Oil leak

Postby 5oakseric » Fri Sep 23, 2011 11:18 pm



I've got an oil leak. It took me a while to locate it. I'm pretty sure it's leaking out around where the speedo (or tach?) cable goes in next to the fuel pump. I thought it might be seeping out past the seal where the fuel pump mounts but I check those bolts and they're tight. Anyone have this issue? Easy fix? I get that occasional wiff of burning oil as it drips down inside the exhaust heat shield. I hate that smell. It's the smell of a problem. I also don't understand how to adjust the clutch cable. The clutch was catching way late. The hand lever almost full out. I adjusted it down by the lever on the transmission so it's much better. Now I have slop in the hand lever and I have adjusted that out to the max. Until I get the manual you folks are all the help I have. Thank you in advance, Eric

Have a look at How to replace your clutch cable - it has instructions on how to properly adjust your clutch.

As for the oil leak, there shouldn't be oil in that area, so I suspect you may have a seal leak on the eccentric cam that drives the fuel pump. Have a look at Replacing your fuel pump and you can see the insides of where the oil is coming from on your bike.

tWO posibilites..leak from clutch cable port..if so you needa new o ring in there..the other is the "gasket" at the attachment point on the head..it's hard gasket..not very flexible..adding sealer to it may fix your leak.

Ya know,I thought about this a lot.So I went on the hunt.I couldn't find in any print anywhere that it shows a seal on the rear of EITHER cam :?:

I also rooted around my spare head assembly and found that neither of the 3 gl1100's had that seal on either rear part of either head. :geek:
As a last ditch effort I looked at the cam itself.I found that the tach drive gear is much larger than the cam shaft that the bearing rides on so I can't see how a seal could be installed anyway.

Looking at the mechanics of this,I can see that a seal is not necessary as any oil that would leak into the cavity would not only lube the pump lever and the tack cable,but the excess will drain back into the head.
NOW MAYBE I'M DEADWRONG. An please let me know.

a common place for the fuel pump to leak is where the tach cable goes into it. when you remove the mounting bolts for the fuel pump, the tach cable will come loose from the pump. there is a seal in the base of the hole where the tach cable goes in that sometimes goes bad, and oil will leak up past it. you will have to dig it out of that hole with a very small screwdriver. seems to me it was a $5 or $6 part on bike bandit. i had an interesting thing happen with my fuel pump...replaced ALL of the seals ("isolators") as honda calls them and it still leaked...it was leaking oil, not gas. i ended up buying a used fuel pump off ebay, buckled it all up and since then, no leaks! don't know if there is a crack in the old pump or what. i prefer to leave well enough alone, though. so far, no leaks...i'm happy.
