I can only report on mine. 1992 with 67,000 miles, used no oil. Valve adjustments every 26,000 miles or twice in my case. The carbs can get finikeye. Go Factory pro emulsion tubes and you only have to deal with them every 25,000 miles. An Ebay early 90 R6 electric fuel pump will save you a lot of grief. Rock solid bike, wish I had mine back.
