Welcome to the forums.

I'm moving your post to the Yamaha section. The folks in there will be able to help you out.

 

Should be able to remove the sprocket,possibly the bushing and pop the old seal out. Set up like most Japanese and Europeans on the sprocket seal.Even my old Honda is set up the same way. May have to replace the o-ring behind the bushing along with the seal if damaged. Plus wouldn't hurt to use a little blue loctite around the outer part of the seal the way Ktm recommends.It does help. Items# 41-46 on the parts break down.
