Why would my Genuine Roughhouse scooter be jerking back and forth?

by CTH
(Minneapolis, MN)

My Genuine Roughhouse 50cc scooter has less than 2000 miles and is lurching at 5-10 mph. It idles fine; no problems when up on stand... but when I take off, it sounds like it's running out of gas.

There is a little more than usual blue smoke. No recent changes, oil levels are fine... I'm stumped. Anyone...?

The Roughhouse 50 is a two stroke motor and does not have any valves.

Check the spark plug and air filter, and then maybe the fuel/vacuum line and fuel filter.

Valve Adjustment
by: Jim Zeiser

Time to check the valves for proper adjustment. On a 50cc engine about .002 to .003 inch for both. Also check and make sure that al your vacuum lines are connected.

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...

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.
