    I hope not. I put 8k on my '13 GSW with no issues. 24k on a '15 GSA with no issues. And I have 12k on my '17 GSA with no issues. Please keeps us posted if you figure it out. This is not a problem that my dealer will be able to replicate.

    Typically, in autos, clutch judder is related to something loose in the drivetrain, such that it "gives" enough to allow clutch hookup, then hits its stop, causing the clutch to slip and unwind the loose component again, repeating again and again to get the bump-bump-bump-bump-bump effect. I had a loose shock on the front of one vehicle that allowed this via body roll. Loose suspension components, engine,/tranny mounts, and training arms or worn bushings also could do it. It would seem unlikely that is what is going on here.

    Have you checked the condition of your oil? Many have noted improved clutch behavior after an oil change. The wet clutch bikes require a bit more attention to oil choice. NO, I'm not trying to create another oil thread . :D

    I haven't experienced judder, but on a rare occasion I have noticed the change in engagement, usually it catches me off guard and causes a stall at a light.

    Yeah, that, I think, is cured with fixing the overfill on the reservoir. Happened all the time to me, never knew where it was going to grab. Drove me nuts. The only time I had shuddering issues was at the end of my oil change interval early on in mileage. Haven't had it since.

    Jim & I checked the reservoir a long time ago and it was fine. I have been curious to open it up again just to see what it looks like now, maybe we eyed it wrong.

    First I would like to thank all those that responded. In testing the clutch lever by doing a bunch of left and right u-turns in an empty parking lot, slipping the clutch a bunch to see how it performed, I find it is much improved. In talking to my dealer's service manager, he said that the shudder should not have any relationship to fluid level. So there is agreement there; however, I do get a bonus of better feel in using clutch lever by getting an over filled res level corrected. Fixing anything by way of the internet is always a crap shoot and the shudder issue is exactly that. Just because one does not experience the problem does not mean it does not exist. Good news is that it doesn't happen that often.

    One step closer, OP, glad it is improving.

    Same here. It was very disconcerting to see how your bike was performing behind that semi. I hope your dealer gets it 100% fixed soon!

    I have recently ridden VA 80 just south of US19, sections of TN 66 and 70 north of Rogersville, TN 31 and 63 between Middlesboro and US11. ALL had major climbing right hand switch backs. NO problems. Having the clutch in position one, closer to the grip and filling the fluid to the proper level "may" have contributed to this but can't say anything for sure except "absolutely no issue" with hopping. Contributing factors were: I was more aware of the situation and prepared for these turns, I got into first gear early and moved far left across the center line (no traffic, these are not heavy traffic roads), I did not worry about hitting the inside apex where it was most steep and if I went left of center I was prepared to head for the ditch on the left if a car popped up (most of these turns that was not a high probability event.)
    I was very observant of how the friction zone was engaging and played with it quite a bit. It did seem way more predictable. This may not seem to directly related but I have gone to church. LOL No their empty parking lot and practiced both left and right U turns feathering both the clutch and rear brake. This seems to be giving more confidence in slow tight stuff. For me, the problem seems solved, however I am making sure it is being noted by my service manager.
