Hey Guys im Sham from Ireland, bought this kx125 e1 from a friend last week as an old school project for handy money, but cannot get her to rev out fully, thought it was carb needing tuning but there's no airscrew on the mikuni vm35ss, any ideas why it won't rev out? Cleaned carb and jets, too btw.
Is the Power valve opening fully?
Silencer plugged up?
Too big of a main jet?
Carb needle clip set too rich?
fresh fuel?
correct spark plug / gap?
reeds in good condition?
air filter clean?
ignition timing correct?
Check all those things and get back to us.
If everything above is good, you may have a faulty ignition component.

I would check the powervalve next. The parts inside the cylinder were made of aluminum and were known to wear/break over time.
Crank seals also probably need replaced anyway.
