Oil leak

Post by stewartwayne50 »



I have a 77 GL1000 that has a oil leak. So far we have not been able to fix it. It really shows up when you punch it at 70mph. Any ideas where we should start looking?

I'd start by looking for the oil leak. Clean it off then look for where the oil's coming from. Best I can do with the info you've given.

We cleaned off the area and it does not appear to be leaking around the gasket seals.

We won't be able to assist without more info. Where does it look to be coming from? Right side, left side, rear, front or ????

It appears to be coming from the right side. You can see the evidence on the right exhaust pipe.

Spray everything clean with brake cleaner to get rid of any oil residue, then dust the suspect areas with talcum powder. It will take only the slightest oil leaking from its source to be immediately evident where the oil is coming from.

Pay special attention to where the tach cable comes out from under the fuel pump. You can probably replicate the leak (with the powder) on the center stand around 4k rpm. May see it at an earlier speed with the powder. The tach drive leak showed up on my right toe, I've got large feet.

If it is that, the oil seal is available, #31 here http://www.westernhonda.com/fiche_secti ... veh=131059

I couldn't get mine out, bought an elbow off ebay that fortunately did not leak. You're supposed to be able to pull it out by grasping the shaft and pulling.
