I'm not sure if I'd get more responses here or in road warriors, but here goes. I'm looking to buy a K75 with 59,000 miles, pretty clean, good looking bike, good price, but the spline lube history is unknown. Guy who has it now has ridden it for 30,000-ish miles without having done it, the owner before him SAID that he did, but there is no documentation, so who knows. I rode it, and it shifted like butter, both up and down through the gears. I really like the bike, and want to buy it, but spline lube doubts have got me reconsidering. Any thoughts?
