I thought this was a dry (NO OIL) area?
It is dripping oil while parked from the bottom of the cover.
I removed the cover/stator and about a 1/2 quart of oil came out!
How is oil getting in there? bad/worn crankshaft seal?
ANYBODY KNOW???
I know why. When I had a 650R I ran into the same trouble. The space within the stator area gets pressurized due to the heat and causes the seal to leak.
Summers Racing had a very cool kit that relieved the pressure. He is no longer in business as far as I know.
It is very easy to do. Just use very small 1/16" hollow flexible plastic tubing. Punch a small hole through the rubber seal that your wires come through, run the tubing through the rubber just inside the stator cover, drill a small hole in your air box and route the other end through there, hold it in place with a dab of silicone.
No more leaks. I was lucky. My stator was wet. After the modification it stayed dry without replacing the crank seal.
Hope this helps....
