Hi guys,cheers from Portugal,i Have a small(big) Problem,here it is! When I do key on , the motor rotates anticlockwise(dont do the clean test and stops at the 90° position (270° anticlockwise from top position) and shudders briefly in this position and just stops. Is this normal? With the cables on, the motor still only tries to turn anticlockwise making the right hand cable go tight and the left one slack, sometimes causing the left hand cable to pop off out of motor pulley. When the right cable goes tight the motor stops, then tries to turn anticlockwise again then just stops in this position.

I think he said his CDI went faulty!
I had something similar with my Zeeltronic, when that went bad.

yep full charged,i talked with a japonese guy that opens cdi and servos eletronics etc, he told me might be the potenciometer from the servo, if its broken the resistor( of potenciometer) the cdi send the right voltage but the potenciometer dont "translate" and the servo rotor dont know his right possition,Sems legit. Gona check it with the multimeter , it needs to make 0.93V to 2.37V !

Update¡! The servo is faulty, the cdi is ok, tried with another servo from another bike, but what gets faulty its the potenciometer, bahhh if you get one with the same specs Just need to weld it and done!

@Calum done! Fixe the ypvs, resuming.. All the worng and default moves from the servo was cable/potenciometer problem, if you dont have one to sustitute, try clean and try all the continuity for all the cables from the servo, i had 1 bad cable{Black White} and a dirty potenciometer. Now evrething works fine.
