Frost, glad to see you have gotten into this one. I'm fresh out of ideas and all that I can think about is riding Jawbone cyn. tomorrow. Good luck manther. I'll check back on sunday to see how you did. Thanks, and thanks for the help. I checked the valve clearances and the intake was perfect, right in the middle of the range specified in the manual. The exhaust was off though. They were at .33 and .30. I moved them from 178, and 179 to 180 and 181. Which put them right around .30. I plugged up the hotstart tubes, to take them out of the mix. Started it up and it definatly ran a little smoother, but still died while idling. But I had the idle way up and the pilot screw bottomed out. So it was probably pretty lean. I started trying to richen up the pilot screw some but it kept dying on me before I'd get a chance to back it out any. So I backed it out a little with the bike off then started it. But it died again. I took off the air filter, It ran a little quicker. (The revs were higher) It kept dying on me with a pop at the end. Sounds lean doesn't it? Also about that slosh or gurgle sound I described earlier... The one that occurs right after the bike dies... I've decided it is not coming from the tank or the carb. It is coming from the radiator I think.
