You may need to adjust the fuel/air ratio. There is a small screw under the pull starter facing horizontally (its behind the plastic air filter cover, but accessable) adjust either clockwise or counter clockwise in small increments and give it gas and see if it dies or boggs down. Also check that spark plug is clean and not fouled, and air filter is clean and olied.

SOURCE: I have a three year old Piaggio 50cc Zip scooter.

I have had the same problem with my stepsons zip 50 and have done all the usual checks. The solution is from a piaggio technition. Take off the air cleaner and housing, start the scooter and bring it to the point where the engine dies. At this point spray easy start or a gasoline spray direct down the carb intake. If the revs pick up, you have a lack of crank case compression and the most likely reason is worn oil seals on the crankshaft. It sounds odd but the worn seals cause all kinds of strange problems.
Thats 2 stokes for you. Hope it helps, good luck

SOURCE: problem with running of scooter

Sounds like it is running too lean. Look for an air leak around the carburettor manifold.

SOURCE: cant get my 50cc scooter to fire up-no spark. any

  • Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
  • Is the handlebar kill switch on? Is it shorted out?
  • Check the fuses.
  • Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires?
  • Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing.
  • If still no spark, get CDI system and coils checked at the dealers shop.

My hyosung hyper 125 scooter won't even try to turn over the engine - it was running when I got it but now won't turn - could this be the solenoid or the switch?


Hi, Janie and the usual suspects are:
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Discharged battery, needs to be 12.5 volts or better and be able to pass a load test if necessary.
4. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Tip over sensor needs a reset.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand or clutch pull in switch/sensor.
9. Starter control circuit, relay, or solenoid faulty.
10. Main fuse or circuit breaker may be blown or faulty.
11. Check for engine trouble codes.

I've got a 50cc scooter does 40 top end Good on acceleration I've put a new plug lead and 6.5 rollers in it and a new belt, but in between acceleration and top end its slow any ideas?


Hi, Nathan it's only 50cc what do you expect? and how do you know it's slow? have you raced any other same make and model and lost? for this situation, I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry.

Engines dies when going up hill


It isn't a fuel problem, it is a power problem. Any bike will slow down on a hill. The bigger the engine, the more power is available to maintain speed. 50cc just isn't much power to pull a 150 pound man up a hill.

I am assuming the scooter has a two stroke engine. If it is a four stroke the valves may be needing attention. But even with good valves, 50cc just isn't a powerhouse of an engine. If you want to be happy, trade the scooter in on something 125cc to 200cc. You will feel better about your ride and be more respected on the roadway.
