'14 1199 R /w Ducati Performance GP shift sensor

OKAY! Now we are getting somewhere, but still no fix. I took Phl's advise and took the spring out to see if it was bound up and I found a rather weird case where it operates. EVERY picture of the Ducati Performance GP shift sensor for the 1199 shows the large nut butted up against the sensor housing but the only way I can get the plunger to pull and the dowel to trigger the sensor is by backing the dam thing out half way. If I close the nut like MANY other pictures show the thing is locked almost like the spring is all the way compressed and locking that dowel back. Here are some good pics:

The way it was on the bike and how it is in many other pictures I've seen on the web, that dowel does not move forward at all to activate the switch, not even if I put it in a vise and pull the sucker:



If I back that nut out this far I can get the dowel to pull forward when I pull on the rod and it will go back to normal (in theory operating properly):



Everything taken apart for the visual, everything look in order? My first time looking at the internals:



Phl, this is what the stock spring looks like right?? WD40 didn't help by the way.

Dude, your trouble shooting skills are horrible.

Eliminate the part as a problem. Don't attempt to diagnose what is wrong with the part until you KNOW it is the part. Its MUCH more likely to be an electrical problem than a mechanical problem, with the only caveat being the linkage could be backwards.

Install the standard QS, and report back.

ok, ill install the stock unit but it'll be useless, its rock hard with no movement in the dowel. It's going to be the same problem. I'm not sure what its going to tell me, I don't think its electrical, its pretty clear its mechanical no?

Its a spring and a rod. Not a lot can go wrong there, and without any obvious defects, I wouldn't dwell on not being able to move it by hand. By design it should be very hard to move. The odds that you have two different parts exhibiting the exact same "symptoms" isn't at all probable.

With the micro switch exposed, but the bike on a stand and start it. Give it some revs and hold it. Depress the microswitch and see if the engine responds.

Are you sure the lever on the transmission shaft is installed correctly? Can you take a pic of the installed GP shifter?

Here are some pics of the GP shift sensor and lever, sorry for the angle, I don't have one head on. The marks are lined up exactly as the instructions say, which is to flip the lever and line up the marks.

Try actuating the microswitch with the engine running.

I will do that tonight and report back, thank! I assume in gear and not in Neutral?

ok, I put bike on the stands..put her in 2nd gear with the engine running and rolled on the throttle lightly and held it. I then pressed the orange plunger sensor and I heard the engine bog down a little when I pressed the button (did it multiple times).

So now lets troubleshoot the mechanical portion with the spring?

Are you sure the shifter you're using is the reverse quick shifter? Because it looks an awful lot like my stock quick shifter.

All this discussion made me go out to the garage and dig out my DP reverse quick shifter that I no longer use since installing DP rearsets. The DP reverse quick shifter has a completely black head, and it doesn't have the big nut you removed to get the spring out.

Here's a picture of my DP reverse quick shifter:



Also note that the reverse quick shifter compresses to trigger the micro switch. The stock quick shifter pulls to trigger the switch. The one you have pictured clearly pulls to trigger the switch. I think that's a stock unit, not a reverse unit. That would explain why it doesn't allow you to shift when set up GP, or vice versa if you're using the reverse QS for a right side up shift pattern.

I also had to put nearly all of my body weight on my reverse quick shifter to get it to compress and trigger the switch. The unit is in fine working order and I clutchless upshifted all the time without rolling off the throttle.

There just not much there.

Is the bike otherwise stock?

Has anyone else ridden the bike and duplicated the problem?

What is the total length, center to center of your assembled shift rod? Could this be an adjustment issue? Have you attempted in the past any length adjustments to change the position of the gear pedal?

See attached pic...

EDIT...Nevermind. Its not a GP QS.

OK, I must be going insane or something. Here are both rods, the bottom one is the one I've had on the bike /w the shift arm in GP shift configuration, and the one we've been troubleshooting. This is the way the previous owner rode it at the track in with GP shift (I do not think there were any changes between his track ride and selling it to me, but I'll ask). The top unit should be his spare part from when the dealer installed the GP shift rod, the dealer even marked it as STD shift 1199R (according to the red tag anyway).

I totally understand what you're saying and your picture makes sense, but can you put this to rest, Which one is the GP shift rod and which is standard? haha

According to people selling on eBay you are 100% correct and the one we've been troubleshooting looks stock and std shift.

and the kicker, the Ducati instructions for the reverse shift sensor show the BOTTOM one in the pic above is the reverse sensor haha. What's going on?

The top one is the GP shifter you want.

You can reason this out for yourself. You know which one is push and which one is pull (you can see that when you remove the plastic caps). You can also see that when you set up for GP shifting and you push down on the shift lever, the quick shift linkage wants to push the lever on the transmission shaft. Pick the appropriate quick shifter.

Chris.

ok, I'll install the top one in the pic tonight and test it out. I talked to the previous owner also this morning, he made no change in the quick shifter sensor between his track days and selling it to me and he always used GP shift and the quick shifter worked.

But you are correct mechanically you push the lever down ad the rod wants to travel toward the front of the bike pushing the plunger in.

Anyway, I'll give it a shot.

As I've mentioned previously, you don't need a quick shifter to do clutchless shifting. If the previous owner always backed off on the throttle when he upshifted, he'd execute perfect shifts all the time.

Thanks all, that was it! The previous owner had the stock shift sensor installed with the GP shift pattern arm flip. I talked to him again and he said it was totally possible that he was just rolling off and shifting perhaps (at the track), he never really noticed haha Luckily he had the reverse quick shift sensor in his parts box and also gave it to me.

Took her for a quick ride up the block, couldn't get her going that quick of course but its working as intended now

Awesome! WFO shifting from now on!

EDIT: Simply replace the Gear Position Sensor. Everything works great now!

Sorry to revive this thread from the dead but:

I have been using the standard Ducati shift-rod with the flipped arm for GP shift on my 2014 1199S. Lately, the dash was bugging out with an error and the lights flashing at the gear position indicator.

Figured the sensor on the QS and running in race mode finally freaked out the computer. Ordered the Ducati Reverse Quick shifter since I can't just buy the potentiometer or micro switch.

Running in in 195 Low and not race mode seems to have helped clear up the errors on the dash and let the computer learn the positions again.

I will install the reverse rod with my CNC racing rear sets and see what develops.

how do you replace the gear position sensor? did you have to order the part from ducati?
