So again, other than someone says "it's time", or "it's due", or an expert can show you how to do it, what is the reason for doing it in the first place if there's no problem with the running of the bike? I understand that oil's lubricating ability deteriorates over time, so it needs changing. I know tires and brakes wear, so they need replacing. Valve seats wear too, but do they need adjusting or clearances inspected if the engine's running fine, or is this something the dealer says needs be done to make them a few extra bucks? If there's no problem, what happens if they are not "adjusted"?
I've had innumerable cars over the years, and some "high powered, high performance" sports cars, foreign and domestic, and don't ever recall having a valve adjustment on any of them. Other than a little higher revs, what's the difference between a bike and car as far as this goes?
