getting an oil leak..

Ok, first off, I have not done any looking in depth, but I am starting to get an oil leak.

I get a drip or 2 off of the front area of the starter.. what in that area can leak, other than sealing between the starter and the case?

yea, I know, I sound like a newb on this question, I am just looking for insight as to most likely places to look first.

iirc: There is a flat plate along with a flat paper type gasket up against the engine & behind the the starter mount (same diameter as Oil Filter).....and I THINK some kind of Rubber O-Ring (Quarter size).

Could very well be. The only other thing to watch for is that it's dripping from above onto the starter, then going to one end and dripping off there. If you're sure it's the starter, it won't take more than a few minutes to change out the o-ring during your next oil change. That's p/n 92055-1276 and should be about $5.

Anyone know the size for the starter o-ring?

Have had a small drip once in a while, but after a weekend of rides, I've got oil all the way down the right side on the pipe, engine, saddlebags. Pretty sure it's coming from the starter.

dont know the size of the oring off hand, but my oil leak ended up being the right side cover gasket, just above the water outlet, had 'pushed' its way out of the mating surfaces.

took removal of right cover to r & r it. not to bad of a job

Hey mtb, thanks for the heads up. Got down and looked at mine yesterday, and it's the gasket pushed out at the top front corner of the clutch side case. About 1.5" of the gasket protrudes out past the case, can see daylight between the strip of gasket and the seam of the engine cases. Will try to get a pic or two before I fix it.

I wonder if this is a common defect? It looks like it's always been that way, the gasket doesn't move like it's broken, it's like the gasket was the wrong shape at that spot. I guess I'll know more when I take it apart.

The heat shield on the exhaust looks like it's in the way, maybe the exhaust is bent. Looks like the pipe might have to come off to get the side cover.

if I recall, yes, the right exhaust pipe comes off (I know heat shield does), and the removable side of right side frame comes off as well.

yea, my replacement gasket didnt extend past the case at all, but my original did.

be careful of the o-rings in the coolant pipe, or you will be taking it apart twice like I did

Finally got around to replacing this gasket. Have pics but can't get them out of my phone yet. (edit: pic shown below)

At the top right corner, the gasket has always been out of place, with a gap you could see through. Can see the impression made by the cases clamping together, where the gasket was sealing in this curve, only 1/3 of the gasket was covering the surface of the case. From there the gasket was outside the case for about 3", in the curve at the top right. Could probably drop a dime through the gap, so about 1/16".

Can't say for sure the factory did this, but everything I've been into on this bike has looked all original. What I don't get is why it just now began leaking, and how did it not get water in the oil?

Ordered the gasket back in August, sometime around the end of Sept., I threw the new gasket away! Was thinking the gasket was in the garage and the envelope was empty. Wrong. Ordered a side cover and clutch cover gasket yesterday.

So much for my weekend ride. Mr.Bean strikes again.
