Road King inner primary leak
Anybody else have an inner primary leak on their Road King or other touring bike? I have 23,000 miles on my '05 and it leaves a drop every other day if I'm riding it alot. Already changed the drain plug and primary cover gasket, but no change. Seems to be oil on the inside of the primary but can't tell exactly where it's coming from.

RE: Road King inner primary leak
my '05 has about 40,000 and not a drop anywhere - best thing to do is clean it up really good with alcohol or brake clean, and watch it closely to pinpoint where it's coming from - maybe a paper towel on the floor to see where the first drop is hitting, then lookstraight up, might get you a little closer - gotta find it first, then work on the fix, don't take stabs in the dark, can be a waste of time - you might even put something on the area of the leak, like some wax (don't wipe it off) and this might help to pinpoint it also - cover everything under the whole area

RE: Road King inner primary leak
My 03 Road King leaked on the inner primary. It was the seal where the starter shaft went through the inner primary. Took the dealer twice to get the leak stopped. Everything has to come off. Pain in the a**. It would only leak a couple drops a week but started throwing oil on the belt.

RE: Road King inner primary leak
Are you sure it's the primary? I had a mystery drip like that too that was frustrating. Ended up I'd overfilled the tranny by a couple ounces and that was the source of my grief. The source was from somewhere on the inside surface of the primary area but i just couldnt tell where.
Now Iknow toput 22 ounces of fluid in the tranny when I do an oil change and haven't dripped at all since.
If you overfill it forces it's way out. Maybe it's as simple a problemas that if you're lucky.

My '07 RKC with 16,000 miles appears to be leaking from the mainshaft seal on the transmission side.

RE: Road King inner primary leak
I had the same problem. Is the oil dripping from the bottom of the primary directly under the clutch/derby cover? Shine a light down behind the primary where the transmission shaft comes through the inner primary. Is that area coated with a fine mist of oil, too? If so, then the problem is most likely the jackshaft seal, and the oil you're seeing is actually from the transmission, not the primary. They are notorious for leaking. The "easiest" way to get to the seal is by removing the outer primary, primary chain and inner primary. A royal pain for one little o-ring seal. I had the dealer repair mine...if it leaks again, they fix it for free!
