About This Product
When your starter solenoid starts sticking, a fresh return spring is often the simple fix you need. This MCS return spring is a direct replacement for the factory component, ensuring your starter motor solenoid retracts properly after every engagement. It is built to original specifications for a reliable fit and long-lasting tension. This part fits 1989 to 1990 Big Twin models as well as 1981 to 1990 XL Sportster models. It replaces OEM part number 31557-81. Sold as a pack of ten, this is a handy item for any workshop or mechanic who frequently services older Harley-Davidson starting systems and wants to keep essential small parts on hand.
Manufacturer part number: 930101.
