Abrupt throttle response near idle in the twisties ...
« on: May 12, 2011, 04:21:24 PM »
I've had my 2010 C-14 since December. Recently I have been noticing abrupt throttle response when I try to come on the gas smoothly after slowing to start a turn in tight hairpin-type turns. I'm not sure if it's something I'm doing wrong (like maybe letting the engine wind down too much) or if something is amiss with my bike.  Even when I concentrate on smooth throttle inputs, the engine seems to surge to life a little too quickly.

Is this a problem with my bike, or do I need to do something differently?

No, this is normal operation on newer vehicles that shut off fuel supply when you are not on the throttle. Its their attempt to save gas and reduce emitions. We all get it. You'll get better at compensating for it.

The only other thing I can think of is make sure your throttle cables haven't stretched and are adjusted properly.  Might help out some.

Typically we've found the adjustment to be somewhat loose from the factory.

Seems to me that my 2010 C-14 is less abrupt when in the ECO mode.

What Jim said, and to add (mind you NOT a flame), also the roll on/off/on plays an important part.  Have you ever experimented with honest trail braking?  Still some throttle input while using brakes?  Helps maintain suspension set and healthy rpms during cornering, allows for a much smoother transition from apex, and on.

I jusk bought my 09 a few weeks ago and had the same issue. I adjusted ALL slack out of the cables. It didn't make the problem go away completly but it did make a huge improvement.

Check the slack in the throttle cables as others have suggested. Worked wonders on mine.

Try a lower gear, keep the rs up.  Quicker shot off of apex/point of power.

Agreed with the advice to keep the Rs up. I am still in the break in mileage range. Very frustrating to keep it under 4k.

I noticed defenite improvement after installation of a throttle tamer as well as the techniques listed.

+1 on the Throttle Tamer --put one on my sons Ninja 650 ,which had pretty abrupt fueling off idle.

Noticeable difference!
