Looking through the Clymer carb ID section I find no mention of the carbs on my 81 R80 G/S. L/H carb is 64/32/323 and the R/H carb is 64/32/324. Anyone care to chime in on this?
the Bing carburetor manual shows 64/32/323-324 as being applicable to an R80. I have the same pair on my '83 R80ST. Someone recently mentioned here that the p/n difference is due to jetting; that the carb bodies are the same, IIRC. You might get the whole story by calling Bing at 620-767-7844. Their manual is handy and not expensive, last time I checked. Far more informative than the website www.bingcarburetor.com Clymer and also Haynes are useful but less accurate than the BMW R80G/S Repair Manual. Do you need a copy?
