It's very simple - full throttle with only 75% of the twist, compared to stock. It feels even less.

I was distracted by the long travel, had to change my grip before hitting it or end up with my wrist too low on full throttle. I'm on a 800, so full throttle is more relevant for me than if you're on a S4R. Now, it's much more effective - racier if you like 8) 

I think I found a mod to compete with the 14t sprocket for effective and cheap - $47 and so worth it [thumbsup]

My brain's not following how this thing works.. I'm all confused. Does it hit the throttle stop faster? the website says its a linear rate - 25% throttle = 25% at the cam.

Its thats the case, why would the throttle not twist the same amount?

Dont get me wrong, its a great idea. It just seems like you're changing lowering the amount the butterfly valves open.. Hence your new 100% throttle is actually 75% of what was capable before..

I got to be thinking of this backwards or something..

It will fully open the butterfly valves with only 75% of the twist of the grip.

The difference is the diameter of the cam. I see it as different gearing. If you imagine a very small cam, it would rotate to full throttle with very little movement/pulling from the wire.

The "linear rate/action" has to do with the shape of the cam - not important, because I think stock cams are linear as well.

Nice find!!  [thumbsup] Called em to see if it'll fit my RS (no answer, left vm). On the site they say no for 998, 999, 749 but not sure if that is just the throttle body setup on those bikes or for all 998 motors. Def gonna get one if I can...

I would like one if it will fit the DS engine of the S2R1000. Looks like a non fit, anyone know if the DS has the same trottle cam as the 998+999?

Yoyodyne makes a 1/4 turn throttle which is essentially the same thing.

Evoluzione also makes something similar, which I have on my 848...it's nice.  8)

Comes in any color you like, as long as it's red.  [bang]

Not true. I emailed the guy who makes them and he picked one out for me before he sent a batch to the anodizer. So it also comes in "Natural" if you're willing to wait  ;D

And a big  [thumbsup] on this mod. It took less than a day of riding to get used to the quicker throttle response, but man it makes getting on the gas easier.

Downside: Slightly more pressure on your wrist on long rides (shorter turn means more strength needed to turn the throttle)

Yeah - it's quite a lot easier to get it going with this installed. Along with my clip on mod I rerouted the throttle wire, almost no resistance AND the quick cam - I feel like I have a lightened fly wheel.

I experienced the opposite from you with the wrist issue, but that might be because of the rerouting result I got.


The Yoyodyne seems to come with several gearing options as well - double vroom [thumbsup]

Evoluzione is more advanced - they supply slower action at first and then faster action when you get closer to full throttle - smart [thumbsup]


Hey Colin,

why wouldn't it fit the S2R1000 - doesn't your cam look the same as mine?

I'm about to order the 14T sprocket.  Maybe I'll slap the cam and sprocket on at the same time.   [evil]

im lost... it says 75% turn of the wrist = 75% throttle opening yet it says that at 75% wrist turn, you get 100% throttle opening.

the first 75% = 75% they are talking about the rate of throttle opening. As in the evolutions one mentioned, the rate of throttle opening (% of throttle open for % of wrist turn) is not the same accross the range
example of a variable throttle: from idle, you twist your wrist 10% and the throttle opens 5%, but if you are already twisting to 90%, the last 10% you twist, the throttles open 15% (just a fictional example)
on stock, the rate is the same whether you are just getting on it all the way to wide open throttle,. ie 10% of wrist action always = 10% of the throttle opening hope that makes sense

When you loosen the nut to remove the throttle cam, should you brace the cam?  It seems that the nut is on there pretty tight, and just turning it with a wrench will put too much pressure on the butterflies.

They are describing two different things. 

The first:
The throttle input is linear.  A 1/4 turn of the wrist means the throttle valve has been opened 1/4 of it's span.  A 3/4 turn of the wrist means the throttle valve has been opened 3/4 of it's span.

The second:
They are comparing the scale of their aftermarket cam to the stock one.  A full turn of the wrist with the new throttle cam provides you with 100% throttle opening, however, the position of your hand is only 3/4 of what it would be with the stock cam. 

