G2 Ergonomics "Throttle Tamer" for the C14

[ridingfar]

I’d heard about a new product called the Throttle Tamer that sounded like true simple genius: A replacement throttle tube that has an elliptical shape for the throttle cable. The effect is that when you first start to twist the throttle it pulls the cable less than normal, making the transition to “on the gas” smoother and taming the typical EFI throttle snatch. After the initial slower throttle opening it returns to normal and reaches WFO in the same amount of twist as the stock tube.

I called the guys at G2 about the C14 and they said they hadn’t gotten a look at the C14 tube to measure it. I sent them mine and they’re sending it back with a couple of Throttle Tamer variations to try and validate their operation. Once I’ve tested them on my C14 the G2 folks will know how these models work on this bike and what to offer us.

The short story is that G2 should know which of their products will work for us in the next few weeks. Worst case is that none of their existing models will work on the C14 and something would have to be developed, in which case it would be longer than a couple of weeks, but after looking at my stock throttle tube they think what they’re sending me will be plug and play.

Stay tuned, more to come soon!

The G2 was a trick the FJR guys have been using for several years.  They use it to slow down the so-called "abrupt" throttle response on the FJR at small throttle openings. 

Seems that most who complain about the C14 say that the throttle response is too slow because of the secondary flys.  The standard G2 will slow the response down even more.  Do they make one with a quicker pull?

Just asking .....perfectly happy with my stock C14.

Great news, hope it all pans out!
It's almost impossable to shift smoothly on my bike, the on off jerky fueling sucks...
I'll give one a try when they get it all sorted out............

I commend the effort, I rode a buddy's '05 FJR that had one of these and it did help that bike.  The twitchy off idle throttle response I felt on the C14 was fixed by adjusting the throttle cables.  The book says 1/8" travel (I think) I adjusted mine to almost no play at all and it is quite smooth.

Sam,

Try taking a little more play out of the throttle cables, I had the same problem when mine was new and that helped immensley.  Let us know if that helped at all..

edit: Oh gee... I just noticed Patrick's (wingfixer) post ahead of mine..  Yeah.. WHAT HE SAID!

[stavee]

Throttle cable adjustment is the thing to do on this bike for smooth shifts. Take the slack oout!!!!

[GTRBO1]

This is interesting. After I posted a topic recently on throttle snatch, I was talking to the guys at morning tea and said "what my bike needs is a ramp or cam type arrange on the throttle to smooth out low throttle response" and Wolla look what I'm reading here. A progressive ramped throttle. I'll buy one.

Don't forget idle (warm) between 1100-1200 rpm.  That and cable adj. make all the difference in the world.  I know, too simple-yet so effective.  Can it be??

That worked for me too.

I have my throttle cables adjusted, it was the first thing I did as the amount of slack was huge, It did help a little...
I guess I'm going to have to pull the flies and add a PC V... After two years and 22,000mi. on a ZX14 the C14 feels like a hound dog..
Jerry, I'm going to be PM'ing you for some tips on the fly removal........

[JamminJere]

Sam,

Like Monty used to say.... "Come on Down!"

I'd be glad to help you or do it for ya.. I've installed a bunch of PC's and pulled the flies on 8 C14's now.. no problems... Stop your decel popping and other quirks if you have any..  Shoot me a pm when you're ready.. if you just need some pointers and are Mechanically inclined.. I'd point you in the right direction for you to do it yourself.  I am able to do above mentioned mods in about 1.5 hours now and that includes all plastic removal/intallation. So it could be done on an afternoon/weeknight if you'd like.

what i found to be the key to smooth connie shifting is very quick shifts.  i only pull my clutch in about a half inch or so (i just tap it) and do a fast reduction in throttle, then right back on it.  with this method, it shifts smoother than a cadillac!  it took me a while to get used to it but now its second nature.

before that, it was very clunky and lurchy (is that a word?!).  i went to visit a freind of mine in florida recently and i let him ride the connie.  when he returned he complained about the shifting so i told him how i do it.  when he returned he said it was a smooth as butter.

taking the slack out of the cables was also a big helper!

My understanding is this ramped throttle helps the initial off idle transition, and there is no change, better or worse, for throttle response after that. So it isn't intended to, and won't help the "slow" low and mid range response that removing the flys seems to improve.

I’m coming off non-EFI bikes – carbs can “feed the closed mouth”, so gas is still fed to the engine with the throttle completely shut. With EFI I have found the off idle transition more abrupt than I’m used to, even with tight cables. I will surely learn to better control this system over time, but if a mechanical modification could ease my adaption and smooth out my riding then I’ll check it out.

And let you know what I find and how it work’s, or not, for me.

Fly's removed on 8 C14's - 1.5hrs. 
I have a Two Brothers slip-on installed allready and will be ordering a PC V and BMC filter from Fuel Moto as soon as they get the mapping done for my particular setup.
We'll have to get together for a short ride and swap bikes, I'd love to see how a proper C14 rides!!!

Resurrecting an old one... I just installed the G2 TT and I gotta say I'm impressed. I had adjusted the cables and done about all I could, but the bike was still a bit abrupt off idle and in low speed maneuvers. The Delrin bushing really makes the throttle as smooth as a baby's ass. Many may not like the ramped model as it does significantly soften the initial throttle response, but I like it. It takes a bit getting used to a little additional twist just before Warp Speed, but the do offer various ramps and there is one that is round like the OEM. Why bother??? Well, did I mention it's SMOOTH... Just for yucks, I set the cruise control and discovered an additional benefit. The Rostra unit is not nearly as snatchy with the G2 as it was with the stock throttle tube. I'm pleasantly surprised since this has actually corrected more little nits that I expected...

I might look into a standard round tube just for the smoothness. I've tightened my cables to take all the slack out of them, and I find throttle transitions aren't a problem.

I've found that the C-14 is really good at clutchless shifting. I can upshift pretty much instantaneously, and if I hit it fairly hard on the 1-2 shift the front tire pops off the ground a bit

Same here! When I first got my C14 I was very deliberate with my shifts and I thought that maybe there was something wrong with my bike cuz my shifts were so rough. Then I found that the faster I shifted the smoother my shifts were. Now it's second nature, I just shift as fast as I can and it's nothing but smoothness.

Oh yeah, the cable needed adjustment too.

[r2t2]

Well, I'm pretty smooth with the clutchless shifts and I am probably up shifting will little or no clutch if would consciously observe my left hand. But this G2 is just so much smoother than the OEM unit. Perhaps just cleaning, relubing and readjusting the throttle would have accomplished the same thing, but as previously stated I had readjusted the cables and that only helped a bit.

YMMV

+1   The G2 unit is a much better designed piece being made of machined aluminum and using delrin bushings. Even without a different cam profile the action is much smoother than the stock plastic tube.

Kinda funny reading this thread.  On my ZX10r the throttle trick was to put in a 1/5 quick turn throttle cam.  Made it feel like the bike had an extra 20 hp.  Also made you learn throttle control, expecially with one wheel in the air  .  I find on the connie im not smooth on slow corners cause I start to twist the throttle and I feel like I have to twist and twist and twist and I run very little throttle slack.  I was thinking about trying to find a 1/5 for the connie to make it smoother.
