I have a 2007 LTR and can not keep up with my friends who have a upgraded yfz and raptors. I have a yoshi exhaust, cherry bomb, K and N filter. and that's about it. Where should i go from here? Was looking into getting a big bore kit, but do not know which one i should get, also a PC5. But is that a waste with the cherry bomb?

Thanks man. I appreciate the advice. One more question though. I see a lot of these big bore kits have different piston sizes. What would be the best to go with?

I try to go smaller since the bigger you go the more your cutting into wall clearances

Around 1000-1300. And just want a machine with more power and top end speed
Top egg speed for long periods of time will seize your connecting Rod. These machines ain’t made for that. You running stock tires and stock gearing? How much do you weigh
