Does anyone have a spare flywheel for an 86 KX500 ? What other years or cc size use the same part ? Can I swap out different year and or makes stator and flywheels to get a matching set if I can't find an 86 flywheel ? What exactly goes wrong with a flywheel ? It seems bulletproof . Mechanic says he needs another tho . Thanx in advance for your wisdom.. Dave
