[Elite07trx]

ok i started my bike for about 30secs and now it wont stay running. It turns over. Nothing aftermarket. I really dont have any other ideas, i really need help.

also it doesnt seem like theres anything out of the ordinary, ive taken the carb apart and cleaned it thoroughly, ive checked the spark plug and there is spark.

Check Valve Clearances

My old bike did that exact same thing its your valves. just have them checked and fixed and you should be good.

actually i think its his air fuel screw, turn it all the way in then back it out till it runs!
