    so i have had this bike for a bit
    1 it started to make a poping misfiring sound i thought it was my mixture so i added a bit more gas to the mix worked
    2 after a day it started acting up agin but instead was making a drowry moan like it was flooding ? or not geting gas so i blew out the carb and it started to work agin for like 15 minits
    3 now all try and start it and the motor will kick in but just on an adile if i pull the cluch to get to a idling stand point the engine stops instantly and if i fiddle a little bit i can get the motor to work for 5 minits around the block but its making poping backfiring sounds the whole time and it wont go to fast till it finaly cuts out agin

    trew all this i have had the spark plug looked at "not replaced"
    i have replaced a fuel line tho with i have opened the "crank case"?? so maby thats were an air leech
    is so if some 1 wants to help me with this tell me what to do all go do it and tell you what happened i figger i would stop screwing with it befor it reely breaks :-||


    Help i have a few DUI's and its the only thing the courts will let me drive

    Spray carb cleaner or wd-40 around the engine while you have it idling to look for air leaks. You'll either hear the engine cut out or rev. Look around the carb or intake, as they are the most likely culprits.


    Also most states require at least a drivers license to ride a MB. Although most police don't hassle riders.

    I wouldn't randomly add gas to the mix or tank, that asking for more problems.

    Water in the fuel?
    Tried a new plug?
    Checked for air leaks as suggested above?
    How does it run if you keep the clutch engaged once it starts?

    zagin called me earlier today and i suggested he come here with this, because ive never heard of a motor dying when the clutch is pulled in....thats a new one.
    he DID say the plug 'wobbled', so a loose plug doesnt help anything. but that wouldnt kill the motor when the clutch is pulled in.
    i,too, recommended he spray some carb/choke cleaner around the engine to check for leaks.
    did you do that?

    EDIT: joe...he says it runs like $hit, pretty much all the time it will run

    How old is your gas?
    Maybe the key has sheared off and it's out of time?

    I'd go with a new plug, and some fresh new gas/oil mix, check for water in your tank, and also behind the left side cover.

    zagin,

    You said you've had this bike for a bit...How long is bit? several months?

    If so I'm going to WAG, ( wild ass guess), this one and say that your CDI is on its way out.

    Good call Joe!

    It may very well be a combo of things.

    I'm thinking CDI because of the intermittent nature of the problem.

    The main jet tube is screwed to the bottom of carb. Remove the 2 screws that hold the fuel bowl to the carb if the jet tube is off it will be swimming in bowl with the float. I had one give me problems

    try turning the idle screw waaaaay in...just to keep the motor running while you spray around checking for leaks. way in.
    EDIT: ensure your wires are well-connected, and have you checked your spark?
