I reported this a while back but after starting up the bike this spring i’m a little worried. Does this sound normal to you guys? That “knocking” noise sounds like its coming from the rocker box of the rear cylinder. Or am i just paranoid? Thanks for any input:
Sounds like mine. Quited it down a bit but running 50wt. Have 25k on mine and it has sounded clacky since day one. If you have adjustable push rods you just might want to check and make sure their in spec, if so just ride the **** out of it.

beauty, thanks ochog1, i will do just that, ride the **** out of it!
Mine was louder until I put S&S premium lifters in it . Now its really quite. One of my stock lifters was not pumping up like it should. The S&S coast more but it was worth it to me. Or Red Line makes 20W60 oil too.
If both cylinders were the same I wouldn't be worried about it but that rear cylinder definitely has a distinctive taping sound compared to the front, what RPM are you idling at?

cool maybe i’ll look into those lifters, thanks for the feedback

should be about 1000 rpm but i dont have a gauge to measure it. Hmm. Could old gas cause that sound at idle? Its the same gas that was in it when i stored the bike in November with stabil. Hmm i wonder if i should look at the lifters like apache snow suggested or the push rods
For anyone paying attention to this, got this info from Aaron at Hammer:
“It sounds like a valvetrain noise. I would say check to see if your rocker shafts are rotating back and forth. You can tell by pulling each of the big bolts on the pushrod side, one at a time, and looking for witness marks where the shaft runs into it.”
And while you're in there you night as well install some lockers.
got em in there already, ha! Hoping this noise is something simple. Is it possible that the rocker box bolts are not at the correct torque spec causing that noise?
