Any idea why my scooter chain and tire don't turn when it is running?

by Anonymous

My scooter starts, runs, and revs but for some reason the chain and tire don't spin. Everything works but my tire is not getting the power.

Anybody have any ideas what's wrong?

I would pull off the side cover, start the scooter and observe things. The belt should start climbing up the pulley in the front and sinking into the pulley in the rear. If the belt isn't climbing in the front the roller weights are sticking in the pulley and you need to take apart the pulley and see if the rollers or pulley are damaged. If they are doing what they are supposed to be doing and the wheel still isn't spinning then there is something wrong inside the clutch in the back. Either the shoes are worn or the arms are sticking and need to be cleaned and lightly lubed. There are videos on how to disassemble a clutch on Youtube.

How to fix

I have the same issue... I'm really not mechanical but If I were to give it a try how would I fix this? I'm trying to fix this today.

Scooters don't have chains. Under the cover on the left side is a clutch and variator. If the shoes inside the clutch aren't making contact with the bell housing power won't be transferred to the wheel. Also if the weights inside the variator aren't moving out, the belt won't climb up and make the wheel spin faster. Are you sure your drive belt isn't broken? Otherwise it sounds like a clutch problem.

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.

Wondering why your scooter question never got posted?

Chances are, there is a good reason. Did you...
