throttle on-off jerkiness

[martin_14]

many times it has been asked about the abrupt on-off throttle response from this bike, and among other solutions (including throttle tamer and such) it is always suggested that you should tighten the play on the gas cable. Well, to you all smart @sses out there, let me tell you something: you're right!!! I have been experiencing this since day one and I adjusted my right wrist accordingly and, for the most part, I've been able to keep it down, but it never stopped bothering me, and during the last 3 or 4 thousand km it got a bit worse, maybe because of the high temperatures in which I've been riding (100°F). Last week I did the 30.000 km service and the mechanic at my dealer (not a "stealer", because they are great: listen to me, charge me fairly and work professionally) specifically told me that it was a bit loose and adjusted it. Now it's not perfect, but it is much better.
There.

With that much power on tap it does seem like a light switch sometimes. 
For me smoothness just came with experience riding the bike.

Each bike I have owned were different in throttle and clutch response, you just have to get used to them,, making adjustments helps, but each one is different.

[Boomer]

Coming from a Carb bike to an FI, the change in jerkiness is pronounced.
So much so that sometimes I am loathe to open the throttle whilst cornering in the wet.
Since I've had the PR3s my confidence in the wet has grown and I have managed mostly smooth off-on throttle transitions.
However, I will have a look at the throttle cable adjustments tomorrow as it can still be smoother.

The biggest problem with FI motors is that with zero throttle, you get zero fuel injected.
With carbs there is always some fuel going through.
So the transition from no fuel to some fuel is a bit of a jolt.

A Throttle Tamer will fix it.  I put one on my bike before pulling the flies and it made the throttle transition very nice.

I'd like to see some of you with the "quarter-turn" throttle mods we put on our ZX14 beasts

+1 on the Throttle Tamer. Not only does it help with throttle snatch but it's action is smoother becasue it has self-lubricating Delrin bushings inside.

Martin, I have to agree with you.  Mine has also been of 'light switch' quality since day one.  This morning was the 4th time I've adjusted it (18,600 miles), because it just seems to keep getting loose.

I've always tried to follow the FSM instructions to the letter, but those instructions don't really provide any confidence level that it's been done with the results they expect.

This morning, I just said screw it, and adjusted ALL the play out of the throttle, and the off to on transition is better than it's ever been.  It didn't affect the idle, so I'll just leave it there.

There's still a huge jolt in second gear under some conditions, but nothing like it was.  So far, 1st gear is where I see the most improvement.

Of course the real test will be down hill through some 10MPH switchbacks.  I'll let you know after I try some of those.

+1  I had a very hard time adjusting, coming from a carb ZRX to the Concours.  (Who am I kidding, I still haven't adjusted yet).  I adjusted the play and it helped some, but it is still very different from what I am used to.  At lower RPM's ( < 3k) it isn't an issue... but at higher RPM's... whoa.

How difficult to install?

[tonedeaf]

In normal to moderate riding I feel like I have a handle on throttle smoothness, I especially feel comfortable with throttle roll-ons coming out of medium to broad sweepers.

However, I tried my first drag race last week with a Triumph Speed Triple. The revs built so fast I was late on the shift and hit the rev limiter in four gears. (Still managed to stay with the Speed Triple -- which is a marvelous scooter, BTW.)

How difficult to install?

Easy - just a few minutes. Same as removing and reinstalling the stock throttle.

[Conrad]

How difficult to install?

Very easy. The hardest part is taking the grip off, and that's not hard at all. A bonus is while you have it all apart you can go ahead and lube your throttle cable.

Has anyone put a Throttle Tamer on a 2010+ bike?  Just curious what the case may be with the heated grips?  I seem to recall reding somewhere that this may be an issue?

I bought one, but haven't tried to install it yet.  I was wondering what the difference in ramp angle is, and if you could just shave down the cable guide slot to improve the stock one.  One of these days I'll get time to look at it all...

I have a 2010 with heated grips. I bought a Throttle Tamer but it was the wrong model - got confused with model numbers. Anyway, I examined the TT and thought to myself I can file a groove that would do the job just about as good as the TT. So I went to hardware store and found the right file and filed away. Jerkiness is mostly gone. Much, much better that stock!!!

I have no idea how to get the heated grips off the 2010 model. All suggestions posted on any 1400GTR forum must be for the unheated grips cause the instructions don't work for me.

Mmmmm.... throttle snatch!

You should post pictures and a how-to and such

There. 

Mounted the Throttle tamer and adjusted the play out of the throttle. It helped some. Recently I have been practicing throttling on very lightly before entering the corners and modulating my speed with breaking. This allows me to have the throttle open past the on/off stage and allows me to progress smoothly throttling out of the corner without the initial on/off jerking.

Anyone else out there tried this??
