Acceleration problem Aerox

[SpeeJ]

Hi, i'm new in this forum and i don't know much about scooters, so don't blame please .

The problem is that my scooter won't accelerate in the beginning but it revvs up at 20km/h and then it goes pretty good but if i slow down to 40 km/h it wont accelerate again, it's horrible to drive in traffic and go up hills.

Right now i only have:
Gianelli Reverse
4 gram rollers.

On the other thread i found pretty similar problem, and then the spark plug wasn't long enough. So maybe you can find some other problems and at the same time tell me the, what could be the right size for the spark plug

hi there

I suggest you change the contra spring, which is located between the clutch and the torque drive, to a more strong one and the small clutch springs

hope it helped

cheers

Okay, i got my new spark plug and it didn't help, now i must hope on contra spring and clutch springs .

What should i buy next? Carburettor or a variator?
