Can anyone tell me why my 150 scooter cuts out while riding it?

by Jeremy Brininger
(Middleburg, PA, USA)

I have a 150cc Wildfire touring model 2006. It starts and runs fine and when I go down the road it will be fine for awhile and then all at once it will cut out and I have to pull off the road and restart it and then I can go for awhile.

Someone told me it was the cdi box but I have replaced it with a brand new racing cdi and it still does the same thing. Can anyone please help?

mine doing the same thing NEW
by: Tim

I have a brand new 150cc Jonway with 300 kilometers on it and it is doing the same thing. I put about 150 out of the 300 kilometers on it today cruising around and breaking it in. After cruising along it would start to lose power and then completly die. It did it four times toady and it wouldn't start back up immediately and I would have to wait about four minutes then it would start and run fine for about another 20 kilometrs.
I drained the gas tank and filled up with fresh gas then going to change the fuel filter tomorrow and keep my fingers crossed it works. The shop has allready cleaned the car for me last week when it wouldn't start at all.

scooter cut our while cruiseing NEW
by: kennith

this is my third summer,with my 150 cc yes mine has done that twice-im thinking,maybe the float in the gas tank-some of them are made of some type of what appaers to be a cork type float,it may be breaking up in the tank or maybe the gas filter is just getting dirty and clogging.

Up date: 150 Wildfire scooter cutting out
by: Anonymous

OK, I replaced the coil and it still does it but what I noticed is that it happens more when I open the throttle all the way for a period of time. You can feel it buck every once in a while when just cruising.

When it completely cuts out, I let off the throttle and just start to ease back on the throttle and about half way open it will backfire through the exhaust and start to pick up again.

It gives no warning when it cuts out; you can be cruising at 55 and all of a sudden it just dies and if I feather the throttle, it will normally come back.

Is there any other suggestions? I need help I am at a loss right now.

I would suggest checking the valves too.

The Coil
by: Jim Zeiser

You could replace the ignition coil. It sounds like a heat breakdown problem. Personally I would go over the scooter, unplugging and re-plugging all the connections. Sometimes there is a corrosion build up and doing that cleans the plug and solves 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 to buy this highly recommended Battery Tender Jr NOW...
