Compatible Crankshafts
« on: October 11, 2010, 06:50:15 PM »
anyone here know if you can replace a 82 CB650 crankshaft with a  82 650 nighthawk crank?
and if so, what other changes are required/recommended?

I think the only difference is the Nighthawk engine is painted black. Don't believe the crankshaft would care.

83 Nighthawk is DOHC, 82 is SOHC so it should be same as Standart or Custom 650.
