hey i had that happen, and i didn't have any strange noises, then i left to colombia, and when i came back my brother blew the engine in it, well the piston shot throug the motor i guess, and my dad sayed that was because i put the wrong oil, but i know it was the rigth one, then later he sayed it was because of the shavings, that it was going bad. i don't know much so don't belive me

 

You can't spell either!.........[img]i/expressions/face-icon-small-wink.gif[/img]

 

I've got metal shavings in my filter, on my plug and on the tank strainer. EVERY OIL CHANGE!

I think it's fairly common when racing hard.
