Just got my Dad's old ride up and going after a 6 year hiatus. Cost about 1,200 in new tires, brakes replacement seat and hardware and replacement of a frozen fuel pump (thanks beemerboneyard.com). Has about 47,000 miles should be good for about another 150k before anything major need replacement. Amazing.. after replacing all the neccesary fluids, spark plugs and other running gear the sucker just fired right up. Bike is a 91 K75, 643 Marrakesch Red running smooth as new.
