My MP3 400 has a lot of throttle slop and I've searched here but couldn't find anything specific on help in that area.

There are two cables and I'm sure it's the "pull" (top cable) but not sure how to adjust. Is it required to take the light metal gray shield (with cut off switch, starter button) off to adjust the throttle?

Thanks

If it's like the 500, then I believe that you can adjust the slack a the lower end of the cable, where it meets the throttle body.

No. The adjusters are under rubber covers in line with the cables at the twistgrip end. I can't recall whether you need to remove the top handlebar cover to get at them but I think you just slide back the rubber sleeves. You do need to leave enough play to allow the throttle to snap against the stop, even on full lock.

Yes so they are. Maybe my memory is playing tricks but I just don't remember them being there on my early model mp3 when I changed the cable.

Ramblerdan.....that looks right. Thanks

I checked my workshop manual PDF and found the same pic. Now....how to find that spot on the scoot and get to it. Looks like it's near the air filter but hard to tell from the pic. Do you know how to access these adjusters?

under the seat there is a access panel to the top of the throttle body. open this panel and you should be able to see the cable.

Thanks all.

Actually the adjusters are reachable from the Left (belt) side of the bike in front of the air filter. Found the problem was the lock nut was loose. Used the adjuster, tightened down the lock nut....done!

I just went out to the garage and took out all excess play in the cable. It was a 2 minute job, no tools needed. I didn't expect anything to be that easy on an mp3 You did the hard part finding that adjuster for us and I thank you for it.
