Unfortunately, after the new customs regulations in Turkey, they are charging significant taxes on items over 30 euros. Until a few months ago, the limit was 150 euros, and a year ago, it was 1500 euros. Our dealer sometimes places orders on a whim; I’ve seen them make us wait 3 months even for the valve shims needed for the Desmo. We'll see, maybe they had stock available, as the same product was used for all L twin versions between 2016-2019.(Multistrada 950-950s-1200-1260-Pikes-Diavel etc) By the way, if you ever visit Turkey for travel, let’s get in touch. I’d like to buy you a beer as a thank you. Cheers!!
The latest update: The dealer has the MAP sensor in stock, but the shipping didn't make it for today. It will probably be shipped tomorrow, so I should receive it by Friday. The price ended up being almost the same as Bike Parts Ducati.
new idle 2: https://www.youtube.com/shorts/4N9c3pMXeH8 new idle 3: https://www.youtube.com/shorts/RaLCmY8LIdg Hey everyone, I wanted to share an update. After replacing the MAP sensor, the issue has improved significantly. I also increased the idle rpm by about 50 units, and it’s running much more stably now. I also discovered something else—there was some carbon buildup near the exhaust valves of the vertical cylinder from before. I cleaned the area and sprayed some brake cleaner, and I noticed that the idle dropped instantly. This makes me think that the O-ring on the exhaust valve cover might be deformed. If this were on the intake side, I would say for sure that’s the cause, but I’m not entirely certain in this case. That’s why I’ll apply some liquid gasket externally and observe its effect during riding and idling. If my suspicion is correct, I’ll remove it and replace it with a new O-ring
Good news on the map sensor I’m not sure liquid gasket will survive the temperature of the exhaust manifold, best just to get a new gasket IMO.
Not the exhaust manifold, there's currently a leak in the exhaust valve cover. By the way, the crankshaft position sensor can also cause similar symptoms.
I made a new adjustment and reduced the symptoms even further. I slightly loosened the belt tension and placed a 5mm Allen key near the fixed bearing to fit it accordingly. I can say the engine is running better now. Once the weather improves, I'll do the following: 1- TDC 2- Lock the camshafts 3- Loosen the pulley bolts by a quarter turn 4- Loosen the belt again 5- Tighten the belt again 6- Torque the pulley bolts 7- Unlock the shaft, manually turn the engine, and make sure there's no rubbing or sticking. Once I'm sure, I'll fire it up. I read something like this: Apparently, we need to do the pulleys this way, just like before. Additionally, the 5mm Allen key method gives around 110-120 Hz from the fixed bearing side, and around 125-130 Hz from the tensioner bearing side. Also, there was no O-ring on the exhaust valve cover, which is strange. I hadn't noticed it while checking the valve clearance, but I'm sure I didn't drop it because the leak was there long before. Most likely, it was removed during the first Desmo service due to wear, and a new one wasn't installed. I solved it by lightly applying Liqui Moly's liquid gasket.
Hello everyone, I have completely solved the problem. I was seriously misled by following the service's marks. In the previous Desmo application, there was a 10-degree shift. When I did the change, I also shifted it by that much, so there was a total timing shift of 20 degrees at TDC. I bought a Ducati Timing Tool, and to lock the camshaft, I had a machinist make a camshaft locking tool by threading an M8 screw and reducing the tip to M5. First, I brought the locking points to the correct position using the timing tool. However, I realized that while I could easily lock the vertical cylinder into its slot, I couldn't lock the horizontal cylinder. I then removed the cover and manually positioned it to the correct spot. The camshaft locking slot was now exactly where it should be. I locked it in place using the tool I had made by the machinist and then loosened the pulleys. It is likely that the service personnel installed the belt by marking it without loosening the pulleys, which caused this slippage. And since all the covers were closed, they didn't notice it either. Then, I locked the crank using my crank locking tool. By the way, I decided to purchase Ducati's original belts. The Dayco belts seemed to have hardened a bit too much. I loosened the pulleys of the vertical and horizontal cylinders, installed my new belts, and then adjusted the tension. I aimed to keep it within a safe range of 130-135. (The 145 max limit is the minimum limit for a Monster 797 with the fan running at 80.) After that, I torqued the pulleys, turned the crank three times, and saw there was no rubbing or issues, as we can see in the video. So why didn't we experience any damage due to the timing shift? It's because the intake valves of the horizontal cylinder were in the closed position, and the intake valve was opening late and it was closing early. The problem was caused by this. Since the engine stayed within a safe position during the 270-degree rotation, I didn't notice any jamming or rubbing while turning it by hand, so I didn't see or understand it. In fact, I thought I had locked it, but I hadn't. That's why I learned that before every belt change, it's important to make sure the locking slots align correctly. Turns out, you have to think like, “even if everything seems right, something could still be wrong,” hehe. MONSTER IS BACK! Hehehe. When I removed and replaced the MAP sensor, why did it show improvement? Because when I removed the MAP sensors, the engine started running by ignoring the data from all the sensors. (Open Loop) Additionally, despite having the SC Project installed, the raw fuel smell has completely disappeared. https://hizliresim.com/lyl5d9c (Camlock) I made the ends flat with a lathe to create a screw thread. https://hizliresim.com/a7krkl2 (Timing Tool) https://hizliresim.com/buz72cf (Timing tool) https://www.youtube.com/shorts/KFAuzfJSOfk Thank you all very much for your help. If I need help with tools, I will keep you informed. The camshaft locking tools are very simple; any machinist can handle this job.
