So I took the bike (2015 Red Icon) out for it's first run of the year after going through the pantomime of charging the battery and finding the connector provided is not compatible with my battery optimiser. Anyhow. got over that and... After running well initially begun to run unevenly with pronounced stuttering at low/mid engine speeds. I stopped at a services and called the dealer and it is booked in, also for the sidestand recall. On pulling away from there, normally a very smooth affair it cut out and I nearly dropped it. On return home, I checked the plugs and they looked ok. The battery is firmly connected. I can't see anything obvious, so I'm puzzled. Is this anything to do with the sidestand recall? Or is it something like dirt in the fuel?
Bike is pretty standard apart from Throttle tamer, lowered suspension and a few cosmetic bits 'n bobs. It has 3k miles on the clock and is still under warranty (just.) What do people think? I don't want to get taken for a ride by the dealer.

Sounds like you have had he bike parked up and unused for a good while?

Has the fuel gone off? Or did you fuel up at the services when you stopped there and it still continued to have the same issues?

Edited to add.
You don't fill up with crappy supermarket fuel do you?

If you stored it with gas, I would siphon it out & put fresh gas in it's place. Sounds like dirty fuel. It is under warranty, so you will not "get taken"...relax.

Maybe try pouring in bottle of carb/fuel injector cleaner with your next fill. From past experience with outboard motors, gasoline will foul fuel systems sooner than one might expect.

How long has it been standing still? Could be just a gunked up injector...
Exactly this.


How long was it sitting? Was it in frozen temperatures? Was the tank full? Did you put anything in the tank during storage? When did you change the oil last?

I'm spoiled with access to a heated garage. I put a dab of Stabil in the tank before winter and fire it up once every week or so. If you don't have that luxury, there is a pretty extensive winter storage check list to run through.

You might not choose to drain the tank or change the oil before your first ride, but you are probably experiencing one of the reasons why people do.

Best to drain the tank IMO. You might get away with adding some injector cleaner to the tank though.

To me it sounds more like the engine temperature sensor has failed or has a poor connection, creating an overly rich mixture. The temperature sensor is fitted into the front of the vertical cylinder.

Having a similar problem.. been out for a few rides recently as the sun's been shining and all good(2-300 miles in the last week or so(with a mix of crappy supermarket fuel and shell/bp)). Decided to go to class tonight on bike... parked up, left outside the college for 2 hours(10-12Degs C).. came out, fired up.. started, but, engine light on, popping, running like a dog.. rode home very gently, stopped at red light and a bit of smoke(smelled like burning oil).. got home and in the dark when I'd stopped and switched off the engine it was like there was a red light coming from underneath the bike(not a big mechanic but it was at the back of the engine towards the rear wheel on the chain side)...

This happened about a month ago too..(same situ, left outside for a couple of hours in the cold etc..) - took to Ducati Aylesbury... needless to say it was running fine again when I rode up there.. they connected it to whatever they connect it to, said there had been 1 registered engine fault, but it had cleared itself and nobody knew what it could be.. they were sending the reports to Ducati Italy for them to look at but nothing back yet..

I'll be onto them again in the morning, but I'd lay money on it running fine in the morning..

Any ideas?

The red glow was most likely the cat? (You still have that?)

If I had to guess it may have been dirt in the injector, or the injector as such failing intermittently as a result of an electric gremlin...

Thanks Max, the glow died down after 3 or 4 minutes.. I do love an intermittent electric gremlin... grrrr.. back to the shop...

Hello

Imho, you faced an issue with the temperature sensor giving bad informations to the fuel injection system.
I also noticed, sometimes, when riding the bike in a cold temperature, just after exiting a warm garage, that the engine behaviour is abnormal until the T° displayed goes down enough to be similar to the ambient T°.

It may work in both ways : a T° sensor giving a too low value in a warm ambient T° or reverse.

What fuel injector cleaner are you using to add to the gas tank? My Scrambler just spits sometimes so I don't think it would be a bad idea to toss a bottle in?

Though now when I think about it, it only happens during decelerating when I'm blipping the throttle...this I believe is normal but maybe someone can confirm?

I use Shell 0% Ethanol fuel but I'm almost positive that previous owner used lower grade fuel for the 2 years he owned the bike.

I would say normal but I don't think it would harm it, ive used redex in my old track car and I could defo tell the difference but it had done 60,000 miles.

The first 5500km on the bike probably saw lower grade fuel. So maybe one bottle of SeaFoam would be ok...I just don't want to cause any harm to the engine...

If you mean the popping from the exhaust on overrun (when you shut the throttle and there is load on the engine as you decelerate) that is normal. I was pleased to hear our Scrambler do it. The (insert expletive) engineers at Triumph mapped it out of the Tiger between mark 1 and mark 2 so I no longer have the pleasure of those nice pops and crackles.

My pop happens when I drop down a gear, blip throttle and instead of the engine revving up the exhaust spits/pops and I have to blip throttle again. It reminds me of when I see race cars on TV or pimped out honda civics on the road. :p
