I love the fact that I could swap my pistons in the time it takes some folks to change their oil.
The swapability of parts on these bikes is great too. It's easy to find parts since they went on so many bikes. I'm going to pick up a good used gearbox and heads and stick them in drawer somewhere. If I ever have problems I won't get my parts fixed. I'll just swap them out. Takes less time and it's cheaper.
