hey bud.
If the plugs are good, would be sure the clutch switch and kickstand switch are working properly or looped out correctly if you are not using them.
I would test your coils if the above is good. Check restance across the coils + and - posts. Should be somewhere around 15k ohms. Also check resistance from the + post and the plug boot. should not be more then .5 ohms. If it is above either of those, the coils are bad.
I would also be sure the ignition pickup is working. There's also a diode, small square plug near the back of the bike in the harness. If tha goes bad or is missing it won't fire. Hope that helps.
