What kind of oil does a 1981 Honda cb900c take?

I have a 1982 cb900c. Check on the rear frame to see if there is an Emissions sticker. Mine is near the front of the rear tire on the driver's side of the bike. It lists several requirements for the bike, including oil type. Mine reads: SAE 10W-40 SE. The sticker is faded, but I believe mine reads 600cc oil capacity. CALL A Honda SHOP AND VERIFY THIS INFORMATION BEFORE ATTEMPTING REPAIR. Repairmanuals.com probably has original manuals for your bike. ($35-40) Overfilling oil could lead to burning oil in the cylinders, which will cause damage to the engine and cause lots of blue smoke while running.
