I currently have a TC cam (XC grind). I raced on it all year and did several modifications when I built the motor...so doing all the mods together I am not sure what the cam did. I have good all around power with probably more mid range.
I am building a motor for a friend and would like some input on deciding which one to get. We can't afford to hardface the rockers, so that leaves us with the softer honda cams and TC's (XC and MX) are reground honda cams, I believe. Also the XR is much cheaper ($140) (TC $175 plus a core cam).
What increases can we expect for the XR 400 cam?
Is it an all around increase by lift and duration or does it simply move the power band to a certain RPM range by changing duration?
Does anyone have the lift and duration specs on these cams?
Thanks for clearing up the mud.
