06 suzuki s50 turns over no spark - Suzuki Motorcycles

Hi... my 2006 suzuki boulevard c50 vl800 no spark

First check spatk plug is actually sparking by removing it from engine and reconnecting plug cap, then place metal part of plug against engine, with ignition on crank it over, if no spark try replacing plug first, if that fails check plug cap, lead, ignition coil and all the way back to the cdi unit
