Alright so a few months ago my dirtbike locked up for the second time i have drained all fluids. dont remember if there was metal flaking in oil filter or not it was a while ago that i checked. but i just drained the tranny fluid and a metal chunk came out about a 1/16" big and fluid was grey. i have just got done pulling the motor out of the bike and am waiting for my flywheel puller to come in before i get any deeper into the engine. if anyone has any suggestions of what it might be post it. and anything to watch out for when splitting the cases which i will be doing anyways cause i dont like the fact that there is metal peices in the engine that will mess up other stuff.
