I unloaded my 04 DS650 at work today after a long weekend of riding at the dunes. As I was parking the bike I noticed what looked to be a oil leak that started where the starter motor fits into the crank case. I did not have much time to really look further but I am wondering what I need to look for. What could be the cause???

Thanks

 

There is an o-ring on the starter.. just replace it.. and you should be good to go.

 

I never can get that to stop leaking...... I just live with a small leak. I have replaced that o-ring and it takes about a month to start leaking again.

 

i never found the right o ring either, duneme it seems bought a new case to solve his leak, i put a little rtv sealer with the o-ring, problem solved. and i bought a whole case of o-rings to choose from.

 

Mine leaked for a couple of years as well. I got sick and tired of it. I install an oring that was way bigger (thicker) then the old one. Had to use a hammer to get the starter to go, but no more leaks now !!!
