Hi, Did a 200km ride some time ago on my 1098 and noticed some stutter. Now I realize this must have been some misfires. Ride the bike today and it lost power, I realize it was running one 1 cylinder. I did check the Ohm resistance between the negative of the battery and the frame, seems all fine. Is there anything you can advise I can check?
Hi, I just had a similar issue. My horizontal coil was part of a misfire issue, just barely in spec (reading 600ish where spec on my 848 is 650 mΩ±50). Replacing that coil helped out a lot (and resetting the TPS). My issue was more about chasing gremlins for a 13 year old bike with 1,100 miles on it. Entire fuel system was trashed.
Yes. Best hope it is a coil pack, else eliminate the cheaper components IE. HT lead and spark plug. If not then it might be the ECU. More expensive but not difficult to replace.
did that journey involve riding through heavy rain*? so many things, but as said, front cylinder coil pack comes to mind if so*
there is a particular engine ECU Ducati used that was prone to failure causing a misfire. i've got a sneaky feeling that it isnt, but, i've no idea if it's used on your bike. my gut instinct is going to be a sparkplug/ignition coil or injector. swapping the coils being the quickest and easiest first step.
First thing I’d start with is a new ignition relay. That’ll make sure the pump, coils and injectors have a good supply. Check also to earth lead to the ecu. Coils are relatively common. If it’ll run, see which cylinder is down… it’ll have a cold or cooler exhaust header. Other than having removed the LHS fairing panel, you’ve got your bad cylinder, then you can look at coils or plugs.
That are some very helpful replies, thanks a lot. I wil start to tick the boxes one by one. Since it's winter I'll take my time, will update when I've been working on it and found something. I think I start with the spark plugs btw, seems relative easy to reach and it might have something to do with me cleaning the tank and starting the engine a few times and switch it off again. I did not realize then, but I read this can get the spark plugs messy quite fast. Been a while, but it is as simply as getting one plug out, disconnect the other one, ground it to the frame and press start? If it wont start, check another plug, if that also does not start, switch coils? Depending on the results I can check spark plug and coil test.
Do you know which cylinder it is yet? If you have access it should be very easy to determine that. Assuming the bike starts and runs on one cylinder then get it running and disconnect either plug lead. If it stops then the other cylinder is faulty. If it keeps running then you have the faulty one in your hand. Then you can simply swap parts one at a time; plug, lead, coil pack. Hopefully the fault will move then you can just replace whichever component is the culprit. If it does not move, as was the case with mine, then it might be the ECU not sending a firing trigger to one cylinder. Be interested to see what you discover. Good luck
No did not work on it, not sure which one. Thanks, simple but smart way to check, will do. Hope it's the one below the tank, the one behind the radiator seems a bit more difficult to reach.
