    Hi, I just got my bike mounted with a Starfire GT 4 and it worked great for the first 2 weeks but on a ride yesterday it just quit on me. It sounded like it ran out of gas but I have a full tank. I took off the carby and it was fine, full of gas and the float and seal seemed to be ok. Any other suggestions on why it stopped?

    Next thing to check is spark.

    Tried to post this earlier and it seemed the site had problems...So here I go.

    Same thing happened to me in just 3 days. Found the problem in less then 5 minutes....was the coil..$10.00

    No spark..testing procedures

    Same thing happened to mine. Remove plug
    1) Like said check spark using plug, if none I use my finger (redneck test). if none >>>>>
    2) Open coil cover up and look for short especially white wire if ok >>>>
    3) Check other wires for short all the way to CDI if ok >>>>
    4) Disconect both coil wires. Lift bike, spin rear tire while using a meter or test light to see if coil is putting out (white wire to ground) (7.5 VDC) if none replace coil about $10.00..If voltage..>>>>
    5) If kill switch is connected then disconnect. >>>>
    6) If kill switch was connected then repeat starting at step (4) >>> then onto (6)
    6) Voltage from coil, no shorts, no kill switch connected remove coil wire from CDI (it is twisted onto a screw) and check for spark (this wire needs to be replaced anyway..it's c**p). If you have VDC replace wire if not replace CDI.

    Sounds duh, but..
    Make sure the small wires from the engine to the cdi havent come too close to the exhaust and melted/shorted out to it. Happened to me! Drove me nuts for about 15 mins. Then I realized it, smacked myself in the forehead for forgetting to ziptie them to the frame. Off I went.

    Just to be sure, chech the flow out of the gas valve. It should drain the tank in about 2 minuits.
