About This Product
MCS standard steel breather valve for 1936 to 1947 Big Twin models. This is an OEM-style replacement for 25300-36 and 970810. Manufactured to the original specifications. It times the breathing cycle correctly on Knuckleheads and early Flatheads. A worn valve leaks oil and ruins scavenging. Fit a fresh one during every bottom-end rebuild to keep the motor dry and prevent leaks.
Manufacturer part number: 970810.
Fitment
36-47 Big Twin
