What causes a scooter to break drive belts a month apart?

by Anonymous

I put a new drive belt on last month and my new one broke yesterday. What mechanically will cause this?

Belt braking
by: Anonymous

I was told if your variator fan is damaged it will cause the belt to over heat and break.

It sounds dumb but sometimes people put the rollers in sideways when they reinstall them. You should check and make sure they are set to roll out from the crank along the path of the variator. There are videos on Youtube on how to do it. Also, occasionally material from the first belt will wedge itself in the clutch in back. Check and see if any strands have wrapped themselves in there. That would cause the clutch to malfunction.

Drive belts
by: Izzy

Drive belts are just like a fan belt on a car. Sometimes they're good and sometimes they're bad. I would make sure the roller weights are in the proper place and make sure that you got all of the old belt peaces cleaned out from the system.

You have to remember that the belt is under a lot of force and some belts are not as good as they might say. I use a Kevlar belt on my 150cc Roketa trike. I've had the same belt for about 2 years now with no problem. I hope this was helpful.

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.
