Just wanted to drop a note and say thanks to everyone that posted in this thread. I've absorbed it all (or like to think I have) and now I get the chance to put it all together. I picked up a 2010 530 XC-W with a street title and will be using the downtime this winter to make a few mods to the bike. The pointers in this thread will go to very good use. Here's a pic, hope you don't mind that it's not an EXC.
