By the same token there will be any number of knobs walk into a bike shop in one week. People demanding tyre changes at the drop of a hat, wanting to borrow tools, general whinging about the price of parts, having to order in parts etc etc etc.
A good one a mate told me was a fellow brought a GSX-R 1000 in saying it had a 'death wobble' at 220k's, he left it there for a week and when the fulla came back he asked "did you fix it","yeah just stick to 219 in future"
