oil leak - what is this bolt?

[jsandidge]

I have developed a pesky little oil drip. Not much, but a few drops each day I ride. I degreased and sprayed powder. I seem to have found the source. There are 2 bolts on the underside of the case, behind the stator cover. The rear one looks to be the sorce of the leak. What are these bolts? Are they just plugs? Can I just unbolt this and put a copper crush washer on?

( I think) they bolt the cases together???

Drain bolt for the secondary drive? What bike is it?

[chuck hahn]

Secondary drain is under the small rear cover where a chain sprocket cover would be. thumbnail said 82 850

Case bolts

I do believe Chuck is right as far as case bolts. The main question is how to stop the leak?

[chuck hahn]

If its a case bolt it shouldnt leak unless the case sealant itself is failing..which is a very very rare thing to me. The sealer ( in theory ) should have been spread all around the holes in the halves to prevent just this thing.

Drain the oil into a real clean drip pan and remove the bolt. Squish some RTV into the hole and around the shoulder and tighten it down maybe???

Yeah case bolts. that is where GXSR7ED's leak was on his 750T, I pulled them out, cleaned them and applied a little bit of Honda bond on them. Pretty much stopped the leak.

Yes, they are definitely case bolts. I pulled both of them out. The front one that was not leaking looked as if it had a thread sealer on it.
The leaky one had no thread sealer and there was oil in the threads. I did put some RTV around the shoulder of the bolt. It appears to be working. We'll see with some commuting this week.
