@shift4life125 haha nope (: pistons fine!

[shift4life125]

@justinyoface911 your piston is prolly gone now! cause if you sucked any of that mud it ..its prolly scored

[justinyoface911]

@shift4life125 no it was the airbox. filled with mud and bad air filter

Try cleaning the carb ,check reads and if you have spark than your good as far as the stator goes so it would be in the motor

most likely your top or bottom end , i hear 20 hours for doing top ends , but if you dont race or anything top ends can go longer , only way you'll know is to open it up.

mine bogged out in 5th & never started again , turned out to be my bottom end bearings locked up .