I have something like this
http://www.splatshop.co.uk/controls/domino-fast-action-throttle.html (http://www.splatshop.co.uk/controls/domino-fast-action-throttle.html)
Mine is by brembo
Think it works the same (on the other end)

it looks like the cam is smaller radius.  Motorcycle Consumer News had this product on their back page in Feb http://g2ergo.com/shop/catalog/G2-Tamer-Throttle-Tube-for-Ducati-267.html (http://g2ergo.com/shop/catalog/G2-Tamer-Throttle-Tube-for-Ducati-267.html)

the shape of the cam is ramped so the low throttle positions are less... snatchy? i guess.. less on/off.. abrupt..  so they say, and so the article in MCN said (on a ST1300).

I was considering it, but not sure how much benefit I'd see on a 620.

from the magazine

what do you(collective you) think?

I think i worry that this might cause me problems if I also put in a light flywheel... Maybe not, but it seems like there'd be less manners at low speeds if both were on ze bike.

I was considering one, but I too regularly inadvertently launch the front wheel from a start.  I see the fast throttle cam as a mechanism for doing that faster/more often.  Probably not a good idea.

This afternoon I removed the OEM throttle cam, drilled a few holes in it and polished it up.  It looks pretty cool.

Ahem. Pictures.

<--- Lightened clutch & flywheel + 944 hi comp kit + lowered gearing

No problems.

Like I said, it takes a day to get used to it, but after that you're fine. And I live in a metro area, so my learning curve both was, and had to be, pretty quick  ;D

wait, did you do the fast throttle cam too?
I'm about to lighten the ol' clutch and flywheel up, so my concern is lots of change at once throwin' my technique to heck.

my understanding is the G2 ergonomics throttle is designed to resolve that throttle problem.

You and I, with smaller engines, can benefit from quicker action - not much danger of overdoing it for us. We do not need the initial slower action of the G2 or Evoluzione systems.

I understand the worries for S4R riders, but I think it's easy to get used to a quicker action.

My own reason to get it was that I don't have to move my arm/wrist as much = better control. It was, A: start with a high elbow or B: end up with a too low wrist angle.

how hard was the install?  do you need to re-set anything?  I too have the 800
Thanks.

I have an s4r and was thinking of getting one of these as the stock cam takes soooooo far to get to WOT.  I will rely on my fat ass to keep the front down as always.

Ask Pompetta to walk you through the steps [thumbsup] Mine was put on by my curious dealer for free, since they already worked on the bike.
I think it's as easy as it looks - nut off - remove OEM cam - put on Electraeon cam with the throttle wire in place - put nut back on - adjust wire.

Im about to switch to the speedymoto tall boys and im picking this up too. how did you route the throttle wire?

The throttle assembly was rotated. Throttle wire exit now sits on top of the bar, it used to be underneath. Check out which way you want it BEFORE you drill the nob hole in the bar. My wire goes through the SpeedyMoto top triple - if you have the stock triple you need to decide if you go in front or behind the triple.

More importantly, for me anyway, was to reroute from behind/inside the large wire bundle that goes along side/under the tank. The throttle wire made a detour there, which proved to obstruct it's movement quite a lot. The second picture shows the beginning of where the wire now routes on the outside of the bundle.

Ask again if I'm being unclear ;)

(http://i329.photobucket.com/albums/l394/stopintime/bomb019.jpg)

so your throttle assembly is basically upside down now? and where its routed under the tank is now separated from the wiring harness to give it a more direct rout? 

Yes and yes  [thumbsup]

I'm not sure if you must/need to do the throttle assembly "upside down" with the Tall Boys.

How does this mod affect the choke/fast idler.  On my bike, it idles at 1.2k rpm.  With the engine fully warmed up, if i put the fast idle all the way up (as in a poor mans cruse control) my bike rpms are at 3K.  How does this affect your fast idle.

Separate systems - they don't affect each other.

You sure?  I unfortunately can not verify myself as my bike is back in the states and im in Korea.  If i remember correctly, although the fast idle is through a separate cable, if you jack the fast idle all the way up, it remember seeing the main throttle cam moving ever so slightly. 
The fast idle system is separate, but i thought it was separate in the sense a separate system directly influence the throttle cam(separate from the obvious throttle).

