Why won't my Chinese scooter start?

by Marshall
(Erie, PA, USA)

There is a high pitched humming noise when the key is inserted. I had to replace the front of it where the headlights are on the harness because it was broken in shipping and when I did this, it started to make this noise. Even putting my old part back on and it still does this.

Chinese Nightmare
by: daniel

I purchased a 260t-4 super scooter in april2010 it ran great for 324 miles then stopped running.I have replaced the coil 3 times a new cdi new starter spark plug. I ordered a coil for a 250 have not received it yet. but I got it running for about 3 Min it shut down again this is a wonderful scooter I love riding it.

So I took out the spark plug and while putting it back in stripped the threads so I bought a new plug I tapped out plug threads put plug back in still will not start I can't figure it out unless might have gotten a piece of aluminum under the valve.

Can anyone help me?

need a little more info about your condition..
by: aaron

I need a bit more info on a few of conditions before I can respond to some possible causes and/or things thing that might be of use to you.

1. You said when you insert the key, you get buzzing sound, do you mean when you turn the key on? and or to other positions (if more than on and off) if you get the sound just inserting the key and not turning it that would be strange since it isn't really doing anything till you turn it.

2. Is it a buzzing sound, humming or clicking sound? Clicking would point to solenoid relay switch... humming could be stuck relay type component and buzzing could be pezo electric buzzers, horn or turn sig indicator components.

3. You said some electrical was damaged in shipment, did everything work properly at first then and fail after that or did you replace the damaged parts and have never actually verified that everything worked properly to your knowledge... not knowing this makes it difficult to give any possible things to check that would be of any value to you. And would more than likely have you checking real things for possible probs. that are unrelated to what the real issue might be, i.e., if you know everything actually worked properly and the prob you mentioned started after replacing some damaged parts you would focus your search from that point. But if you can't verify that, then you would start your search for the possible issue from a completely different point.

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.

Read our review or go right to Amazon.com to buy this highly recommended Battery Tender Jr NOW...

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