Thanks for the Tech site, Tinsnips.......lots of helpful info there......one more thing.....my engine was likely purchased ( I'm guessing)... directly from Suzuki as there is no bike vin.# associated with it....the engine was put in a Formula 4 race car chassis by a Canadian race car builder sometime between 1985 and 1987 ......without a logbook, its difficult to nail down its precise history
Very cool! There are other sites that was just the first to come to mind. You may also find some information in the shop manuals for those years. I would think the higher the number after the hyphen the later the build. My 89 1100 engine is a little over 100,000.
Adding up the total made for each year off Wikipedia may give some minimum year for it.
