Why does my scooter suddenly decelerate and stop when I'm going uphill?

by Lina
(Gibraltar)

I have a Yamaha Aerox 50cc scooter... the engine still runs but the scooter just stops when going uphill (this has happened on flat planes too but usually I just accelerate a few times and the scooter starts moving, but this was not the case when going uphill).


Can you tell me what might be happening and how I would go about fixing this?

Scooter losing power up hill/straight away NEW
by: Jimmy

Scooter losing power up hill/straight away. My scooter starts fine runs fine until I get up to top speed then it just dies, it don't cut off but I come to almost a stop then hit the gas and it goes again, Answer is Weak torque spring in rear clutch bell. If ya scooter wheel turns rather fast while at idle, Its ya spring :P

Scooter runing trouble NEW
by: Scooter#3

I have a 2014 scooter i got used, and it
will take of good, then as it gets up to speed, it starts slowing down all the way to almost pretty much a stop and dies. Then takes a minute to restart, just for it to do the same thing. I honestly dont know why its doing that. I just want advice for what it could be.

my tao tao did the same thing when i got it. After a little searching I found it was vapor locking. I drilled a very small hole in the gas cap and always loosen and retighten the cap every day before riding. Never had the problem again.

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...
