Try draining your carb(s). You may have water in them or your tank. Also try puting sea foam into your gas to clean the carbs up. Read the directions on the can before pouring in though.

Backfiring and trouble starting


If you change the exhaust pipes, you have to sync the carbs (if you cant sync them, you have to change the carb jets), usually it is backfiring because the carbs are not in balance.

Honda CB250 will not start. It will turn over and there is fire on the plugs and when I look at the plugs after trying, they are "wet" with fuel. What am I missing?


Valve clearance or camshaft timing. If you have no clearance on the intake valves at top dead center, then you will have no compression = no start.

Check the igniter. Go back to the dealer and ask him to see one. Then go back and find it on your bike. Yamaha's usually have them under the seat, or left side. But I don't know exactly what year you have. Run the VIN on the frame under my tips and tricks is a web site that'll break it down for you.
