I also have a K&N on the way from ebay seller ybfilters.
My mileage is 65-70 mpg, which could be frightening and a sign of running lean, though mostly I ride slow and calm. Carbs are at default settings and balanced, spark plugs ok, Shark stainless exhaust. Engine has 80000 kms on the clock. Despite the slightly low compressions I measured in the cylinders, performance is very good. Cooling fan is on every second leap year, so I do not think it is overheating.
How would you check if the engine is running lean? I can check if the spark plugs are whiteish... (mine seem ok) any other methods?
