I like them both.I think the 92 nighthawk has hydraulic valves,no shims.That is a big plus to me.It has 38,000 miles, the 80 750 f has only 9,000.Both same price.
I have 79 650 and 2 80 650's.long way from being able to get them running. Am looking to buy either 80 750f or 81 750 custom.i heard different opinions on sohc and dohc.the sohc was great.why a dohc? Was because of suzuki gs or kz 1000?
