plug wire??
ground lug making good contact??

 

[scott347]

New wire with coil and checked the ground is tight

 

[ellandoh]

kill switch??

my last hope for an easy fix, more will require a multimeter :yell:

probably stupid to even mention but last, last hope would be the plug

 

[scott347]

Check kill switch and even held a screwdriver in the plug cap against the head and nothing thanks for your ideas

Check the timing? pull the ground off the coil and take a wire brush to the contact point on the frame. Ive spent hours troubleshooting spark issues and it was a dirty contact. What kind of plug are you using?

As ellandoh mentioned, your gonna need a multimeter to trace the fault.
Firstly, spin the engine over & check you have voltage coming from the stator.

I got it guys thanks it was a wire for the stator got cut when I put it on got it running and the power valve isn't working so now I have more problems.

What makes you think the valve isn,t working?

I took the plug on the left side of the enging out and with the bike running there a mark that's stright up the book says when u rev it up the mark should turn 90 degrees and it doesn't move. Plus when riding it it's slugush and no power band
