As I am very new to the sport, and also very new to working on bikes or performing modifications of any type, I am wondering what order I should do the modifications, and also, while all you TT experts are responding, would like to know which of the mods are a bit more difficult to do than the others. I know drilling the hole's at the muffler's end is likely the easiest, but rejetting is a bit intemidating as I really don't want to screw up a perfectly running bike. If i do some mods to the exhaust does that force my hand in having to do a rejet. I look forward to digging into these things, just apprehensive to get into it. newbie jokes accepted and expected. thanks in advance.
