Hey yall, i was kinda wondering if a hotter cam would be worth 140 dollars for my 660 raptor. I need more power!!! I really don't want to bore it or install NOS. The bike has an FMF full system and K&N air filter and jet kit. Also would porting be good for my raptor?Why?How much? I mostly ride on gravel roads and mining property. Thanks.

 

Holey $hit it's a raptor 660 why would you need more power!!!!!!!!!!!!!!!!!

 

I am 15 and its all about the competition. I have a little YFZ problem if you catch my drift.

 

LOL, OF CORUSE its worth your investment, throw a cam in there and while your at it go with some higher compression.
