Why does my 50cc Peace scooter bog down when I give it gas?

by Jonathan
(Baltimore, MD)

When I kick start my Peace scooter, it will run, then cut off. Then it will take about 30min to get it started, but though it starts back up, when I give it gas, it will bog down like it's not getting any gas.

After that, when I try to ride it, it won't reach 35-40MPH like it used to. What can it be? I changed the oil and spark plug, but it still does it.

Running then dying?

Check the valves and adjust them to proper clearance. If set too high, they could be getting hot causing scooter to bog down and shut off.

I Had The Same Problem w My 50CC
by: Anonymous

It MAY be the same prob I had. It would run fine then want to bog and cut out when I gave it gas. It turned out the petcock was bad ( this is the thing that regulates fuel coming from the tank down to the carb ).

This is how you can check to see if your scooter is bad too. Remove seat, keep it lose so if bogs on you and cuts out, you can can pull over, (keep scooter running) if it will runs still, pull the seat off unplug the gas tube just below the little gas filter thing and have a plastic bottle with you. If gas is not shooting out as u pull it off into the bottle u have there to catch it, then its a problem w the petcock.

You can also try with it off to suck the vacuum line, if fuel doesnt flow into a bottle from what I just told u to unplug the petcock is bad. The line u are going to suck looks like its coming from the back of the scooter down to the right side of the intake manifold (the L shapeed thing holding the carb on the scooter) it's on the opposite side of the fuel line.

Petcocks are only $10 online but a bitch to remove, u have to take the gas tank out and everything. Until you can replace it, carry gas on you in a hair dye bottle since the spout is pointy enough to let u squeeze gas in the fuel line until its full. Petcocks seem to work on and off when they give u crap. It sucks.

Sounds like flooded engine
by: Jeff C

Possibly getting too much gas not enough air. After 30 minutes the flooding clears and you are able to start it again. Clogged air filter maybe?

Vacuum Line
by: Jim Zeiser

Somewhere, someplace you have a vacuum line that's either off or broken and letting air get in. Start the scooter and listen for hissing. Look hard for mysterious hoses or open plugs that are sucking air when the scooter runs.

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...
