Ever since April of this year when the bike ran a little warm in Death Valley I have had problems. Heard what I thought was lifter noise when I got her home, pulled the lifters and yep the rollers were scored and the roller pin on the lifters were very loose. Couldn't see much on the cam but the lobes appeared OK in the bike. Put the new set of HD lifters in the bike took it for a test drive and still had some lifter noise, decided to pull the cam and see what's up. Cam lobe on the outer side very wiped out (Andrews - EV23) opted to put in the EV-27 (FLHT) so it's heavy, installed the same new lifters (under 50 miles) onto the new cam. Fired it up, lifter noise at it was is gone but then I heard additional valve train noise that is supposed to be normal with the ev-27. Ok fine, i'll run it, lately it's been getting worse, Andrews says maybe gear clearence is excessive and causing ticking sound (not a ticking sound),, today got way worse on a 200 mile run, thought it was going to explode! under a light roll on or roll off the noise gets pretty loud (clattering engine sound) goes away (96.2%) under a slight load. Sounds like it did when I had to change the lifters before but worse. Would it make a difference under load no load? am I missing a problem here? don't want to waste another cam and lifters. Did I make a mistake when I put the almost new roller lifters on the new cam? Oil pressure is good! 30-35 on the road with S&S pump and cooler.
