I believe that the idle may be set high on my LX-150, but the scooter runs well. When warm and idling on the centre stand, the rear wheel does spin about 1 revolution per second. My only problem is that I can barely get 50 mph out of the scooter (mind you it is hauling all 200 lb of me with it ). My question is, if I turn down the idle a wee bit would that further lessen my top speed, or would I be wise to just leave well enough alone?

Your idle has nothing to do with top speed. They are on two totally separate circuits in your carb. They should have nothing to do with each other.

But there may be some problem... I can easily hit 50 (on the speedometer) on a flat surface on my unmodified LX and am about your same weight (okay, a little more). I was just doing 45 with a 115 lb. passenger earlier this afternoon na ddid not have trhe throttle opened all the way...

On the speedometer, I reach 60 (90ish kph), but was clocked at 50 by my wife, who was following behind. That is where the 50 came from. Is that still out of the ordinary for an LX-150?

According to the technical comparisons for LX150 60 should equal 55. I checked on LX150 with my I5 and its about right. Verified GPS with my Vette certified speedo - it was only off 1 mile per hour once the vette got into triple digits.

The Vespa speedo gets less accurate the faster you go.

Check here for the technical details
