lol my cb right now is not worth a MRT yet, spring time i plan on putting one together once the head gets rebuilt. Which btw i'm looking for F22a4 cam if u know anyone that has an extra one. I'm putting all new stainless steel valves, stiffer springs, A4 cam that's gonna be milled to be a mild performance cam and i believe thats it for the motor. Nothing too big, jus a lil better performance for getting to work and wat not. Let me know bro.
