yeah cam mod is done. i was thinkingof a bigger carb or rev limeter

The carb that comes on the yfz is going to be tough to beat. It is one of the best performing carbs you can get. You shouldn't need a bigger carb unless you do motor work.

I have the Boyesen Quickshot and yes it got rid of the BOG.You can change the front sprocket it wont give you anymore HP but it will feel like you have more power.Isnt the stock YFZ rev box go to 10,900 I say that high enought.

i think gettting a rev box on a YFZ is pointless... i never hit the rev limiter as it is- they already rev to the moon...

on a raptor 660, yes, i think it is a worth it... on a yfz, i dont...

if you'll look a dyno, youre already losing power way before youre gunna hit the rev limiter, so you should be shifting anyways... the only thing it maybe does is allow you to shift into the next gear at a slightly higher RPM...
