View Full Version : 999 throttle movement

Going on from the thread 999s stalling, in relation to the vague throttle feel, i am looking for a comparison between the 999 twin cable rotation and feel and the 998 single cable.

I have to say i dont recollect my 998 needing two grips of the throttle in the riding position to achieve full throttle.

With a protractor i think there is over 90 degrees of rotation on the 999 std throttle. D/P do a Corse quickaction upgrade, so what does that tell us. Im also told this is very expensive.

Ill try to get a comparison from one of the 998 boys.

The genuine products are available from a 998 testastretta to convert the 999 to a single cable........which hopefully is less rotation.

Andy,

All the single cable type throttles (748,916.996,998) have 63-65 deg rotation, 999 is 94-95 deg rotation. Both the above figures give 36mm of cable pull, the max for wide open throttle on a Duc.

Incidently, if you're looking at fitting a single cable type to your 999, Ducati original throttles are made by Domino. Widely available and a lot less expensive than buying the same part from a Duc dealer.

Hope that helps,

Neil.

I did a quick search and found this

http://www.redracingparts.com/en/english.htm

Then look for quick gas controls

Now which one is the right one :puzzled:

Andy,

You could give these guys a try - BVM Moto (http://www.bvm-moto.co.uk/throttles.htm). I don't know if they actually have the one as used by Ducati in stock but you can get the specs and part numbers off the Red Racing Parts (http://www.redracingparts.com/en/product/gascontrol.htm) website so being a Domino dealer they should be able to get one in for you. Might work out a bit cheaper than buying from Italy. Having said that, apparently Red Racing Parts are very good with excellent delivery service.

Cheers, Neil

Just got my bike back from the dealers (999S) after its first service and having also had the throttle body changed for a 998 single cable type. Have to say in ythe short time I have had it back to assess the improvement it feels a million times better than the stock item with a good deal less rotation and much more responsive just as I remember my 998 being. It wasnt really that expensive either and it makes the whole experience of riding the bike especially at low revs much much nicer. If anyone wants more info then contact Pro Twins who have successfully done this mod to several other customers bikes including their track 999S which has been whooping the a@@ off several others of late at the UK circuits.

Rod, could you get the part numbers required for the mod?

andyb
30-Jun-2004, 22:01
oh and any piccies of your bike mods, both the position of the cable exit re the m/cylinder, and the bracket used on the t/body end?

Red Racing told me yesterday that they do not sell a direct replacement quick action throttle for the 999

Been to jhp today, and ran it by the guru. Seems that its not impossible, (as rod has shown) however concerns were raised re the poss of the throttle being forced to stay open with the volume of air, hence thats why theres a return cable.
However, this could poss be eliviated with return springs from a 998R, as that still has a single cable throttle.

On their race bike, they have a gucci billeted Corse item. John is saying that the sum parts for this have to be ordered seperately = around £200-£250 + labour!! Although this is quick action and retains twin cable.

Therefore there has to be an attraction of achieving quick action throttle using single cable (998r) on the 999.

Still found out that the monster throttle is same as 998 except the cable exits low below the m/cylinder, ideal for 999 set up.

The quest continues.... It would be nice to know what others like pro twins have done/used to achieve this......

I've just fitted a quick action throttle I bought from:

www.extremebykesportz.co.uk

It works very well - feeling much more direct and reducing the required rotation from over 90 degrees to around 65 degrees (sorry to be vague, but I've nothing to measure this with).

The new throttle comes with two cables, but I managed to fit it retaining the original Ducati items - saving the chore of splitting the airbox. This required making two small collars to locate and hold the original cable ends in the new housing. I may fit the new cables at a later date.

The new throttle also comes with a choice of three cams; approximately 47mm, 53mm & 61mm in diameter. I guessed and fitted the 53mm cam to reduce rotation down to 65 degrees. For reference I measured the stock Ducati cam at 45mm.

As the new throttle is a non-Ducati item it did require a few minor modifications to get it to fit properly; eg filing about 0.5mm off the mating faces of the housing so it clamped securely on the Ducati handle bar. All in all, it took about 3 hours to fit and sort.

The throttle cost £150 inc VAT plus £8 delivery.

Examining the now redundant Ducati throttle showed my earlier attempts to reduce the play in the cables had merely resulted in stretching the locating holes in the original (soft plastic) cam.

