The older bikes had a problem with worn phinifler pins and piston pull-back springs weakening, but these later bikes only suffered from rotting muffler bearings.
I just hate seeing part names being used incorrectly It's kannidling pins and piston return springs. A weak piston return spring can lead to many hard-to-diagnose problems, including glowing generator warning lights at engine speeds above 13,000 RPM. A green bulb can improve the symptom, but does not fix the problem.
