well today i was driving the shee and it went like a grinding sound on the right cyclinder .. i pulled the spark plug out and there is metal on it . so next i took the head off and the piston looks fine kicked it over looked fine. then i went to kick it again she will not kick for anything.So what can be wrong ?

 

hmmm maby somthing in your bottom end was kocking and finaly let go

 

If it sounds like knocking the main bearings may have shattered in the crank and small pieces are slipping though to the top end. Possibley the wrist pin bearings too.

I had the knocking then the knocking got worse. I pulled the motor, slpit the case and found that my bearings letgo. Alky power had alot to do with it.

You can find cranks online for around 350 or so bux built stock. Good luck.

 

when i was rideing it though it never stopped i turned it off . it didnt turn its self off . it was running on the left cylinder fine just not the right the right sound like knocking / rattling
