Thanks for writing this up. It's a Wealth of knowledge. I know you just recently purchased the bike and probably don't know much on the history but I would like to know the brand,,weight & change frequency of the engine oil that was used by the previous owner.
Everybody has a favorite oil. And a lot of people have low mileage bikes with with pre-mature problems of bearings & followers, but few match the problems with their oils.
I agree completely. With oil change mileage intervals being so long, and if a good syn oil is not used and then not changed for a couple of years based on mileage oil breakdown is inevitable. So low mileage bike should have oil changed every year if not ridden often enough. That why the advice on a oil change on a new low mileage used bike is recommended right after purchase.
