My Aprilia RS125 has failed its MOT as the front light direction was not changed when it was brought into the UK. How do I change it?

they are a bit like that anyway mate because of the useless dellorto carb they use but what will make t worse is if the powervalve is either set fully open or if it is stuck open,check if it has a servo/actuator or if it just has a bolted in powervalve blade.the valve is behind the radiator on the top front of the barrel just above the exhaust manifold where it bolts to the barrel.

I have just brought an aprilla mx are the lights supposed to come on when I turn on the ignition I cant see an on/off switch.

the sensor is located on top of the carb, there are no adjustments for this the only way to remove warning lights is to replace it there not to expensive around

20 05 Aprilia RS 125 ive just rebuilt engine , started up ran fine , put fuel tnk ack on now wont stat at all dont even spark i heard bleaping noise from imobilizer help please thank you colin

yes

front axle nut/bolt is 80nm
front axle pinch bolt 10nm

try the fuse. although i would think if its a fuse then the beam light would not work either, but check anyway, or it could be a bad ground / earth on the lighting circuit