I was hoping that it does influence the throttle cam because it means that my 3k rmp with the fast throttle jacked up would be higher.  Maybe not up to 4k but higher than 3k.

Ill be getting the 14T and the fast throttle cam fo sho!!!! Anyone else done both? Oh yeah, will this work on a 696?

on another note: fast idel = poor mans cruise control = really????? hmmmmm

Yes, poor mans cruise control.  I think it works better than a throttle lock as it really is basically the same method of attaining "cruse".  A throttle lock only pegs the RPMs, it does not actively maintain a specific speed.  The fast idle can run the RPMs as high (at least my bike) 3k rpm.  That really is not high enough to maintain much speed higher than around 40 mph. If you can get the rpm to 4k, than you have more range in speed to work with. 

There are ways to rig the fast idle to essentially function as a method to hold rpms at a specific level, thus cruse control.

As usual, I can't take a picture to save my life, but here it is.  In "real life,"  it looks much better.  ;)

Get rid of the fast idle lever.  Check out the thread in the Tutorials (http://ducatimonsterforum.org/index.php?topic=20142.0) forum. 

I like the fast idle lever.  I was thinking about modding the lever so that the range of the lever pull is able to pull more cable.
If my assumption is that the fast idle works by a separate system opening up the throttle cam, that there are 2 ways to achieve what I want.  either the throttle cam opens up more with the same amount of lever pull from an unmodded fast idle or to mod the fast idle so that it is able to open up the throttle cam more. 

I like the lever over the button because i can chose the rage of the fast idle, where the button is either on at a specific rpm or off.  I remember TOB mentioning using the fast idle as a form of cruse control.  I dont remember if it had an actual mod.

I was sure, but I was also a tiny bit wrong - sorry ;)    (what I'm observing here applies to my S2R 800. YMMV)

The throttle cam does move as a result of applying the idle control. It's a separate cable and you might be able to tighten it for higher revs?

From a safety perspective, I think using it as a cruise control is bad idea, even though I understand the temptation. Just my 0.02.

Why do you think it is a "bad idea"?  I like being objective so your opinion is valued and I dont feel "offended" by your objection.

In regards to the throttle cam, I was wondering more along the lines of if the new throttle cam opens up more even with the fast idle.

All things equal, If i took out as much slack as possible (there by opening the throttle cam as much as possible) does the throttle bodies open up more than stock.

For instance, at max pull of fast idle with stock cams, lets say it opens up 5 degrees. With the new cams and max pull of fast idle, is it greater than 5 degrees? and if so, can you notice how much more?  I know I am being really picky with the details here.  The reason why I ask is that it really dose not take much to rev the engine at 3k rpm, anything slight is enough to get a higher RPM thus making the "poor mans cruise" more "usable" and "usable" in the sense that I can only get my bike to cruse at around 40mph with it being completely stock.

At least on my '01 900 the fast idle mechanism is completely separate from the throttle.

Yes, they both essentially operate the throttle, but they did so via separate linkages. So the cam has no effect on the fast idle lever.

It will have an effect if you eliminate the fast idle lever in favor of the throttle pushb utton thingy off a superbike. But it's barely noticeable.

(And yes, this is all first hand from my own bike wihich has all of the aforementioned things)

On a separate note, the fast idle lever will never be an effective cruise control. It simply doesn't open the throttle enough to maintain a highway cruise. It also can't be made to, since it's mechanism is limited in the amount of travel it provides. For a while I used an old school ignition advance lever for my fast idle control, and it would move the fast idle the full extent of it's travel. Not enough throttle to do more that idle at 5K and cruise at about 30 MPH.

All of this also ignores that (IMHO) it's a really bad idea to have a cruise control mechanism controlled by a completely different mechanism than the throttle. In a panic situation your brain is going to tell you to close the throttle. You're going to have to have the presence of mind to use your left hand to close the fast idle instead.

Bad, bad, bad.

Stick with a friction lock on the throttle tube. They're cheap, and they work.

 ^ ^ ^  what he said  [thumbsup]

OOO

I see. I have been "trained" to pull the clutch in a "panic" situation but i see that it does increase your risk.
