That is ALOT of money.

You might be better off with the GYTR Head that comes ported with the aggressive cams for about 2000$.
You'll then have a complete spare head, and a brand new one that's already ported for your bike with all the goodies installed.

I had my bike done by C4MX. Frenchie (the owner of C4) used to be the factory Yamaha engine builder. He did the motors for Motoconcepts Yamaha this past season, and he sells the exact same packages to the public. I would really suggest giving him a call. I absolutely love the motor and suspension he did for me. So much actually I bought a 2010 CR250F and had him build it too.

I would like to give him a call and price his stuff. You wouldnt happen to have a number where I could reach him. I cant use all the power the bike has but I have allways wanted to build a bike up. Now I can do it. and want to. If you could leave me his number I would appreciate it.
