Why is my newish scooter running rough at idle and sometimes even stalling?

by Mark

Also gas mileage went from 100mpg to 84 mpg. Yes it sat at some point (I bought it in 2011 with 900 km on it and it is a 2008), but from 900km to about 1600km it ran great.

Once I got to around 1700km it started running rough at idle (though not every time at first), sometimes stalling even after driving over 10 miles and the gas mileage went down by almost 20 mpg.

I don't notice a loss of power once I get going, it seems fine. It is a Lambretta UNO 150 (4 stroke 150cc) scooter.

Perhaps this is a separate problem but it is a little hard to start on a hot day (though starts right up if it's been in the shade for at least an hour) even with a new battery.

Problem Solved

It was a fuel line leak near the fuel filter. The crack was all the way through half the hose. I found it by moving it. When gas started gushing out, I knew I had found the problem.

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.

Read our review or go right to Amazon.com to buy this highly recommended Battery Tender Jr NOW...
