hi, i am 15 and have been rebuilding my kmx 125 for nearly a year now and spent towards £1000 :( . i need some information on completing the wiring. i have a wiring harness, a coil, pickup, magneto and i know that i need a CDI. is there anything else i need to get a spark and is it as simple as plug it in and were off or do i need to change anything.
thank you for your help.

for a spark all you need is the high voltage magneto winding (not the charging windings), the pickup, the CDI and coil (HT lead and plug obviousley)

a 12v source is not needed power for the CDI and coil comes from the high voltage magneto windings (300 to 400v ac (ish))

hope this helps... now i need help with my kmx rebuild...

where do the 3 carb overflow pipes, tank breather pipe, gearbox crankcase breather pipe, oil tank breather pipe and coolant tank overflow pipe go?

thanks

if im correct in thinking.... the one at the bottom of the tank runs straight up and through the tank to the top near the cap. i think that it will jus need a short piece on it and perhaps tie it to the carb overflows. . . have a look in the tank and just confirm that.

dont speak to my dad its my uncle really who has got me into bikes. . if you were intrested in selling i would be intrested as i want a trials as a project and i plan to buy one after kmx anyway. my uncle has a 300cc gas gas raga (like the one in the pic but last years) and my cousin has the gas gas txt pro 125cc. i like them both but the front comes up too easy on the 300 and it aches your arms after a while. any more info on that montessa if you would be intrested.
thanks
