The oil tube/hose that runs from the frame to the case under the clutch on the right side is leaking oil at the motor conection point. I took out the bolt and looked at the o-ring. It looks fine, no damage or cracks. The connector looks good and the case cover looks good. If I run the bike, shut it down and look at that point I can see the oil seep out about a drop every 4 minutes. I need to fix this and am going to install a new o-ring first, but have never heard of a o-ring wearing out. I havce had this apart several times in the last few weeks doing repairs to my kickstarter, but the ring is not damaged. What do you think?
