Clutch didn't disengage?

[TobyDanger]

Yesterday, after I did my usual routine and started my S2R800 in neutral on it's sidestand, geared up, and hopped on, I had something that's never happened before.  As I was sitting on the bike, I pulled in the clutch fully and stepped down to first.  I'm not exactly sure what happened because it surprised me so much, but basically the bike started to lurch forward and I think I either dug in my heels and it stalled or I grabbed the front brake and it stalled.  I stared down at it for a few second trying to understand what just happened and then carefully pulled in the clutch again (still in 1st) and hit the starter button.  As it was cranking over, it again pulled me forward about 3 steps.  I think I pulled in the front brake again and then it caught and fired up and the clutch released and it stopped pulling forward or maybe it stalled again and I just shifted into neutral and started over and it was fine...  I think I was just a little stunned and thinking that I was forgetting something maybe I was fumbling for the remote and just didn't have the brake in like usual, or?

The bike is very new still (my first Ducati and first twin), only about 400 miles and does sometimes makes a big "clunk" when shifting into first if I haven't ridden in a week.  What's going on here?  Is this "normal"?

Thanks,

G's 620 will do this from time to time if not ridden for a bit.    Plates sticking together?   

Don't know the permanent fix other than riding it more often, but dropping it into first while rolling it out of the garage seams to unstick them.   Just be ready for the wheel locking and quick stop despite the clutch being pulled in as you wheel it out.

any tech guys know what it's doing and how to make it stop in a more officially correct way?

I have heard of this on the wet clutches, usually earlier in day not ridden in a bit. IMO the oil may get stuck (yes stuck) as in a liquid vacuum, by that I mean where oil sticks between two plates holding them together briefly.


On dry clutches. most cases are from water rusting the plates a little.

Either way, there shouldn't be any damage, and it will probably only happen every once in awhile, if at all.

i would say, bleed your clutch line. might have air in it.

The same thing happens to me every once in a while. I've become convinced it's the clutch plates sticking together

My S2R 800 does the same thing, i'm pretty sure it is the clutch sticking.  When i get on the bike, while it is in neutral, I pull the clutch in and let it out a couple of times while giving a little throttle.  That seems to get the plates unstuck everytime.

The best way to make sure your plates aren't stuck together is to push the bike forward and back a few inches while in first gear with the engine off and the clutch pulled in all the way.  That method doesn't put any strain on any of the driveline.  Popping it into first when the plates are stuck is kind of hard on the gear dogs.

All of my Ducatis have had dry clutches, so I haven't had to deal with this problem.
