I have a problem that is giving me fits. The bike spits and backfires out of the exhaust several times before it will start. It don't matter if it is hot our cold outside. There is a gas smell surrounding the bike as this is happening. I have torn the scoot down and adjusted the valves to .003 intake and .005 exhaust so it is not the valves. I adjusted the carb air/fuel screw and checked for air leaks. I also replaced the fuel filter. It will slightly rev up and down at times. I can be driving along and it will be purring and it will go dead. It then will backfire and  a few times before it will start and run good till it does it again. It will idle perfectly for 30 min then go dead and the process repeats it self. I love this bike but it is driving me insane. It has 3150 miles on it. Could it be the coil breaking down and not providing enough spark at times?. I also cleaned the air filter. I am at my wits end. Any help would be greatly appreciated. |

It appears it may be getting gas from someplace else, Take the Vacuum hose going to your FUEL PUMP or PETCOCK(if the tank is above the carb and see if it is wet from fuel. Also check the ACV valve Vacuum hose, that is the SAUCER shaped Diaphgram near the top of the carb. Check that for gas in the Vacuum line.

I will report back on the results. All I want to do is ride. This bike is a blast to cruise on. I got to find the solution. |

A weird thing is that after checking the carb and carb lines as per alleyoop's instructions It done the same ole thing. I took it for a spin and really opened her up. Once I got around 65-70 mph she started spitting and backfiring. It done this for about 1 min or 2 then she just smoothed out and started running like a well oiled machine. That has been 9 days ago and the scoot starts first spin every time and runs like a champ. I had already adjusted the valves and changed the fuel filter and checked for air leaks and cleaned the air filter. Man this scooter could not run any sweeter right now. Don't know what happened. I am a happy camper now. It is cruising time.
