i know this is the wrong forum but i'm not getting much response from performance tuning.
I've rebuilt my za50 5 or 6 times over the past two days and when i finish, the bike starts up great and then revs really high when i open the throttle but the back wheel hardly spins at all.
I've tried flipping the second gear clutch but now I put everything back the way it was before I changed anything and it still doesnt work! Just revs high and doesn't go. its not engaging.
in DESPERATE need of some help here
