Oil Leak
« on: September 07, 2009, 09:05:20 AM »
Having established that I'm the 3d least gifted mechanic in this Forum: Haven't had my R65 on my little lift yet, but the kickstand is totally covered with grease, and a little puddle of clean oil forms under that side of the bike, within a day or so. Pretty much in a line under the petcock, but I can at least discern that it's not gasoline.  Any of you motosurgeons have a good guess on the source? Engine or tranny?

Probably either the pushrod seals or the oil sensor (aka Switch, Commutateur Interruptor).  The oil sensor switch is an easy fix, but the pushrod seals, not so much.  Clean things up really good with a carb cleaner, being careful to do that in a well ventilated area, then go for a ride and look at it when you return.  That will tell you which one or both.

It could also be the transmission shifter seal.  Like Bengt said clean up all the oil and go for a ride and check it when you come back to see where the source of the leak is.

Not a really bad way to spend a holiday Monday afternoon!

Go motorcycle riding for an hour. Park the bike on the centerstand, in the shade, somewhere a breeze is blowing. Crack open a favorite adult beverage and watch for a oil drip to show up. If Patsy asks you to mow the lawn, tell her you're too busy working and following professional advice.

Hope this works for you, Burt. Doesn't always fly at my place.  ;)

Try cleaning the suspect area real well, dry it off and coat the whole area with baby powder. Then take it for a short ride and inspect it. The leak will be a lot more apparent. And it will smell fresh.
Good luck.
