Yeah, what MarvTravis said. When you release the clutch lever, the plates are allowed to come together under spring tension. When you pull it, you're separating the plates, against spring tension.

As the friction plates wear down and get thinner, it can get to a point where they are no longer fully in contact even when the lever is fully released -- tension on the cable is holding them in the "friction zone". This causes slippage and extremely rapid wear.
So rapid in fact that a few dozen miles of this under load (e.g. in the mountains!) wears it to the point where you're not getting any power at the back wheel.

Loosening the cable should allow the plates to come together. They'll be quite worn and will need servicing soon if not immediately, but it might get you where you need to go.

Note as curve addict suggests, this is for mechanical linkages only. Hydraulic clutches don't exhibit the same wear characteristics because when there is no pressure being applied at the master cylinder, the slave cylinder that operates the pushrod will allow the operating lever to return fully. So it's basically self adjusting for wear.

I don't know why it bothers me so much that the basic operating principals of a clutch has to be explained.


But it does...

While it has been alluded to there are usually two adjustments. One on the handlebar (cable operated) and one on the end of the clutch pack rod itself. I purchased a bike on the cheap because the clutch was slipping. Got it home and about 30 minutes later had the problem solved by adjusting the clutch basket rod. A lot of people do not know there may be two adjustments.

The Husqvarna TE610 and probably SM version came from the MV Agusta factory with the clutch pack rod misadjusted and neutral is difficult to find at a dead stop so folks would have to ease it into 1st just before coming to a complete stop. Pull the cover, adjust the screw so things are flush, put the cover back on and viola!

Eugene

if it were me, for that $200 i would have got towed to Eugene (or Springfield) to a shop. You're only about 30 miles away. I would personally not go to Bend but that's me. Eugene = much larger town, more bike shops. I don't even personally know of any in Bend.

my thoughts precisely. why would you push your motorycle 15 miles on a clutch that isn't working? Match your rpm's with shifting, it'll go in (and out) then ride til the next town (better yet, turn back to Eugene, where there are ample bike shops and even just people that could lend some experienced advice) but pushing it half way to Oakridge ,then getting a tow for the rest of the way to Oakridge? on a bad clutch? Perhaps this is a much larger problem than just a clutch.

edit: but then again, you said it just started slipping. so I hope that adjusting the clutch helped. How's it now? what was your diagnosis? What was the cure?

Just walked past a VTX1300 parked on the street six blocks from my house so of course I looked it over. No sign of a fluid reservoir by the clutch lever, just a big ole cable swooping away and out of sight. I suppose I could have looked it up on the intarwebs but that would have been too easy.

So yeah, judging by the symptom described, the cable's been in need of adjustment. The rule is usually to maintain a few degrees of play at the lever, maybe 1/4" measured at the lever tip, and if you don't have that, it's too tight and this is what's going to happen.
