Did you get another rubber gasket or was it the thicker gasket material?

After I had some work done on the bike, I noticed that mine was leaking from the inspection cover and the drain plug underneath.

I replaces the thin rubber gasket with the thicker gasket, and replaced the rubber o-ring that was on the drain plug.

No more leaks.

I have always put a quart in the primary, and I was wondering about putting a bit less, and it looks like you agree?

By the way, 90,000 miles since 06... I have to give you rep for that.

My '06 seemed to weep primary oil from the inspection plate, when I put 1qt in it. It's hard to get an accurate fill level without having someone hold it up for you. Cleaned up the gasket on the inspection cover/hole and now I only put 28oz in it. I figure when I change it, seems logical that the primary still has a few ounces in it.
