Holding in clutch at stoplight is user error?

If you two finger the clutch you never hit the microswitch. Interesting.

The cylinder cut will also occur if you are in neutral, throttle is fully closed, and coolant temp is hot enough (3 bars on the gauge or roughly 175 F)

I wonder if I can put some tubing on the actuator for the microswitch on the bottom of the clutch lever to get it to engage on a two finger pull. I could have sworn my Evotech levers had that but I switched to the TWM ones.

What do you mean by a two finger pull? Shouldn't matter how many fingers you're using, the micro switch usually actuates right as the friction zone begins.

When only pulling with two fingers the max distance the lever will be from the grip is that of your remaining fingers plus whatever your glove thickness is.

This is different than a full four finger pull which will collapse the lever all the way to the handgrip.

The microswitch doesn't engage until the lever is very close to the grip, much closer than you can get it with a two finger pull.

That's odd. The micro switch on my V4 is engaged significantly earlier than that, roughly halfway through its travel, which is right where the friction zone is for me.

Really? Well ..... Maybe mine just needs some adjusting.

Can you post a pic which would show the lever position when the switch is engaged?

Adjustable levers (reach and bite) give a lot more control over where and how everything works, including the lever position vs microswitch. But if the switch is loose or rotated to one side of available play it may cause more lever travel to actuate.

The adjustment of the lever doesn't effect when the microswitch activates.

I just bent the little micro switch arm to the other of the peg...so it never actuates... anyone seen issues with this? I can pull away from stop more easily now...1199

That switch is a menace. I’m sure it does more on the 4 than it does on the 2 but on the 2 it enables in gear starting and changes fueling at idle. I never installed it on the lever. I have a momentary push button switch directly in back of my starter switch. If the bike ever dies and I have to start it in gear, I just pinch the two switches. No brainer as you have to hit the starter anyhow.

Update to the original post.

I had the clutch master cylinder replaced under warranty at about 3000 miles. It seemed to solve the problem.

Now I have hit 6500 miles on the bike, and the problem is starting up again. I pull in the clutch lever, and after a few seconds it starts to lose pressure, so I have to keep pulling it in farther and farther to keep the clutch disengaged.

Took it back to the dealership, and they are doing another warranty replacement of the master cylinder. Its been 3 weeks since I dropped the bike off. I called today to get a status update, and they said that Ducati has discontinued the original part, and have superseded it with an updated version.

Original part# = 63040951A (63040951A - CLUTCH PUMP)
New part# = 63040952A (63040952A - CLUTCH PUMP PR 15/19 EVO 1 SWITCH)

The details on what has changed were not provided, but I am hopeful that this new part solves this issue.

Intresting. The ones for the 2021+ Panigale that were supposedly the self-bleeding ones from the SL changed too.

Old.

63040931AA - CLUTCH PUMP

New.

63040932AA - CLUTCH PUMP PR 15/19 EVO 1 SWITCH

I’ve got a 2022 SFV4S and haven’t had any issues, but she’s still young. The 2022 parts manual lists the old part, and so I wonder if mine has the discontinued part or the new part. The bike was manufactured in June of 2021 as a 2022 model.

Will you post a few photos of the new clutch pump (master cylinder) when you get your bike back? Thank you, and I hope this solves the issue for you!

After being at the dealership for a month, I got a call today that apparently Ducati is denying the warranty replacement. Even though the original part has been discontinued and replaced by a new part, they will not honor the warranty. Kind of makes a warranty useless.

I have a call in to Ducati North America, but based on what I have read online regarding their customer service, I don't have very high hopes.

Bike is probably going up for sale as soon as I get it repaired. My first and last Ducati.

Hate to say it but its probably for the best, sounds like your dealer is "difficult"

I find it hard to believe that its the clutch master, from the board reports clutch problems are most likely slave related and even then as I previously mentioned all my issues on the 1299 melted away when I flushed the system and changed to a good quality fluid. The heat turns the fluid black pretty quick and may contribute to the problem Even then it was the occasional 30 second burp of the master bleed nipple to make it 100% again.

Why are they denying it? I'd maybe try putting up a fight. Don't be a jerk but don't just accept the answer.

The dealer (Mountain Motorsports, Roswell GA) was not able to give any reason as to why Ducati denied the warranty. I did call Ducati North America, they are researching the issue and are supposed to be calling me back this week.

But I did get some good news yesterday. There is a very highly regarded independent Ducati shop in the area (DucShop.com). They are not factory authorized, so no warranty work. I called them to see if they could take a look at the clutch. Turns out DucShop has been purchased by another local dealership (Wow Cycles, Marietta GA) that just got a Ducati franchise. I spoke to the owner of DucShop, and all their equipment and personnel have moved to Wow Cycles and they are getting ready to start factory authorized repairs and warranty service in the next week or 2. They are going to diagnose my clutch issue, and they seemed optimistic that they can solve the issue and potentially get Ducati to honor the warranty. Fingers crossed.



I am very happy that I no longer have to deal with Mountain Motorsports. Its been a painful dealership since day 1. Example: At the 600-mile service they released the bike back to me with no oil in it. They had drained the oil, but forgot to refill it. I started the bike to drive away and luckily noticed the low-oil warning light and killed the engine. Bone dry. Then when they did refill the oil, they massively overfilled it.

I had the overfill experience with my dealer but I might have had a strong word or two for the dealer if they totally forgot to put oil back in it.

That's a pretty big epic fail.

If my dealer released my bike back to me with no oil in it and I started it, even for a second, the dealer would be taking that bike back into their inventory and giving me a new one or giving me a reaaaal long extended warranty..

Seems like a lot of dependence on the dealership to do simple tasks these days. What happens when the warranty runs out? Sell the bike?
