Hi. i have a 2001 dt 125 - first bike. i am new to bikes but have been a car mechanic for 10 years so playing with this a bit of fun as well as a learning process. the wiring on my bike has been cut about (to take basically all of the electrics off to make it into a motocross bike - by previous owner). it kicks over and starts / runs fine, however i have no operation of the power valve / servo. the power valve rotates and isnt siezed, cables are good, servo is in working order. therefore must be a wiring issue. i have a 3RM-20 cdi if that helps. and the ypvs servo is the five wire type, 4 in a connector and 1 with a bullet like connector. Looking for wiring diagrams for the bike to figure out why its not operating as it should. Any help would be much apreciated.
