Alright. I took it out for a ride this afternoon, and I was happy with it. I kept it pretty tame for the first 15 miles, then took it on the high way and opened it up. It's the first time I rode in over a year, so it was pretty exciting too.
When I first started it up, the idle was crap, so I let it warm up for about 5 minutes. The exhaust was still making a popping sound, but pretty low decibles. I turned the idle mixture screws about 1/4 turn out, and it seemed to fix it a little bit, but not perfect. When I got it on the road, above 2500rpm the engine was smooth. I rode it in 4th gear and got the revs to about 5500rpm, and there was a small flat spot, but not too bad. I don't normally run there any ways, so that doesn't concern me.
After I rode it around for about an hour, I pulled into a gas station and the idle was up around 2000, so I turned the set screw down until I was in the 1200-1400 range. I then rode it home and the idle was about 1000rpm. I don't know what that's about. I made sure the chokes weren't sticking, or open at all, and the throttle plates were returning to the set screw. After the bike cools down, I'm going to check and set the over head, because I haven't done that since the rebuild. I'll also warm it up again and go through the dead cylinder test again. I'll try to post another video again so guys can hear it.
