QR Code Link to This Post I have a 1980 Honda 750 that is being sold as a parts bike. The Honda has been sitting with no use for several years. This bike has 7200 miles on the engine and should be still like almost new inside the engine. The cylinders have been oiled for storage but the crankcase was emptied of all oil for storage reasons. The only thing that is usable is the engine with its low mileage. It is a dual overhead cam engine with 4 valves per cylinder.
