...I am getting a pipe soon, and will re-jet then, however, i need to know can i use dybo-jet's reccomended jetting for a stock bike with a slip-on and will the jetting be ok then? thanks

 

11:1 stock bore no reason to up your jets

 

Doesn't a higher compression piston, require a new cam to accomadate? To get the best out of the higher comp piston? Isn't having this higher comp piston pretty much a waste without a cam, springs, valves to go with it?
