You're right. My first 100 miles with the quickshifter were terrible. I was convinced it was faulty - I was of course wrong. It's amazing how little mechanical sympathy we have sometimes. I have a new car - Land Rover Discovery 4. It's a great car, but there are some small things that I can either take to the dealer immediately - the odd sound here or there, lower fuel economy than was normal on my LR3 etc... My new attitude is just ride or drive out anything minor, especially on a new bike or car. Engineering does bed down and gel with use. Anything persistent gets addressed in time, but I do think we can be rather like a hypochondriac who rushes to see the doctor at the slightest hint of a cold.
I'm not at all suggesting others overreact to faults - but I humbly admit that it's all too easy to do. Now I just relax, enjoy the 99% of things that do work. There are very few flawless things in life, so my little bit of wisdom is to tell myself to learn to love the whole - faults and all. Apologies for rambling - it's 4am here and I can't sleep. I blame Vancouver 2010 - GO CANADA in the woman's bobsleigh!!!!
