Hey guys,
I finally decided to figure out why my scooter vibrates like crazy at higher speeds.
My scooter is an 08 Agility 50
I did not modify this scooter myself but it does have an aftermarket CDI, Polini Variator, and a malossi clutch.
The belt is a Kymco Bando belt.
When I had the engine running and gave it some gas I noticed the belt was vibrating up and down like a sine wave and thats when the noise started.
My question is, should I buy the stock Kymco size belt which (from research) is 729 17.7 30 ?
Or should I go with a longer belt?
Anyone have some suggestions?
Thank you much in advance.

Thats belt slap. Some of the Vespa's have a big pulley in the middle to keep it from happening;

Not sure there's anything else you can do about it. Resonances in the system cause it so any change
could make it better or worst...

So a newer tighter belt would not change anything?

have you measured your belt,. I have three belts and they are a little different size , each one of them,. one of them is 6 mm. longer then the others,. but I must say the more miles I put on my scooter,. the smoother it runs ,. 32,000 km. and running

Whats the best and proper way to measure it?

check and see how the rollers look and see if you have any flat spots. it might be time for a new clutch my 07 agilty got a new clutch after 4 years.

check the wifes sewing kit, look for a tailors tape,. cross check it against a steel tape, and measure around the outside of the belt that will be your first # then measure across the top of the belt thats your second # the last # is angle of belt usually 30 degrees

X2 the degrees of the belt is what most likely wears out frist on the belts. If so its time for a new belt.
