Just took delivery of a beautiful 999S (Parts Unlimited) on Sat from Miami dealer. Rode it 70 miles yesterday and very pleased with the bike overall (actually chuffed to the limits and smiling like a Cheshire cat the whole time!!!). First sportbike ownership, previously owned BMW K1200R, Duc S4RS and MV Brutale. So new experience.

Had a few issues/concerns and wanted to see any input from the experts out there...

1. Bike stalls at traffic lights (temp up at 215 deg!!) - engine cut off a few times when trying to pull off. Bike was running at time, gave a bit of gas and bike stalled. Easily started up again but a bit of a pain and also embarrassing with such a nice bike! This seemed to be a common issue with the 999/749 as I've read. Remedy? Is this an idle problem as suggested by dealer purchased from?

2. When pulling off from a stop, there's a funny noise and slight vibration, almost as if brakes were holding or suspension issue. Dealer purchased from said its probably a clutch problem and may need to be tweaked!

Bike was purchased with 3700 miles and dealer said it was not ridden for a year, basically sitting in the shop! Could this have anything to do with my experiences?

Just thought I'd ask and since I have the 2-year warranty I will definitely take to a dealer to get it checked out. Problem is our local dealer is new (jacksonville, fl) and not sure how good they are!

Appreciate any input - thanks.

Congrads on the new purchase! :D

The stalling issue is pretty normal on stock testastretta powered bikes. They tend to run lean and in hot conditions there isn't enough fuel getting past the throttle bodies. The solution is to put on an exhaust and have someone tune the map a bit for idle. A PC3 won't help because they don't work at idle, but some tuners have the ability to alter the stock ECU's fuel mapping.

The dealer might not be able to help, so don't get frustrated if they can't. You really need to seek out a specialist.

In terms of the clutch issue, dry clutches make noises... thats kinda how they are. ;)

Thanks for the info on the stalling issue tye1138. Hopefully I can sort it out soon. Will try to find a specialist locally. I've been told by many duc owners about a dealer in Ocala, FL who is supposed to be a guru on this stuff.

Regarding the vibration, I wasn't speaking about the dry clutch noise which I'm aware of with my S4RS. This is definitely something else. There's almost a shudder on take off, a brief one at that - again, as if the brakes are holding. Will take this to the dealer and see what they say

Thanks again.;)

Cogradualtions on your new Ducati 999S...commisorations on your stalling problem :(...hey it's manageable and will be fixed! In the mean time you can "bump" the fast idle lever...or choke lever on your lefthand switchgear. Fuel injected ECU motors do not have a choke perse, they have a fast idle. You can bump it a bit until you get it to a dealer to fix it properly.
If your impatient try a new, properly gapped set of plugs....sometimes that's all it takes.

PCIII's do work at idle.... it's the PCIII EX version that blocks out the lower range breakpoints for C.A.R.B compliance.

To fix the stalling issue, you need to double check the cam timing, balance the throttle bodies, richen the CO trim and reset TPS. It's stupid that you have to go through that, but Ducati had to ship them all out of whack to meet EPA requirements. And to add insult to injury, it will still stall on occasion around town. It's a minor annoyance to own a beautiful bike :cool:

999S equipment

Your 999S should have come with a "racing ECU" and a Termi half system, all the north american bikes came with them. Install them and your bike should run nicely. Mine does!

Mucho gracias for the feedback. I do love the bike and can accept the few quirks! My wife does (accept my many quirks), well that's what she tells me!

Will be patient and nurturing and anyway, these issues disappear in a flash when the gas ignites to push those RPMs. I feel very privileged.

Will let you know how it progresses.

I did all of these with my 2005 999S and it now rides down to 2500 RPM without complaint and never stalls. Plus, the Termi 1/2 system sounds so much better. Set your CO to 3%. Use the PC III to back-fill the 2, 5, 10, & 20% TP cells from 1000-4000 RPM smoothly.

The moaning on departure is a dry clutch phenomenon that can be partly resolved but not cured by installing an open clutch cover, and blowing it out with compressed air or a water spray from time to time.

The 2005 did............

From my understanding, the '07 Team USA's did not come with the Termi half system and ECU. I bought mine used & it had the standard exhaust. Maybe someone who bought theirs new can chime in on that...

I put the Termi half system on a few hundred miles later. It DOES run nicely & hasn't stalled.

Congrats, zimpat!

I had a new 2007 999s Parts Unlimited bike, and it came with a standard OEM exhaust and ECU.

Mine never stalled like that, but some do. Sometimes people stall them because they are geared so tall, that you have to slip the clutch a bit at launch and get the revs up.

My 999S was geared with a -1 front sprocket and that helped starting from a stop tremendously.

Ok, so the 2006 999S came standard with the racing ECU, air cleaners & the Termi half system, I would have expected any of the 2006 "S" models to come with it, as mine, once installed made my bike run perfect, no need for a PCIII with those parts, in the "race" kit, supplied by Ducati as a no charge "kit".......

Set the trimer and adjust the TPS. its one hour job. That fixed the stalling problem on my 999. install the termignonies first before these adjustments.

Oh also as mbevans said, the racing kit might solve the problem, if not, do the trimer and tos adjustments. DO NOT USE THE PCIII !!!!!

I also bought one new and can confirm they only came with the stock exhaust.

I picked up a 999R Fila racing exhaust 1/2 system that came with those bikes and had it installed. No stalling issues for me.

I will say my '04 ST3 has a tendency to stall when it's cold. As others have mentioned adjusting the fast idle until it's warm seems to solve the issue. Once warm - no problems.

Cheers and great purchase. I'm biased, but think those are some of the best looking and fairly rare bikes on the road.

Stalling 999

I have a 2004 999S with full Termi system. My bike stalls occasionally and has nothing to do with how I dump the clutch to leave a stop. The bike has even stalled rolling UP TO A STOP with the clutch in. A guy I know at a dealership said there is a "washer" on a "sensor" that comes in varying thicknesses. He said I should buy a couple different washers and experiment with those. I have not done this yet as sometimes the bike rides without flaw, but just a few days ago the bike stalled three times. As mentioned, it makes you look like a noob. One of my stalls was just as a Yamaha R1 (who anticipated the light) passed me while I was stopped. Super embarrassed even though I maintain the stall was not my fault.

I find myself blipping the throttle more - seems to help.

I love my 999 I just put a full system 53mm on mine. I have to say I've never really had a stalling issue. And I have almost 12,000 miles on mine. I do have an extra half term system on my shelf if you are interested in letting breath a little better. Email me if you want pictures. I've been planning on placing it on eBay or the for sale section just haven't gotten around to it. You can email me at [email protected] if you interested.

I have the 07 Team USA 999S, the termi was not stock but i have it. The ECU is different but not the race/termi ECU. Two things i did to rid the stall and sluggish take off were to install the Dobeck FI module. It does allow idle input. Couldn't be happier. Next, unless you are going to track the bike go with the supersprox 15/42 chain set. Its is your call on the 520 or stk 525. I went with the 525. I also changed the throttle ramp by installing different throttle. Not as quick. Again I do not track the bike. Top speed is reduced with the 15/42 but zero to 155 is quick as hell and winds to red line fast in each gear. You could have other issues as stated by others that will solve the problem. This just worked well for me. Yea I hear ya. Nice gear, beautiful bike and you stall. Aside from wondering if the person behind you is going to shorten your wheel base not a good feeling. Been there.
