Kenneth, you mentioned break-in - so what breakin procedure are you employing? Is it because of the Piston? you are doing a certain procedure!
Not to jack however related / You got me wonderin now if I did mine correctly for the last cam job which was keepin the cam above 2000 rpm for 20 minutes after initial start-up, after that drive as per normal. This is what i have planned for my Crazy Spartan.
Anyhow it sounds real good!
