Just fully re-built top & bottom end, only need to change rear sprocket & fit chain & im riding again.
I cant seem to loosen 21mm rear wheel bolts to get to rear sprocket. do you have to turn them against each other, or are they right hand thread or something???

 

Anyone please, or could anyone direct me to a dirtbike forum?

ok i need a little more input here?i'm not sure what 21 mm bolts you're talking about.are you talking about the rear axle nut? if so, it'll come off just as any other bolt would.and if you're actually talking about the 12 mm bolts on the sprocket and hub itself.put a 12mm closed end wrench on the backside and a alan wrench of the right size and loosen them as you would any other bolt. RIGHTY TIGHTY/LEFTY LOOSEY!!!the rear sprocket bolts come with loktite on them from the factory,and thats why they are so hard to take off.good luck.

 

thanks guys,
Sorry I think it was a 25mm axle nut I removed, but Ive tried & tried to pop the axle out.
Tried spray lube, hammer & wood & still no joy.
Any tips??
