Modern Vespa

Hi folks,

The throttle on my LX125 has a fair amount of play on it - prob more than it should have especially when compared against partners LX50. Hers has about 5mm, mine about 10-15mm.

What do I need to do to rectify this?

Also, Ive noticed my vespa isnt as responsive at pulling away as it once was. It used to be off like a shot in days gone by, but now it kind of hesitates pulling away as if Im towing a truck.

Are these thing related?

help would be much appreciated.

Cheers

Check out the thread 'Throttle Play...A flawed topic' from Thursday, Sept. 10th. Then, don't ever bring it up again.

Ill have a look.

Thanks

They could be related if you're not getting a full range on your throttle, meaning you aren't able to achieve a true full throttle.

To take the slack out, go find your carburetor under your seat and under the helmet compartment. With the bike off, operate the throttle on the handle bar and watch what happens on the carb. Near the part that is moving there should be an adjustment screw to take some slack out.

If it's been 6,000 or more miles since you've done a belt/roller change, it could be that your roller weights have flat spots. That can cause poor off the line acceleration.

Belt and roller have been done, so must be just the throttle.

I have the same problem (not the throttle play). So did you find a solution?

Hi there,

No, I havent solved the problem.

Its wierd, but as the weather temperature has fallen over the last month or so (over here in the UK) the LX seems abit better - not by much I may add.

I think when the time comes, Im going to get some lighter rollers and Polini variator. I had these on my ET4 and they def increased performance in the acceleration area.

As for the throttle play - its slowly getting worse, but Im gonna have a go at that soon.
