125cc pitbike cutout

[Johnpaulcurtis]

I got a 125cc pitbike that cuts out under a load In all gears. Ive tried adjusting the carb, i sealed the intake at the carb and head, new air filter, new plugs(even done a plug chop), rebuilt the carb, and still no improvement. Please help!

First of all check for proper ground. I have had numerous issues when using the stock stator gorund, now I always use frame ground to be sure .
