Why does my Urban Tank 4 stroke scooter sputter or bog out?

by Chris Voss
(Chincoteague, MD)

We have cleaned the carburetor and cleaned the air filter on our Tank Urban scooter. The old air filter was soaked with gas and I also changed the spark plug as well.

The scooter still bogs on open throttle and the air filter still gets soaked with gas and is still running poorly. Not to mention it runs through gas quickly.

Any suggestions?

I am not familar with the Urban Tank. But looking at the reviews there are several models.
Which one do you have?
Unless the engine is backfireing how is the gas getting to the air filter?

Is your carb cracked and it spraying back?

Do you have an electric fuel pump? My understanding is these push out a lot of pressure and require a regulator to to added.

It sounds like you might need a valve adjustment, or you might need to adjust the air intake on the carb.

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.
