So...that ticking was driving me crazy so I tore into the top end of the engine again to re-re-re-re-re-recheck the valve clearance. Apparently, the feeler gauges I bought were the problem. The .13mm leaf was thicker than the .15mm leaf, for whatever reason. At first, I thought two leaves were stuck together, but I guess the .13mm got mismarked.
Anyway, I disasembled the set like Old Syko suggested and just used the .18mm, 15mm, and 10mm to check the intakes. The exhaust shims were good, but I had to correct each one of the intakes.
What I did was basically make sure the 18mm wouldn't go through and the 15 would, since I couldn't use the 13mm. One or two wouldn't let the 15mm pass through, but the 10mm did on the intake, so I counted those as good.
After I finish unf*cking my mistake, I took the bike out and got it nice and hot, then let it idle. Sounds like you were right all along, Pacomutt...I couldn't hear the ticking that loud anymore. Now, it was a faint, soft tick that was barely audible of the sound of the engine at an idle. Sounds a lot closer to what I would have expected. Maybe people next to me will stop staring now. hahaha!
Anyways, thanks to both of you for the advice. I think I have it done right this time.
