[ijohney123]

Having trouble wireing powervalve on my dtr125 engine fitted into kx125 frame engine only kickstart servo is 5 wire servo cdi has 3 spare wires ???

[Calum]

Someone will correct me, the five wire servos, didn't I read they ran off a separate ECU? Or did I dream that.

Are you spare wires
One black yel bullet
An other 2 one brown one black both live in same connector ?

If so you need a 3 wire servo
5 wire servos also need a contrôlér but 3 don't

I need a control unit for may servo

[ijohney123]

look like tht trying to find 1 anybody know any1 stripping 1 ?

[Calum]

Can you not just get the CDI that will do both the ignition and servo.

I run a Zeeltronic on mine, which is hands down the best bang for buck in terms of performance. Gives you complete control over the YPVS operation.

[Darty]

If you have a 5 wire loom, then YPVS is controlled via the single CDI unit, you should be looking for a 3RM -?

Seperate Servo controllers were one year only on the DT125R back in 1988. 3 wire looms,
