Help with wires
 

Hi all, a few days ago I got a buggy/go kart on trade and I think it's a kinroad runmaster 150cc, but the wire harness was missing, so all I want to do is get spark to see if the motor will run or not.
The wires that come from the stator are: solid blue, solid green, and 3 solid yellow wires, I never seen a stator without the red/black ect wires, so any help would be great thx

:evil:
sounds like you have a 250, is it water cooled?

yes it is a water cooled 250 the number was hidden under a rear bracket.
I have it out of the buggy now as it's easier to work on.
I have another question tho, there is a metal tube that snakes around the valve cover attaches to the crank above the dip stick and wraps around to the front of the engine, all I can think of is a pressure release but not sure.

I may not be a big help as my experience is with snowmobiles. Do you have a ohm meter or better a DVOM?

I am guess that the 3 yellow wires are the alternator circuit that goes back to the regulator or rectifier to charge the battery. You can confirm that in a couple ways, the safe way is to used the ohm meter part of your meter to confirm the same reading to each of the yellow wires and nothing to ground. In other words, Y1 to Y2 should read x ohms and Y2 to Y3 same reading, Y1 to Y3 same, nothing to ground.
A wiring diagram would really help.

Also use your ohm meter to check across the blue and green wires those should read across and nothing to ground. MY other guess is these two wires are the trigger for your CDI box.

Someone must have a wiring diagram to share.

Added OK there is lots of info over in the Technical section.

OK Found this online and perhaps its here someplace, but what I posted above is just Guess so just go here and see if it helps > https://www.**********.com/tech-cent...uide-no-spark/
