Thank you MVAgusta.net, you guys helped me find (and fix) a scary problem with my new-to-me 2017 B3 800! I don't know enough to know what other models share this clutch assembly, but a dash of common sense saves the day.
When leaving a light a little faster than normal, my clutch would grab hard and unpredictably so bad the front wheel would come up! Dang that got my attention quick!
I found this thread on it:
with someone hinting they knew the fix but unwilling to post it? Ugh.
and this thread:
and this one with a great pic!
that got me a little closer to whats going on.
Sure enough the service manual shows the sharp outer edge of the anti-judder spring facing the clutch steel instead of the ring on the engine side it's supposed to seat against. Negating the wear on the clutch steel from it being installed backwards like the manual shows.
Thankfully, clutch removal on a B3 is an easy 10 min job at most:
On the side stand, so you don't have to drain any oil.
Remove 3 torx bolts from the slider and pull it off.
remove the torx bolts from the cover (don't forget theres one hiding deep in the back!) and pull it off straight. Theres alignment pins back there.
remove the 6 clutch springs and pull the clutch pack out. A magnet or 2 dental picks make this easy.
I found my clutch plates and steels to be in absolutely MINT condition, which leads me to believe it was just replaced and a dutiful tech either 'replaced in the order of removal' or 'followed the manual precisely' which I certainly wouldn't blame them for doing either. But tracing an issue opens your mind to really looking at every piece.
Well, the punchline is that I flipped the spring around so the sharp edge is facing its seating ring and immediately solved the problem. WIN!
Disclaimer: If you are a "Factory can't ever make a mistake" or "LIABILITY!" type of person, this fix may not be for you. But it is a "fix" and not a "mod".
Took a rip to the top of my favorite one-way road that drops all the way to the Pacific Ocean and had such a great time I did it three times
Now all I have to do is spend 4 hours cleaning brake dust off the wheels, Arrgh! Who treats a beauty this way?

2010+ F4 Grabby Clutch (possibly other models too)
Just a quick question, how many F4 owners have found the clutch grabby? i.e at traffic lights if you use some revs for a fast start, the clutch will suddenly stop slipping and engage promoting an unintentional lurch wheelie etc. Saw another F4 bite the dust today doing (attempting) a fast...

Clutch Release
I can't seem to find any posts about this problem so here goes. My 2016 TVL is very sensitive when I try and let out the clutch from a complete stop. If I don't very gently and slowly let it engage, the machine acts like a bucking bronco. Before I call my local dealer and engage the service...

Clutch damage
I am looking for someone who has knowledge of the slipper clutch in the Turismo Veloce. I recently had the clutch TSB performed by an authorised MV dealer and am now experiencing problems with clutch engagement. If I try to pull away quickly or up a steep hill the clutch slips, grinds and then...
