The products list 14 front teeth and 43 rear teeth for 630 chain. The supplier asks buyers to count existing teeth and check chain length before ordering. Confirm those details rather than assuming the motorcycle retains its original setup.
The stud set contains four 12 × 54 studs replacing 90128-341-000 and four nuts replacing 94030-12000. The separately listed tongued lock washers come in a two-pack replacing 94108-17000. Match the required hardware to the fitted flange.
Both selected sprockets specify 630 chain. Confirm the fitted chain type, tooth counts and required chain length before ordering for a motorcycle that may have been converted.
These selected sprockets specifically list the 1977–78 F: front reference 23801-410-000 and rear 41201-410-000. Match the fitted assembly rather than extending the application to an earlier F from the model name alone.
The genuine Honda primary-chain tensioner is for the engine’s primary chain, explicitly distinct from the cam chain. It replaces 13620-300-010 / 030 / 505 and is not a rear drive-chain adjuster.
