KLR650 Oil Leak

For the past two/three weeks I've been fighting with a very slow persistent oil leak emanating from the left side of the oil filter cap.

I did my annual oil change in May and didn't have any problems until late June so I'm really confused as to what could have caused it. The bike is a 1995 (A9) with just under 7k miles.

When it started, I noticed the bike was leaving about a half dollar sized drop on the ground. I've got it down to about a dime now. Seems to start after the motor warms up and starts dripping after being parked (motor off).

Things I have tried...

- Rubber oil filter o-rings (three of them from two different shops)
- New oil filter
- Emptying some oil to middle on window
- New oil filter cap
- New oil filter cap screws

Next step is to cut one of the rubber o-rings down and mash it in there with another full o-ring to create some additional pressure on the seal. Gasket maker is out of the question! Other than that, it's off to Vickery's service department.

Nothing more annoying that not being able to ride with an otherwise perfectly good bike sitting in the garage!
