The problem is likely with your charging system and is most likely (in order of easiest to check) weak battery, faulty voltage regulator, or unfortunately commonly problematic is the Stator. As always, your best bet is to bring it into your local Ducati dealer as they likely have experience with this and have a ready solution.

You would need to bleed the system to get the air out. I found the steps below helpful.


1. Remove the hydraulic line/banjo bolt from the slave cylinder.

2. Fill the slave cylinder with brake fluid through the hole where the banjo bolt threads in and reattach the hydraulic line/banjo bolt, and torque.

3. Remove the clutch slave cylinder from the bike and manually force the piston into the slave cylinder. At this point, I usually use a small C-clamp (~$4 from Home Depot) and a socket in the cylinder to hold the piston firmly into the cylinder.

4. Fill the clutch master cylinder reservoir with brake fluid and pump the MC until you see fluid going into the lines. You may have to squeeze the line to the reservoir and/or crack the banjo open a bit to get the intial air out of the MC (just catch the fluid in a rag or paper towel).

5. Now bleed the system as normal, but with the slave cylinder in the clamp.

The difference here is a) you've already gotten the air out of the slave cylinder, and b) you aren't pushing against the clutch springs while you're bleeding, so when the system is free of air, the lever will be rock hard. Once the lever feels solid, you can remount the slave cylinder to the bike. It'll take a couple of pumps of the lever for the slave piston to re-engage the clutch actuator rod, so just make sure that your reservoir doesn't get so low while you do that, that you reintroduce air into the system.

though cost will determine the final outcome... I was thinking of a repaint to a very high shine in gold or ???? Cheers Allbest would be a powdercoating job. pull bearings cush drive. send them off,,

When your 2016 Ducati X Diavel doesn't start, there are several steps you can take to try and diagnose and resolve the issue. Here are some troubleshooting steps you can follow: 1. Check the battery: Ensure that the battery is charged and in good condition. Check the battery connections to make sure they are secure and clean. If the battery is weak or faulty, consider charging or replacing it. 2. Ignition switch and kill switch: Verify that the ignition switch is turned on and the kill switch is in the "Run" or "On" position. Sometimes, these switches can accidentally get bumped or turned off, preventing the bike from starting. 3. Fuel level and fuel delivery: Confirm that there is enough fuel in the tank. Additionally, check for any clogged fuel filters or fuel lines that may be restricting fuel flow. If necessary, clean or replace these components. 4. Kickstand position: Some motorcycles have a safety feature that prevents the engine from starting if the kickstand is down. Ensure that the kickstand is fully retracted and try starting the bike again. 5. Spark plugs: Examine the spark plugs for any signs of fouling, wear, or damage. If needed, clean or replace the spark plugs according to the manufacturer's specifications. 6. Fuses: Inspect the fuses to see if any have blown. Replace any blown fuses with the appropriate type and rating. 7. Immobilizer system: If your Ducati X Diavel is equipped with an immobilizer system, ensure that the key you are using is programmed correctly and recognized by the system. Consult your owner's manual for specific instructions on the immobilizer system. If the issue persists after these steps, it is recommended to consult a professional Ducati technician or authorized Ducati service center. They will have the expertise and specialized diagnostic equipment to diagnose and resolve the problem with your 2016 Ducati X Diavel.

Go back to basics to figure this out. An engine needs 3 things to start and run. Air, Fuel and Spark. Remove any one of these and it won't start. Try this. What EXACTLY does it do when you press the start button -Nothing at all or a slow sluggish crank is most likely a flat or bad battery issue. Charge or replace the battery. Cranking at normal speed but not trying to start is possibly a spark supply issue. Test for spark at the plugs and work through the ignition from there. Cranking, coughing and trying but won't idle is commonly a fuel supply issue. Check you actually have fuel in the tank. Yes, I've made that mistake! I've also forgotten to open the fuel valve. Check you are getting fuel to the cylinders. A way to do this is by removing 1 plug wire and cranking the engine for 1 to 2 seconds. Remove the spark plug on that side and sniff it. A working set up and it'll smell of fuel. Refit the plug and the wire and repeat this for the other cylinder. From there work backwards through the fuel system checking the injector, fuel pump and the fuel pipe lines.

You may likely have to program a new key as it has a chip. The SBB key programmer on Ebay is great for cars but not sure about bikes but perhaps! Make sure your model is available in the indications given by the SBB programmer site on Ebay.
