As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Nasty oil leak, What's this hole for?

K, I got a crapload of oil all over the place riding the bike home from a trip. So after tracig the mess, I took the cover off the left side and found this hole leaks copious amounts of oil when the enigine runs.

Anybody know what's up? It looks like the hole was supposed to be there, so did I loose a plug, or some gasket farther up inside?
 
That hole is a drain for the starter cavity. Most likely the large O-ring on the nose of the starter has failed. Easy fix. Pull the starter out, replace the O-ring, reinstall. Easy job other than the lack of access.
 
Starter is the first suspect, could also be cam chain tensioner

That doesn't sound like any fun.

I was looking at that thing and wondering; Why would they put something your not supposed to mess with right out there with an invitingly knurled adjuster on it? I know how close I came to calling it an idle adjuster at first glance, it's amazing that I didn't just reach out and twist on it. I can imagine somebody may have futz'd with it at some point while it was for sale, though.
 
Ah, the Mystery Hole...

Yes, oil from the Mystery Hole is usually just the o-ring on the nose of the starter. Easily sorted.

Cam chain tensioners (even easier to fix) also can leak oil, but it's never more than a slow annoying seep.

The starter nose o-ring can really shove out a lot of oil -- never enough to hurt anything if you're paying attention, but enough to make every ride a greasy mess.

And whatever you do, please don't plug your Mystery Hole.
