Sorry to bust you theory paul but all the mx's had that STUpid switch system regardless of the cdi/mag combo, confuses my MOT man every year.
The only DT with on,off AND park as far as i can see is the 125E with the leccy start, ( a twinshock to boot). The plot thickens.
That switch has red, brown, blue, and green coming from it. Yes?
I'm guessing that switch may have come from the LC? Then it would have Red, black,black/white, brown, blue and blue and red?
