I have a 83 klt 200 duckster project I've been plugging away on for a while now. Went to test the wiring system out today and no spark. Any leads on where to start looking/testing. Also need a lead on a air box and lid, looks like a one year deal for that. I've been on eBay with no luck. Thanks Brent

 

The only way to effectively troubleshoot a "no spark" issue is by using the manual. That's an old machine but....this place may have a manual for it.
