Just draining to change the oil = 2.6 quarts
How much engine oil does a 1982 Honda Nighthawk 650 take? 3.4 quarts
3.1 quarts
"Honda service manual says...2.4 quarts when draining...and 3 when completely disassembling engine."!
An 82' nighthawk 450 takes 2.6 quarts of of sae 10w-40 SE or SF grade oil... Although I've heard from friends who ride say you should get motorcycle oil or Honda specified oil. The nighthawks have a "wet" clutch system and regular car oil will burn out your clutch.. that's from a ATV technician..
12.75 .oz #10 fork oil 6psi pressure
left 15.7 right 15.2, 0-10 psi
Depends on condition an mileage plus what model Honda none of which you listed.
1.7 quarts
If everything is functioning properly, nothing is missing and the cosmetics are decent, then the bike should be worth around $1,100.
