Recommended Posts

hey i bought a used thumpstar 125cc pit bike around Christmas i rode it for about a day it was running good and then i was ridding around in second gear and it bogged out and died. i tried to start it nothing. i then let it sit and tried it a couple hours later it started and ran for a little bit then died again. then i checked for spark and there wasn't any spark i tried it after awhile nothing. i then replaced the stator, ignition switch, coil and spark plug still no spark i also tested the cdi on another pit bike and the other bike ran better can you pls help me!!

Well lets see If you have changed all the parts and checked the CDI, I would verify the spark plug as good and go to T-Bolt's website and find out how to read out the stator to make sure you have it hooked up correctly and that you got a good stator. I would also go through the carb and clean it very well removing all the jets and using compressed air to make sure all the ports are clear.
