At least part of it's working right.Keep us updated at to what you find. Plus you can use a simple meter to check continuity on the ignition switch and on/off switch left control switch wiring.

I will defiantly keep yall posted on what I find that completely fixes it because I know I've been searching for months on how to fix the problem but never could find anything, glad I'm in the right direction now but defiantly glad to get to ride it for the first time. Thank you for all the help, Ida thrown it away soon if I wouldn't of found ya haha thanks again

i thought it was the pulsar coil gap but i do have it set to 0.025 and ive tryed several diffrent positions
my stator was fried.. the wires were all exposed and basiclly black , is it possible my cdi is done aswell?.. im after any suggestions thanks for reading

its your cps crank positioning sensor.. 100 bucks.

We put it on and it's still doing the same thing. Not sure what to do next. We replaced the carb, spark plug, fuel pump, fuel filter, and fuel lines. Still doing the same. It will also backfire through the carb sometimes

i redid the ignition, plugs, wires, everything... turns out it was the CPS crank positioning sensor... 100 bucks.. you can put a new one in under 5 mins.
