[QUOTE="lemmy, post: 1315379, member: 93740"] Ok, I started the bike and let it idle for about 5 minutes. Then I rode it back in forth in my neighborhood 6 times (about 0.1 mi each way) then let it idle another 5-10 minutes. I thought the problem was fixed (after the carb dip). But then out of the blue it started wanting to die. Then I screwed in the idle screw a bit (I didn't have it anywhere near all the way in) and it idled ok after that. I finally shut it off and immediately checked the compression. It was about 150+. I thought that was high, so I released the pressure and did it again and got the same results. The odd thing is that if I screw in the air screw (from 2 to bout 1.5) and it starts to run rough, and I screw it back out to 2. It takes several minutes of revving it to get it to where it will idle again at 2 turns. So the carb is surely clean. Compression isn't a probelm. Jetting is at least ballpark. And the reeds look good (but it is the crappy RAD valve). I can't think of anything else. The bike is running fairly good though. [/QUOTE]
