[just4thecurious]

Im just curious if anyone who knows anything about baja mini bike engines before i rip the crank case open why there would be small pieces of grayish plastic in my oil every time i change it there about 1/4 by 1/8 by 1/4 this engine has the oil changed every 20 hours of use complete stock motor no less than month and a half old if anyone can help me it would be great also i notice when i go down hills now correct me if im wrong but once the bike is shut off should the centrifugal clutch be in a sense not engaged i cant cost with this bike with out the motor turning even when its turned off but i can idle it with out it moving so it does not seem like the clutch is stuck in engage mode thanks in advance for any help

The grey pieces of plastic were probably the remains of your governor. Did you bypass your governor without removing it? It could also be a broken dipstick.

The clutch should do what you say it's doing.

If it's that new, make a warranty claim. And if the engine is off, it should coast freely.

Is this a Mini-Baja model or a Doodlebug?

Its

A mini baja not doodlebug i just fished some more out of there this morning after a good 30m run yesterday im just afraid to open the crank case i dont know the tourq specs or anything for the jackshaft or the crack case plus i heard the cheap chinesse gaskets most times break and are impossible to get

The jackstaff shouldn't have torque specs. Just tighten it till it's tight the side cover should be tightened in a particular way where you tighten opposite bolts kinda thing, and do not overtighten, as the cheap casting can strip. It the gasket is shot, you can make one from card, like a cereal box, or buy one, as it is most likely a gx160/200 clone

Thats why I asked. The engines are very different. You have a GX200 clone. It is likely something may have gone wrong inside but lucky for you there are many inexpensive clone replacements out there if your engine is in trouble.
