Have new to me K75, 12,600K. I took it for a shake down ride, about 100 miles. Found the mileage was about 32 mpg. Started to change fluids, and the oil was over filled, maybe 1/2 a guart. Would this be a cause of poor mileage??
Have fork seal leaking, and there were no bolts in the top triple clamps!! :yow, may be cause of slight weave in grooved pavement. But biased tires can also do this. To used to radial tires. Phil
