I want to use my bike every day, but don't have the opportunities at present. For me, use it 'til it breaks or wears out then replace/fix it. I keep the bike in the best condition I can, but occasionally need to 'modify' or replace with something a bit non-standard. Case in point is when I lost about six engine mounting stud nuts plus a stud itself. As an emergency, and so I could keep riding, a length of metric, threaded bar and nylocs have done the job. I know that one forum member berated me for not using the right parts, but I want to ride not sit waiting for the post to arrive just so I can say the bike is 100% original when I go out. This summer, I'm putting an AM26 on the back so I can lean a bit into corners without worrying about whether it's going to hang on, especially in the wet. When I'm old and unable to ride and the bike's in the living room and I'm admiring it with a whisky and reflecting on times gone by, then I'll be looking at all the bangs and scrapes remembering the adventures we've had.
