So i have read a bunch of threads and figured out most of what I want to do to my DRZ. My ultimate goal is to make as much or a little bit more than a CRF450, buying parts and going up in power as the money becomes available. Here is my plan:
Vortex airbox with K&N filter (already have)
FCR MX tuned for stock pipe
Above with Yosimura Stainless exhaust
Athena 94mm big bore kit
Maybe some mild headwork and valve springs
Does this sound like a good plan of attack?
Is Athena the best bore kit for the $?
What compression ratio should the big bore kit be. It must run on pump gas.
Will that compression ratio require 93 octane?
What hotcams should I get? From wehat I hear there are stage 1, stage 2, and newer cams that have no stage designation
Is headwork, valves, springs really required? I am looking for 45-50HP.
Anything else that I am forgetting?
