A while back, I was having the dealer take care of something I didn't want to tackle myself. As part of their "courtesy check," they pointed out that my clutch cable was leaking slightly where it enters the cover on the right side of the bike. Slightly being the key word here. I made a mental note to keep an eye on it and for some reason I started thinking about it more the other day. I've read all the Self Help Tips and it sounds like the first thing to do is simply to replace the O-ring. Seems like something I can do easy enough. I also did a forum search and came up with this interesting post from PetieJ: Not saying that this is your problem, but I thought I might mention this as it has to do with the clutch cable leaking oil. Make sure the breather tube for the tranny is not plugged. If the tube becomes plugged, pressure will build up in the tranny when it gets hot and it will force oil up the clutch cable. I have seen this happen several times on older bikes. However, this was in a thread about a 2000 Sportster. Read through my manual and examined all the pictures I could find and couldn't find a single mention of a breather tube on my 2008 Street Glide. Is there a breather tube somewhere in the clutch/tranny of my TC96 6 speed? If so, where is it? Anything else to consider besides starting off with replacing the O-ring? Anything else I should consider doing or checking while I've got the cover off to replace the O-ring? Thanks!
