Hello. new here on the forum.
I've just bought a 2001 125 ec for my girlfriend to start riding.
It runs nice at idle but very bad as soon as you open the throttle, but if i twist the throttle wide open it hits hard and revs out nicely.
My latest idea is about the power valve so i post this video to get your opinion,
is this power valve moving properly?
