Need opinions
I just got done installing new inner/ outer cam bearings, tensioners, and lifters into my bike. I tore the rocker boxes down so i could use the stock push rods. I cranked the motor with the plugs out until the oil pressure light went out. Put plugs in and fired it up. Runs great and the pressure light stays out but the valve noise is very noticeable. I let it run for about a minute then shut it off and looked for leaks. Restarted and let run for about another minute and the valve noise persists. Does it take a while for the oil to get to the roxer boxes? I left the new lifters in oil over night then installed them but the bike sat another day before i started it. Im hopin the lifters need primed and havent got oil up the pushrods yet. Should i just let it run? Runs great, revs great,no noises besides a tapping/ knocking from the lifter /pushrod /rocker area.

Thanks! I spent a lot of time last night searching the internet and it sounds like the lifters are the problem and that its not to uncommon of an issue. Im gonna let it idle for a while and see if they pump up. Hope i dont have to tear apart again!

my bike took a little while for the noise to go away after doing the same job you did, he dont need to watch a video for adjustable pushrods, he said in his post he use the stock one.

Dont worry. Let it warm up idling, don't rev it. A warm engine is a different beast than one that is cold, especially after any type of rebuild where oil needs to be but has not had time to get their yet. (if that makes sense)

Thanks everyone. Good news! I let it idle for about 10 mins and everything is good. I could actually tell a difference right at startup on the noise level. Then as is it got warm it sounded much better. back to the normal "sewing machine" levels. Started it back up a couple times as I cleaned up the garage and it seems perfect. Actually starts a lil better than before unless its just my imagination.
Great feeling to know that its back together and everything is ok. Great satisfaction from working on your own scoot!
Now back to hibernation mode on the lift and Battery Tender. Waiting on my HD Premium Indoor cover to come in that the wife got me for Christmas.

For future reference, lifters cannot just suck oil inside themselves by just submerging them in oil.
You have to use some plastic tubing or heater hose and a shop vac to suck (pre-charge) the oil into the lifter.
Not sure if it's necessary to pre-charge them but I did it that way for piece of mind.

I was going to just reuse the stock lifters as the bike only has 21,500 miles on it. But the indy showed me a mark on the intake lobe of the front cylinder that indicated the lifter roller had dragged on it a few times. So I just changed all four.
