50cc motors have QMB serial numbers on the left side next to their side stands. 150cc motors have QMJ serial numbers. 250cc motors-I'm not sure, but it's not the other two. Besides, a 250 is a big scooter and comes with two different motors.

Type of oil.
by: Izzy

The size of the motor shouldn't matter as long as you know if it's a 2 or 4 stroke. If you have a 4 stroke with high mileage, I would use a 10W 40 full synthetic. If it's a 2 stroke, I would use a high grade synthetic blend oil.

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.

Attention!

ATTENTION! I have had to delete the Scooter Forum for this site, unfortunately. Despite my best efforts, I could not adequately prevent daily attacks by hackers and spammers. 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...

If you "checked yes" on any of the points above, then I've deleted your post. Sorry, but I have standards. Feel free to re-submit, following the instructions I have everywhere on the site.

Also... all submissions have to be reviewed by me, and I am currently backlogged. Comments go live without approval, but still take 30 to 60 minutes to show up, so don't repost them, please.
