1984 Honda CB650SC Nighthawk · Engine Cover Bolts Buying guide
The Nighthawk set listed for 1983–1985 supplies 49 bolts and one Allen key. It describes hardware for the visible engine covers. Available products depend on your selected country.
The listing describes bolts for the visible engine covers. It does not claim to replace every engine fastener or include a bolt-location chart. Match the actual covers and existing hardware rather than treating the package total as a complete engine inventory.
The package identifies 49 stainless bolts and one Allen key. It does not identify cover gaskets, oil seals or replacement covers as supplied. If your job needs those parts too, verify their own applications and contents before combining them in an order.
Keep known original bolts laid out by cover position and replace them one at a time, comparing lengths before starting each replacement by hand. This listing does not provide a bolt-location chart or individual lengths. Use workshop information for the fitted engine and covers rather than copying an uncertain mixture of old fasteners.
No universal thread treatment or torque is specified for this kit. Follow the Honda procedure for washers, thread treatment and torque at the relevant cover positions. The product guidance warns that overtightening can strip an aluminum case or distort a cover; the supplied Allen key is not a tightening specification.
Start with the exact application. Other CB650 variants have separate listings, and package totals include tools. A piece count alone cannot establish bolt dimensions, cover coverage or interchange between those applications.
