Frequently Asked Questions

What does Honda throttle-adjusting spring 53191-300-000 fit?

The spring fits the throttle-grip friction adjuster on the listed CB350F, CB360, CB500K, CB550K and CB750K handlebar controls. It is not a carburetor spring.

How many throttle-adjusting springs are included and required?

One spring is included, and one is used with the throttle-adjusting bolt on one compatible right-hand control.

What should be checked if the throttle does not snap closed?

Back off the friction adjuster and inspect the throttle tube, cables, routing and carburetor return action. Never use the adjuster to mask a binding throttle; confirm the grip snaps closed at every steering position.
