Oil leaking out of hole on right side of cylinder?

4 posts in this topic

That hole is a drain for the spark plug area. When you get water in there it allows it to drain rather than build up. I doubt its oil, but more likely dirty water coming out and if it is oil, tighten up your spark plug.

Did you wash your dirty bike and spray dirty water up there? It's probably water. Taste it to be sure...

If you have oil coming from there, there are two possible causes

  1. The spark plug could be loose enough to leak combustion "goo" around it's base (not likely, unless you're burning a lot of oil)
  2. The cam cover gasket is leaking into the plug well
