Enough is enough! I give. It won't start and I'm tired of fighting with it! Ive torn down the carb over and over, read the manual, kicked it countless times and asked tons of stupid questions on here. Still nothing. So... Time to take it to a shop. I've replaced the pilot jet, the plug, checked for spark, put new gas in it, adjusted the pilot screw (This may be the problem and I know i'm not supposed to change it, but I messed it up taking it off). Checked the air vent on the gas tank, checked the petcock, made sure the float was right, made sure the hole on the slide was on the bottom. I have no idea what to do next. My question is what I should expect to spend on repairs. The bike has always run very strong and has never given me any problems. Ive had it for about 4 years and I've put maybe 200 miles on it. I bought it from the dealership used. Things I've gathered from reading on here are that: 1. It could be valves. I just don't think i know what im looking for with clearance and the bike has never given me any symptoms or problems untill now. 2. Could be electrical and not getting enough spark. I don't know how I would test this. I have some tools but no experience with this. 3. It is probably in my carb. i don't know how to trouble shoot this...Aparently I'm in Fresno, California if you know of a good bike shop in the central valley. Clawson Motorsports Honda Yamaha is the biggest dealership in town.
