April 25, 201214 yr The wiring for my 2007 SY 250 headlight was missing so after studying a wiring diagram for a couple of models I connected it up and at idle it is nice and bright but as I rev the motor the light fades?? Thats supposed to be the other way round, rev and it gets brighter. Its clearly a connection problem but Im not sure where. Any ideas?? Tx TCD
