just curious - who is building the hot motors for raptors? i see curtis sparks has a 690 kit but i haven't seen others. just wanted to know who is building them and who is running them? what do you think? im thinking mostly xc and some mx riding...
i don't have the quad yet- just puting together some info for future reference

 

trinity also does the engine mods, 686 and 720 i believe, check out some posts from kingraptor, he has the 686 and it sounds wicked nice.
