This is a motorized bicycle forum not a motocross forum but let me see if I can help you.
You have no spark try a new spark plug gaped at the proper gap for your engine.
Check your wiring connections for broken or bare spots. You might have a bad coil or cdi so if you can get a shop manual for your bike or find a forum that you can address your problems to for more help.
If all else fails find a bike shop or mechanic to help you get it repaired. Hope you find your problem.
