I've got a little jerkiness in the throttle from idle. I tightened the chain and the jerkiness is still there. I read somewhere else that slack in the throttle cable connection to the throttle bodies will cause a jerky throttle response. Anyone else have to deal with this? Difficult to fix?

Define jerky throttle response. Are you trying to run the engine below 3000rpm?

Are you using the clutch? If not, that's your problem. Lower speeds require clutch slippage and more revs. If you are using the clutch, it's the clutch or your use of it that is suspect.

It sounds like you need to check your TPS (throttle position sensor) setting. Also, adjust your throttle cables until you have about 1/8" freeplay. Do a throttle body synchronization too (you can make your own manometer). I would do all 3 of these. All of these are easy to do if you have some mechanical ability. Do a search on this forum for threads that deal with these issues and have instructions.

If you don't have a service manual, I can e-mail you one. A small piece of wire can put your bike in "dealer mode" to check the TPS setting on your LCD display. Let me know if you need help on this.

Not meaning to resurrect old threads (It's not *that* old!)... but I'm experiencing something that I would describe the same way...

I've noticed it in 2nd gear quite a bit... When I'm cruising at about 50 kph, bike at 4000 to 5000 rpm, if I let off the throttle all the way, it feels like an on/off switch... gently turn it back on, and nothing, until WHAM it feels like I get jerked forward quite a bit... As noted above, this is at speed, and decent RPM's... It feels like the throttle itself is going from completely closed to 10% open in a non-smooth manner... everything after 10% feels analog in nature, nice and smooth.

I've adjusted the throttle cables and done the throttle body sync... Is there anything else that might make this feel better (On an 08 Vee)

In manual you will find that there should be between 2 and 4 mm of play before engagement so throttle won't open inadvertantly when turning tight corners.
It is a bit of a pain as it does feel like an on off switch.
I try to guage with my wrist just as the I return to idle and not let her close completely....not to successful.
Unless you adjust all the end play out which you are not supposed to, I believe you will have to live with it.
Makes it a bit hard for gracefull throttle applications sometimes don't it.

throttle adjustment

just did mine and it did clean up some of the "hard to be smooth" stuff in the wee, like riding slowly across a parking lot ..there was not much adjustment left, but it has made a diff. Simple to do

I ended up adjusting my throttle cable as well as adjusting my riding habits. I took out the slack on my throttle cable by feel; I'd set it, then swing the bars back and forth to check whether there was any different in play, then adjust from there. Nevermind the manual - do what feels right.

In terms of my riding habits, I slowly roll off the throttle now instead of just "snapping it down". I still end up in the same place (rolled fully up) but I do it in five seconds instead of one. My Wee is nothing like the Shadow 600 that preceded it: it's a lot better. It will require more from you as a rider but it'll make you a better rider at the same time.

Yes, it's worth taking the slack out of the cable. From the factory mine had waay too much slack.

Just be sure to test it full left/right lock (no rpm change) to make sure it's not TOO tight.

Make a BIG difference to "off the line" response - not that I'd want encourage you to blow away litre sports bikes at the lights ;)

I added some slack to be able to keep my hands on the grips when using an electronic cruise control and I have no problems with very slow speeds. I like to play with traffic situations at stoplights by keeping my feet on the pegs as long as possible. Minimizing slack will do nothing to help throttle control unless the cable is sticking. If you're doing it right, the throttle should never be all the way off except when you are decelerating by coasting. For very low speeds, the rpms need to be kept well above idle and speed controlled mostly with the clutch and rear brake.

+1 on that. I initially felt that the throttle was more of an on off switch until I got used to riding the Wee. (I barely made it out of the dealer parking lot the first time I rode it but that's another story:scared: )

I almost learned the hard way that you don't close the throttle going around a corner in a parking lot:eek6:
