My bike has about 400 miles on the following jetting: DVP needle #5 position, 165 mj, 38 pj. I switched to this jetting after going to yz timing. The bike has always run great and started on the first kick. On Sat. The bike ran fine but each time I shut it down it was harder and harder to start. Once started it ran fine. Until I messed w/the pilot screw. Then it ran very lean and idled high. If I tried to turn the idle down it would just stall. In the end I could only get it to start w/the hot start on and turn the idle up. I changed the plug w/the same results. I diassembled the carb and cleaned it. The air filter was fine, not over oiled. I have only had the bike out on a few short street runs in the past two months. There was alot of mud and crap in the tps connector straped to the frame. The carb was spotless except a little crud in the tps cover but in my opinion not enough to make it run bad. I have not had a chance to test the bike yet. When I do it will be on a fresh tank of gas. Does anyone know, if the tps connector had a bad connection would I experience these symtoms. I have had the bike out in temps from the 40s to the 90s w/out any problems. Sat. was about 65 degrees. I don't see how it could be a jetting problem.
