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

Andy,

You could give these guys a try - BVM Moto. 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 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.

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......
