Fast throttle cam. Get one, just go and get it!

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.

Ahem. Pictures.

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 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.

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