Started my bike up today and after a couple minutes of riding I started to get a clanking sound from my front rocker box and definetly lost power along with some backfiring. Turned around and went home, I removed my pushrod covers and my intake push rod has no vertical movement but it turns easily. My exhaust pushrod is very tight and can't be turned. I am running woods cams, stock"B" lifters, baisley pushrods, baisley heads and roller rockers and woods rocker supports. Any suggestions as to whats going on?
