Could my Tank touring 250 cc scooter be vapor locking due to the heat?

by Nora
(Houston, TX)

The scooter starts great, runs great, but if I shut it off, it will not start again until several hours later. We tried removing the gas cap & replacing it, but it doesn't work.

The problem is ongoing. We live in Houston and it is very hot here; we assume that is part of the problem. Can you help?

XY260 similar problem

Bill did you ever find out why you had no fire? I'm baffled.

XY260 similar problem
by: Tim

I have a Canadian Chironex which is the same as the XY260. I have the same problem. I put a fan on the rectifier and it seemed to help unless it was really hot. If it started it would be fine, but shut it off and let the heat build up in the cowling and it wouldn't. I suspect the CDI might be the problem.

No fire at plug
by: bill mink

I have a xy260 with a similar problem. Mine won't start if it's warm outside... no fire at plug. If it's cool, no problem starts up. Let it idle a very few minutes and it shuts off... check plug, no fire! HELP... I'm missing riding season...

Could be Something Else
by: Jim Zeiser

Tanks are notorious for balky electronics. I might suspect a bad CDI in this case. It could be heat sinking when you stop and need the time to cool off to start later. Check the spark when it won't start and see if you have any. This will tell you whether or not you should look in the ignition circuit.

Vapor locked
by: Izzy

This doesn't sound like a vapor lock. It sounds more like the carb is dunning to lean. I would try turning the fuel screw out 1/4 of a turn then check the spark plug. It should be a dry brownish color. I hope this helps you out.

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.
