Hi, this is my first post so please excuse any faux pas and give me a nudge in the direction of correct behaviour. I'm riding what i think is a 1996 DT 125r with an '04 engine. there is a servo motor attached but the connector on the end of the wires coming out of it isnt actually connected to anything and i cand see anywhere it may of come loose from. when i took the cover off the power valve pulley cover to adjust the cables there was no movement either when i turned on the ignition or when i started it and reved. this didnt change despite me tinkering for a bit. Perhaps I should add that this is my first bike and though im not stupid all i have to help me is a haynes manual and a toolkit so any help will be very gratefully received. Marcus
