clutch lever play: how much is too much?

            Spec is 2-3 mm at the perch pivot.  (1) I like more, maybe 8mm, so that the clutch engages while the lever s closer to the grip.  But the cable doesn t travel as far that way, so the plates don t separate as far.  (2) I also have a lengthened release lever (from Fred).  The longer lever decreases pull weight, but it doesn t rotate the shaft as far as the shorter stock lever does, so the shaft doesn t pull the lifter (rod) out as far, so again, reduced plate separation.

            I get no drag with this setup.  The only time it doesn t release is the first shift into first on a cold morning; the longer I warm up, the less it does it.  But the mechanic insists I m wearing out the clutch doing this.  Any thoughts?

With your bike warmed up, in gear with the motor off, are you able to push the bike easily by hand with the clutch pulled in?   If there is too much drag to push your bike, then you may need less free-play in your clutch cable.

Thanks Fred, that's another test that it passes just fine with my setup.  I think I'll stop fretting about it....

As long as your clutch is disengaged it doesn t make too much difference where your clutch lever is.  The only issue I can think of is that on some that still have the clutch safety switch active, this switch may not function if your clutch lever has excessive free-play and doesn t push on this switch enough.

This is weird:  the bike definitely flunked this "drag test" (for lack of a better name) with the extra play.   But that was new.  The drag was so severe that I can't believe I've been riding with it like this and not noticed.  And, when I adjusted it to spec (lower adjustment in the middle, 2-3 mm at the pivot), it dragged just as badly.  I double-checked the adjustment.  I'd already lubed the cable and checked for routing and fraying.  I took it off and compared it to a new Motion Pro one, could see no difference.  I installed the new one, which didn't help.
       The distance the cable pulls the release lever is 11mm (measured where the cable attaches to the release lever).  That seems plenty to separate the disks.  With the cable disconnected I tried to work the release lever by hand, hoping to see if its total travel was more than 11mm: the springs are too strong for me to do that.
       I'm at the end of my expertise (not a long trip).

I should have said it USED TO pass this test.  No longer.  Mike Huber's post reminded me of something:  Before this clutch problem started, I had the shop do the valves (next time I'll have enough time and courage to do it myself).  They changed the oil too, draining my T6 and putting in- I don't know.  They put enough in, per the slight glass.  Perhaps I'll put the T6 back in and see whether the clutch frees up, but it's hard to see how the oil could cause that much drag.

The factory specifies so much movement as measured at the end of the lever. ( Sorry for the imprecision , I m currently traveling without a KLR manual) But it s hard to make that measurement at the end of the lever. I ve found that a $0.25 piece (a quarter) makes a great adjustment gage if the measurement is made between the lever and the end of the clutch perch housing. You should have about a quarter s worth of freeplay before clutch engagement. A precision clutch adjustment gage for $0.25, delivered, is somehow apropos of the frugality of the humble KLR.
