so my stock 07' 300ex ran great this weekend, but keeping up with my uncle(500sportsman) and step dad(440ex) wasnt easy, i can get my uncle off the line but then he catchs up, so i was looking to get a new cam and exaust(after mine fell off :p)

i was looking at the fmf powercore 4 full system https://www.fmfracing.com/Mode/Category/129

and for the cam useing a hot cam Hot Cams Products, Inc.

how much power will this give me?



*wouldnt let me post in performance section

With the full exhaust system you will see about an 8% hp increase. Probably in the area of 3-4 hp. The hot cam will add around 1 or 2 hp.

Agree^^^^!!Tires help a lot.As for chain and sprockets.I'd stay stock if your woods riding.The stock setup is fine for that.If anything get a better chain that has a master link.

timeing curve?
The rate the timing advances with engine RPM. This is built into the CDI.

I think most aftermarket CDI's can give you as much as 1,000 additional RPMs.

Get a nice aftermarket foam filter(uni, superflow. notoil are all good). Remove your airbox lid and jet accordingly.
