Oops...countershaft sprocket came loose


Took the bike out to the supermoto track this morning to break in the engine. Looks like I forgot to bend over the tabs on the countershaft nut. It didn't come all the way off, but... oil shot out all over the place...ruined my rear tire.

My question is could this have caused damage to a seal or should it be OK now that I've tightened it up?


Honestly, I would think the seal has been compromised. How long did you run it loose?

just replace the seal. its very easy to pull off and put a new one in..

btw how did you wreck the rear tire?

ooops forgot you said supermoto.. now i no why your tire is wrecked

Thanks for the info....it was a rookie move.
