Why does scooter die after full throttle for a minute or two?

by Jeff C
(Fort Lauderdale, FL)

I have a 2000 Honda Scoopy 49cc scooter. Starts first time every time. It runs good when throttling up. If I ride it at full throttle for about a minute or so, it drops power almost as though I let go of the throttle completely.

If I release and rev the throttle a few times, it sometimes recovers... other times, it just shuts off and I have to restart it. It seems it only happens when running wide open for a length of time (30 to 60 seconds). Anyone have any thoughts? Thanks in advance

Maybe over heating
by: Gary

Another possibility is it's overheating and causing fuel vaporization. If the rings are seated (past engine break in mileage) you might try draining crankcase oil and replacing with synthetic oil; scooter should run cooler even at WOT. May sound far fetched, but it worked for me, it does make a significant if not dramatic difference.

Fuel Filter
by: Jim Zeiser

Take out your fuel filter from the system and see how it runs. If it runs fine you have the problem located.

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...

Wondering why your scooter question never got posted?

Chances are, there is a good reason. Did you...
