More power for my scooter?

by Artist Bob
(Half Moon Bay, Ca)

I recently bought my first scooter. I had ridden a motorcycle (briefly) before. My new scooter is a delight in every way. It is a Chinese built JMSTAR 150cc purchased at a dealer in San Mateo, CA.

I am a big guy and I'm finding that I have to drive full throttle to keep up with the auto traffic on the two lane coastal HWY. The autos run 50 to 60 mph. I would prefer to travel along about 40ish to enjoy the scenery, but the auto drivers are in an all-fired hurry to get from one point to another so they line up behind me gnashing their teeth. I don't want to make any scooter-enemies.

Is there anything I can do, change, add on that will get a few more ponies out of my steed? I've seen exhaust pipe adds that promise more power. Is there anything to their claims? And would it help?

Thanks, Kathi, for making this site available.

More Power
by: Jim Zeiser

Scooters are like anything else. Hotter cams, better exhaust, bigger carburetors, removing the stock air filter and putting on a sock style for freer breathing. Also a Prodigy Variator from Ebay and experimenting with weights in the variator will yield some more top end and acceleration.

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! 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.