Meanwhile, if you want to see the quick action throttle itself, go to the extremebykes website and look under accessories.

wait a while though, i know pro twins do the single cable jobbie, dont know how much though.

Ive got jhp on the case, dont know how much though.

The corse item is going to be £200 ish.

The one reapers done is £158 + fitting it for the non mechanicals.

I think there is quite a bit of money to play with there re the jhp option.


But, by all means lets start a list to offer up for discount to whoever.

Andy mate. Keep us posted on this one..........let us know what you end up doing.

You must be keeping that R pinned if you're finding the throttle rotation a problem.

Must come from wringing the life out of the firm's Pan-Europeans ;):lol:

Hi Everton, its a tough job but someones got to do it....:saint:

You up for a throttle mod then?

Nathanus piccie is interesting, although i think if you used a monster throttle, or rotated the 916 jobbie, the cables would route better underneath the m/cylinder?

Well I must admit I never really noticed any issues with the throttle rotation until you brought the topic up.

There is noticeably more travel than on my VFR for instance. I can't say I remember much from my 996.

I'll be checking everyone's bike tomorrow now........... :lol:

I've just got a 999S and I definitely need a quicker action throttle. Can anyone recommend a dealer/workshop near West London who could supply & fit the Corse kit?

Does this mean that there could be some kind of group purchase - maybe with a discount ?

imo, i quite like to the extra throttle travel, you can be more precise with how many berries you are giving it through the twisty stuff!:smug:

09-Jul-2004, 10:41
me too, i've been looking at this post but dont really feel the need for any quicker throttle action myself. if you've got 130+ at the rear wheel i would have though the key is getting the power on smoothly rather than more agressively. maybe people ride alot quicker/harder than me.

i know for a fact that i found it really hard to put the power down in the wet when i was out in spain and for me at least any quicker action would have been quite simply a nightmare.

Its so you can crack that sun bitch throttle open for the power wheelies ,with out having to have a double jointed wrist :devil:

Any progress with this, seems to have gone a bit quite :puzzled:

Same for me...... just feels like a crap fit !! You could take some slack out of the cables.... worked for me :cool:

Sorry guys, been in Spain........

Well, first of all tell the 996 998r boys their throttle actions too quick and unmanageable, with the 120+ horses!!!! I think not.

The whole purpose as far as im concerned is to take away a vague throttle feeling that needs 30%(+ all the extra slack) more turn to open it.

I suppose riding only on smooth tracks means you can get away with this Dickie...



:P

Hope to find out a bit more this week.

got mine sorted today, a bit of a fiddle but not rocket science...
just remove the return pull cable ,
cut off the plastic curved portion on the end of the pull cable,
fit a screw adjuster (like on a push bike or moto x bike),
fit on the 996 throttle assy and re adjust the cable slack
job done..

Nice work mate. I dont want to *******ise the original cables though, so im using a 998 cable. Slightly larger externals but same job.
This way ill keep the 999 stuff for that day when i swap it all back.

have you fitted the 998 cable yet?
i was under the impression that it was also to short.....

f I understand correctly JHP are looking to have custom made dual cable throttle. No firm news on price or when it will be available, but I was told to call back in a couple of weeks for more news

too sensative for you and the whole 996/ 998 range, i think not.......
Dont forget what youve "upgraded" to, is std on the other shape!!

06-Aug-2004, 21:16
oh and if u used the std 996/8 throttle cable , itll be too short.!! perhaps thats harf yer problem???

09-Aug-2004, 12:08
not too short if you route it in front of headstock instead ofbehind

Had mine done last weekend at Pro V’s, it’s so good to be able to get full throttle in one twist instead of having to take two handfuls, the spring tension is quite a bit more than the standard throttle but at least I’ve lost that vague feeling, all in all very nice indeed. Also had the suspension setup and new Carbone Lorraine front pads fitted, what a difference, it feels like a new bike. Can’t wait for the rock this week.:devil:

Oh nearly forgot, had a slipper clutch fitted as well. Don’t you just love these money pits called Ducati’s:(

Throttle mod £200.00 Supplied and fitted

Well, I got it back on Thurday in time to ride up to TA3. I'd say it was definitely worth doing. Right up there with the Termi exhaust & vented clutch cover ;) The whole throttle application is much more precise not to mention actually getting full throttle on a single handfull... not that I got to use full throttle on a damp Rockingham though :rolleye:
