Hit a dead end with my bike and I'm looking to see if anyone experienced anything similar to this before and if so, how they solved it. A little background info:
I bought this 1990 Sporty 883 back before winter, stock with 30xxx miles and have been slowly getting it to where I want it since. This is my first Harley so most of the mechanical work is first time stuff for me. It all started when I pulled the cam cover to cut it down (one of my less bright moments), accidentally pulled out a cam, and was forced to pull them all and re-time everything, which I'm sure I did correctly in reference with the manual. In reinstalling the lower rocker box cover I think I tightened everything too quickly and collapsed a lifter because when I fired it up for the first time after putting it back together with new oil, I heard a pronounced knocking up in the top of the engine. I assumed they were probably original lifters anyways, so I bought a set of four new Feuling lifters and installed them.
After several heat cycles, letting the bike warm up and idle, and even taking it around the block, the noise is still there and when I pulled the covers off to check the rocker arm, I can push it down at TDC meaning my new lifters aren't pumping up. The pushrods are factory one-piece non adjustable, and they are in there proper positioning with exhaust/intake. Before installing the new lifters I had them in a cup of fresh oil and plunged them each a bunch of times with a pushrod to start to get some oil in them, but I did not leave them overnight. Even still, at this point if everything in the oiling system was functioning properly the lifters should have pumped themselves up.
That's about where I'm at right now, not sure what the next move is or if I should be checking anything else next. Could it be oil pump related? Any help is appreciated!
Here's a before and after just because.
