How many parts a interchangable and which parts can you swap that would make your quad faster and better for CC racing

the cam mod will get you up to yz timing .the ncvq needle will give you more adjustment for fuel flow. not sure for xc but most of the mods from the yz are more geared for mx.i also use the yz rear master cylinder to get rid of the ressy.i'm sure some xc guys will chime in to help you out though.

you can take the wiring harness,cdi,crank,stator,and flywheel pretty much the electric system and put it in the yfz450. You'll get about 7-10 more horse but it change the power curve a lot. She'll get pretty mean thats what i did. i don't know about xc racing it might be a little to hard hitting. i race mx.
