Why won't my scooter start back up after I've been riding it?

by Eric Eidson
(Fort Myers Beach, FL)

I have a Tank 150cc scooter. Every time I take it out for a ride, if I stop somewhere and turn it off, it won't start back up until it cools down.

Any idea why that is and what I can do about it?

Coil Wire
by: Jim Zeiser

First check the valves, just to humor me. Then check the coil wire at the spark plug and at the coil. It could be loose, arcing or just plain bad. After that you have to round up all the usual suspects. Change the coil and CDI unit to eliminate electrical breakdown.

Don't think it's the valves
by: Anonymous

I do not think it's the valves because it runs too good. Some times when it won't start, I'll try to start it a few times and it will backfire and then it will start. It almost seems as if it's elect.

Valve adjustment
by: Jim Zeiser

I'm guessing it's never had its valves adjusted. Start there and let me know. .004 inch for the intake and .005 for the exhaust.

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.

Even though most of their posts did not go public, they still cluttered up my website host's server space, jeopardizing my account. I appreciate everyone's contributions over the past few years and I apologize for having to do this.

Wondering why your scooter question never got posted?

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