Frequently Asked Questions

How many turn signals does one pinch-bolt set mount?

The set includes two chrome bolts, two hex nuts and four flat washers, enough to clamp two turn signals. Two sets are required to service all four signals on one compatible motorcycle.

Will these pinch bolts replace the original 25mm bolts?

The replacement bolts interchange with the 25mm originals on the listed 1969-1974 CB750K, 1971-1973 CB500K and 1974 CB550K signal clamps. Confirm the stock stem and clamp arrangement on modified motorcycles.

How should turn-signal pinch bolts be tightened?

Align the signal stems and wiring before tightening, make sure the washers seat flat and tighten the clamp evenly. Do not crush the hollow stem or pinch the wires inside it.
