I am on my way to Rath's shop tomorrow he just called my Cam is in. I talked to a couple guys who already got thiers that it rocks. More low and mid range performance with slight increase in the top end. My buddy said the change in power was noticed the second it was in. It even gets better Rath developed the cams with Tom Carlson (TC Racing) one of the top engine builders in the country so talk about quality and performance. Rath told me he was running one when he took 2nd at the last TT national.
