guys can you tell me how the outer bearing and seal on the sprocket /engine cover gets its oil. I did a chain and front sprocket change ..with seals and there was oil in the outer bearing..not sure how it made its way in there...thanks

The oil travels through the output shaft (the shaft with the sprocket on it). It comes out the end and lubricates the bearing and drains back to the crankcase through a hole in the side over.

Interesting. Then what is the fix? New gasket somewhere? Just tighten stuff down? Loose screw? One of our Tdubs has an oily film over the front sprocket area.

Output shaft -- inner seal and outer seal; shift shaft seal; new gasket for the side cover; drain plug isn't leaking -- and you still have an oil leak? Are you sure it just isn't cast off oil from the chain? Check the neutral light switch. It is down along the bottom and the plastic insulation breaks down and it starts to drip -- it happened to one of my TW's.

It is hidden under the left side cover. Red arrow points to it. If you lean the bike over you may be able to see it and see if it is leaking.
