When I called Bullet and asked them to recommend and grind a cam I did tell them I wanted some gentle ramps so as to no beat the valve train to death. Told them I wasn't afraid of a big cam but didn't want to have to be changing valve springs a couple times a year. I've been checking the lash in the spring and the middle of the summer and it's been rock solid with no noticeable changes. I idle the motor at 1100-1200 rpm to make sure the rollers are getting plenty of oil. So far all the pushrod cups and rocker arms are looking fine.Dave
