I'm looking at a neglected 1984 R65 that's for sale here on the island. Lady who is friend of the owner says it last ran two years ago. Stale gas in tank, rusty frame, front brake and suspension still works, engine turns with rear wheel, seat is toast, 79,000 miles on the odometer. Your standard barn find, Puna style... I think I can get it pretty cheap. My question is this, anything R65 specific I should watch out for? I like that it has a bean can ignition, clutch carrier and handlebar master cylinder. Are R65 headers model specific? Do the carbs, wheels, transmission, rear drive etc all interchange with the 1970s Boxers?
