Frequently Asked Questions

Which cam-chain tensioner uses Honda spring 14538-425-000?

One spring B is included for the smaller B cam-chain tensioner in compatible 1979-1983 DOHC CB750, CB900 and CB1000 engines. It is not the spring for the primary or A tensioner.

How many cam-chain tensioner B springs are required?

One spring B is used in the smaller B tensioner assembly on one compatible engine, so one part services that position.

Will a new tensioner spring cure every cam-chain rattle?

No. Inspect the B tensioner body, slipper, pivot, locking mechanism and cam chain for wear or seizure and check the other cam-chain system as well. Set cam timing and tensioner operation exactly to the Honda procedure.
