Welcome to the forums Mick
A couple of members have changed the front sprocket to alter the gearing so I'm sure they will be along soon enough. As for the mirrors, you're right, the stock stubby ones are pretty useless. I think one of two have swapped the mirrors over on each side before, but my preference is to get the FZS 1000 (thou Gen1) mirrors as a replacement. They fit without any modification and have a longer stem so you have a better chance of not just getting a lovely view of your elbows / shoulders
