Hi all. I have noticed that sometimes the throttle response on my bike seems snatchier than normal, this is in touring mode. I have also noticed that sometimes when starting it up, it seems to idle at much higher revs than normal, and it seems that when this happens the throttle response is more snatchy. It happened today, not at all cold, started it up and it idled at about 2000rpm, before dropping back, and then the throttle response was just too snatchy - it was like the throttle response in sport mode.
Sounds like a sensor might be gummed up or on it's way out. Maybe O2/Lambda sensor in the exhaust. They're renowned for causing erratic fuel mixture when they play up.
Thanks for that. Will have to get it looked at, though will be disappointed with Ducati again if its going after only 1300 miles. Yet another trip to the dealer, they must be kept very busy.
Mine also exhibits these symptoms sometimes, it got worse after the first service. Very snatchy throttle in sport mode.
Mine does the high idle on start up and only since the first service 200 miles ago. Haven't had the throttle problem as I've got the engine on high in touring. I wonder if there was an update that has caused this ?
Or using poor fuel, that causes stickiness, never had any of these symptoms on my 3 Ducs I have owned / own (2 MS's and 821 Monster, total milage so far 20k in a few years) but I always use Super Unleaded Fuel.
Well, no. Character would be something that is common to all examples of a specific model. My own DVT shows no symptom common to the OP's bike.
That's an interesting point actually. Out of habit I had been using super-unleaded in my DVT as I have been on most of my bikes over the years. When looking at the owners manual there are a couple of aspects which are worthy of note - specifically that specifies 95-98 RON fuel, which would indicate that regular unleaded is absolutely fine. Also, the manual states that no fuel greater than E10 which relates to 10% methanol, which is widely available on the continent in at-the-pump bio fuels. E10 is broadly similar to 95 RON fuel, but the consequences of using a fuel with more than 10% methanol can damage the fuel system, as it can corrode certain materials. That would indicate that in Europe that the bike should only run on a UK equivalent 95 RON fuel. At the other end of the scale, 98 RON would exclude the use of other fuels available at the UK pumps, such as Shell V-Power Nitro+ and Tesco Momentum, as these are both 99 RON (in my car I can only use these fuels, which is how I'm aware of this). I've actually started running my DVT on 95 RON and it feels noticeably different. The bottom end is a lot smoother and I there is also noticeable a benefit in fuel economy, the latter I would have not anticipated. I can't notice a significant difference in the mid-range or top-end. To me, the bike just runs nicer with regular 95 RON. That said, I wouldn't fill up from just about anywhere and I avoid supermarket fuels and anything I've never heard of before.
I run everything on any thing above normal 95, and for the most part it is actually run Shell V Power, have been doing it for yrs. Even my Lawn mover is run on V power, it starts first time every time after 6 months at least lay off
I couldn't help but think that since Ducati have made a lot of noise about enhanced knock sensors on the DVT that they're almost expecting people to run on cheap-o fuel and have set the whole engine up around this. They have to support a range of fuels and taking everything in the owners manual into consideration it seems that 95 RON would be about the sweet spot as effectively that's what European riders are going to be using the equivalent of. 97 RON certainly doesn't make it run any better. The reason I came to these conclusions is that I'm going to Germany at the end of this month and remember that from last year I had some questions around E10 and higher in my Yamaha Tracer (which was noticeably quicker on 97 RON and above). I'll certainly have to be mindful to not put in anything higher than E10 as the manual states that you can damage the engine.
My car is particularly picky. I have a Nissan GT-R with a stage 3 tune which is putting out around 610bhp. It requires a 99 RON fuel to run at full boost otherwise I need to switch the map down to a 97 RON fuel and then wait until I've put two tanks of 99 RON through it before I can switch back up to the 99 RON map. It will run just fine and you'd probably not feel the difference ... until the engine dies.
