i have an 09 yfz 450r with a gytr full exhaust gytr air flter and a power commander and have recently bought a high compression piston 13.2:1 i do not want to go any higher because i dont want to have to run higher than one hundred octane. any suggestions without boring over to make some more horsepower gains?

 

you can get a cam for it or just do he cam mod

 

yes i have thought about the putting in a bigger cam but the one in the yfz is already pretty high the dealership said if i went stage 2 it wouldn't be worth the money and the stage 3 would be to much top end

 

i would look into doing the cam mod, you just rotate your exhaust cam 1 tooth clockwise, doing this will increase mid and top end power, its a free mod you dont have to buy anything to do, just take your time and do it right, alot of people say it makes your bike run cooler also, heres a write up of how to do it instead of me trying to tell you.
