I have a 250 yamaha, sitting on my work bench, with the letters/numbers on it. Can anyone tell me the year of it?
S246 058670

The reason I asked, is for a clutching issue. I have a 78 enticer 250, and its a race sled, only clutch I can run is the stock 78, splined shaft setup. I was told, a 80 or newer crankshaft would work in the race motor. Thus I could us a comet clutch. The 250 single on my bench, has a yamaha clutch on it, looks just like one that was on my 78 440, 77 340 ex, and my 79 et 340. (just the outer covers slightly different). So I was hoping it was a 30mm crank. ThanksGP292Racer said:The S246 motor was used in the 1974 GP246. I'm not sure if that model was continued in '75
