need advice on rebuild

Recommended Posts

I have split my cases on my 03 crf 450 due to a bad bearing on the transmission side. I am looking to get some more power out of the beast so i ordered a 12.5 high comp piston, yoshi exhaust and a vortex ignition. I am also thinking of having my head ported. I have read good things about rhc and was wondering if everyone is happy with the results of the head work. Also whats a ball park cost of this work.

call back, save the money on the ignition, order an 05 CRF ignition and harness and air boot, with the extra dough, order an RHC 187 cam, send the head out for porting and put a 13.5-1 piston in it.

It'll probably be more than what you ever asked for...

I would send the head to RHC and have him port the head and install his s.s. valves and valve springs and also the J&E piston. He is the master when it comes to getting both power and reliability out of those machines!
