Cdingman Posted March 21, 2010 Posted March 21, 2010 Bike will start just fine, but if i rev it in neutral or try to go in gear it stumbles and has no power. the plugs were a little black so i swaped them out just to check and it had no effect. Yesturday was first day of spring and cant ride. Please Help!
Ttaskmaster Posted March 22, 2010 Posted March 22, 2010 How long has it been standing? Have you given it a good clean-out, oil/air-filter change and all? Blackened plugs = Could be your mixture is too rich, or your air filter is fouled. Here's a nice chart:
Cdingman Posted March 22, 2010 Author Posted March 22, 2010 it actually started doing it last summer while on a trip. i towed it home and found that the air box what cracked. i put a new one on last week and still the same. i cleaned the air filter and even ran it with out the filter and nothing different. a friend of mine has the sam bike and he had a similar problem and the dealer told him that the carb was dirty so the cleaned it and balanced it. i had a jet kit installed about two years ago after installing an aftermarket exhaust.
Ttaskmaster Posted March 23, 2010 Posted March 23, 2010 Check the carb manifolds - The stumpy black tubes going from carb to the cylinders. These do perish and crack open after a while. I'd personally just get it a comprehensive service and check-over. DIY or get 'a man who knows' to do it.
Cdingman Posted March 24, 2010 Author Posted March 24, 2010 yah i changed one of the carb manifolds last year because it was rotted and cracked. i guess i will just have to take it somewhere.
