About This Product
MCS primary chain adjuster kit replaces OEM part number 39967-77A. It fits 1977 to 1985 XL Sportster models. The kit suits older Ironhead and early Evolution engines. It is sold as a kit. A worn or notched adjuster ruins primary drive feel and adds mechanical noise from the primary case. Fitting this kit restores correct chain tension. That stops premature wear on the drivetrain and improves shifting.
Manufacturer part number: 997555.
