Twitchy throttle

Seems my ‘14 wee is a bit twitchy at low speeds. Anyone else experience this?

Have you checked/adjusted your throttle linkages and free play? The 650's are known for being incredibly smooth and linear, twitchy throttle is more of a 1000 thing.

I just bought it Saturday. It has 1500 miles so its likely new and needing adjustment. I have a Vee and its always had a PCFC module so never any twitch.

It only occcurs at low speed <15 mph

I have the same thing on my '12 Wee and searching the forums it seems to be a common issue. The most common theory about the cause is that the fuel map is a bit lean at low rpm. There are many solutions floating around, from adding a resistor in the temp sensor (makes the bike think it is colder so kinda puts the choke on, but it is on all the time...) to more sophisticated "smart" electronic add-ons to do the same thing but better, and through to Power Commander, with Throttle Tamers on the side. My solution has been to rest one or two fingers on the top of the brake lever to steady my hand a bit - seems to be working fine so far.

One action you can take that will not eradicate the abruptness at low throttle settings, but will help you to overcome it. That is to take as much slack/freeplay out of the throttle cables as possible without affecting tickover. My Tech did that with my 1000DL and it helped.

I find when I get that twitchy, lurky feeling, something needs adjusted. Throttle cables and/or chain are the usual suspects.

+1! Just be sure to turn the handlebar lock to lock while feeling for free play. If there's any tug on throttle cable, you may end up with Toyota.. aka unintended acceleration.

The other important thing: make sure your chain sag is set correctly. Too much sag can exacerbate twitchy throttle, but be sure it's not too tight either.

I think it's just nature of the bike, fuel mapping. At slow speeds the throttle is like a light switch, either on or off, so you're either accelerating or decelerating, very difficult to maintain a steady speed. It helps to ride in a higher gear and sometimes I find myself working the clutch to smooth it out. As others have mentioned too much throttle play makes it worse.

Brakes can also be used to smooth throttle tip in. I'm so used to trail braking and getting on the throttle as I'm easily off the brake(s) that twitching is never an issue really. In a straight line (say in slow town traffic), light application of rear brake can be used before applying throttle and then easily off the brake. Once this becomes habit, you can make any bike feel incredibly smooth. Of course there's nothing wrong with clutch feathering too.

And if you think this bike is twitchy, have a go on Yamaha FZ-09.. particularly 1st model year. Talk about ON/OFF stitch!!
