Lightweight BSA A65 lifters (4) for JSM radiused Norton cams (and BSAs)

For JSM radiused Norton cams as well as BSA A65 & A50. Works for JS0 JS1 JS2 cams. The outside corners are chamfered to clear the lifter tunnels for Nortons (chamfer is not necessary for BSAs). Lifters for JS3 or JS4 cams have a smaller radius – contact us to special order.
