Has anyone put a fatduc on a 2013 multi and can advise of the difference it makes to low down fuelling. Also is there anywhere in the uk that sells them
The question is why fit them on a 2013 bike? I have a 2013 bike and the dual spark heads make a big difference, the engine is smooth at low revs, you can pull away in 2nd if you want and it just pulls cleanly all the way to an illegal speed! In 1st it will do low speed manoeuvres easily on full lock at tick over (you guess why I know ). If your 2013 model doesn't do the above then something is wrong and the dealer should fix it.
hi I've only just got the bike so I'm still getting used to it, but do find there is some surging low down 1.5k to 2.5k when filltering where it sort of hesitates before accelerating. Not horrendous but think it could be better. From what I've read it's normal with emissions I can't guess?
Mine does this a bit in the standard Urban setting, so I have changed the Urban engine setting to the low150bhp touring engine output. No problem with the hesitancy with this approach.
Hi yes it is mainly but a little In touring as well. I don't know you could change the powe settings for a mode as ell I thought its was just the abs and dtc.
I had a 2010 model and that was definitely "lumpy" at low revs, the new 2013 bike (which has just had a 7.5K service) shows no signs of low rev surging in sport, touring or urban modes - it is, in comparison, a smooth engine. All big twins will have some vibes at very low revs and I would admit that I spend as little time as possible in the 1.5 - 2.5k rev range. It's either demonstrating low speed manoeuvres on tick over or else I am powering up from tick over to 3K+ revs. It is something that you will get used to I am sure and I doubt Fat Duc's will help that much on the twin spark head bikes.
Thanks mate. I'm not rushing in to anything just after afpdvoce really as keep reading about how fat duc has transformed the bike.mim tempted as I dare so I would lose anything to buy and try then re sell if not bothered for them. Won't be doing anything till first service anyway.
Have you actually found a problem with the fuelling or are you looking at buying the parts in case it happens? To me it's like fitting a steering damper in case the bike gets a bit flappy because you've heard it can happen but until it does it why worry?
I would agree with the OP. I've just dropped my 2013 off for its first service and find the fuelling to be out slightly. Not enough to cause a major issue but there is no chance in hell I could pull away in second gear with mine with riding the clutch majorly. I had the dealer fit a Leo Vince can and cat replacement with the valve removed. So mine is technically not standard 2013 although no other mods have been done engine /fuelling wise Low down revs is crap in all modes. I'm considering both options at the moment of a remap of standard ecu or a power commander to try sort out the low revs. Although this is my first big twin bike so it may just be the need to get used to it first and possible same for the OP.
Mine's now got 5.5k miles on it and the only time it's been a bit of a pig at slow speeds was when the air temperature was up above 35c when it felt a bit hesitant to pick the revs up. I don't use it for commuting and the only filtering I do is either going to the Channel Ports or back from them when I'm off on holiday so the bike gets an easy life and I don't have to suffer the bad points.
i would def get a power commander. I've had them on virtually all my bikes and it has transformed them but there is no pc for the 2013 at present I believe
I'm the same. Always had power commanders done on all my bikes including my race quad years ago. I have a pc5 On my Z1000 and it defo makes a difference. But reading up on the mapping the standard ecu there seems to be a lot more options and ability to map. My main issue is Iain Glasgow and CJS are in Bristol :-( not exactly round the corner for me. But going to speak to my. Dealer this eek and see what they think.
Ok the 2013 Multistrafa can be remapped in the same way and standards as the previous models. Someone was kind enough to bring me one and after approx twenty hours of prep marking out the maps in the binary code I had something to work with.then it was a case if having the bike on the dyno to check and confrim findings. Luckily because we develop our own system for tuning bikes we do not rely on waiting on third party's programs to get the job done. There is a flaw with the 2013. You cannot just disable the o2 sensor. Doing this makes them run worse unless the fuel map is recalibrated at the same time
Had my bike now for 3 months and the low speed fuelling is still as bad as ever in all modes, it's a pig to ridesmoothly in low speed stop/start traffic. I have just noticed that one of the cables on the exhaust butterfly is quite slack, could this be the problem ??? My dealer has obviously missed this but I would have expected boththe butterfly cables to have little or no slack ??? It seems strange that some 2013 owners say their bikes are fine awhile others have this rough bottom end.
Leave me alone....I brought the steering damper 'cause it went all flappy....otherwise I know what you mean. :biggrin: I can't beleive Ducati would be so stupid to release two versions of the bike with a super lean issue down low. It might be the exhaust valve...get rid. Then decat, then performance exhaust, then a remap. Then more carbon, then more CNC parts etc etc until you bike represents the GDP of a small island.
That person was me :smile: . Huge thanks to Chris for all the time and effort he put into this. Anyone considering getting it done then I recommend getting in contact with CJS. Chris is relentless in getting the best out of your bike and somewhat of a perfectionist. Gains were around 10bhp , but more importantly the drive and fueling with a full Leo Vince and performance air filter was nothing short of phenomenal. I found fatducs did nothing to my 2013 and the LV made the bike run incredibly lean under 3k rpm (no surging, just a lot of popping). Infact, if I recall the 1st dyno run for base readings found the rear cylinder was so lean it was off the measurable scale. A wet ride home on Saturday evening, but boy did I have fun on Sunday. Thanks again Chris, top man with an obvious passion and skill for what you do, I certainly left humbled. Steve.
