You will not have to run race fuel, you will just have to jet your bike accordingly.

My first setup was a yfz 450 eater, and you are close.


This setup will give you a monster bike.

11:1 piston, stock bore (High rev can be good)
stage 1 or 2 hotcams

The key ingredient to this setup is:::>>>>>>>
TRX 450R Carb, get it from service honda for $170.

You will have the beast, believe me. If you don't get the carb you will be dissapointed.

Port your head, and make sure you have good air flow intake and exhaust.
