Hi Not sure what model you have but if its a JONWAY - YY125T-31 MADNESS, scooter then its a 4-stroke, air cooled 125cc.

Hope this helps you

i have had to repair one of these with the same problem
and the main problem with all Chinese scooters is the electrics
first thing see if you have a spark first if you have a spark
then it could be your carburetor
other than that its your electrics
what i had to do was take the scooter apart
chop all the junction blocks off the wiring loom
the match the colour codes together and solder the wires together

i know that sound a bit extreme but it makes it more reliable
but look for a spark first

What year is it ? Is the cylinder-head height or shape capable of holding a rocker shaft and valve ?
