I rode pretty hard for a few minutes and when I returned I found oil sprayed by the chain on my fender. Then I noticed it was bubbling and dripping from my front sprocket. It seemed to only do it while and right after I was riding, not a constant thing. What could cause this and how concerned should I be?

 

there is a seal behind the front sprocket that went bad.... I would fix it before you ride again.... The seal itself is only around 15-20$...

But if it blows all the way through while your riding...your going to lose all your oil and not be a happy camper.

 

Thanks for the info, I'll be stopping by the bike shop today.

 

Say-it-fmf,
What's the easiest way to remove chain fly-off from your swingarm and surrounding areas?
thanks
