I have new 06 Street Bob that I plan on installing a SE 95" kit and 204 cams. I have 250 miles on the bike and would like to avoid changing the cam bearings, especially the inner one's. Any advice or opinions would be greatly appreciated. Also, the back page of the instructions calls for checking the piston to valve clearance and valve to valve clearance, I will be using the HD SE head gaskets, is this neccesary with this set up??
