Haha. Come to think about it, I grounded the one I was suppose to fly last night.
You do whatever it is that you want to do to your bike first. Everybody will say something different, trust me. What do YOU want first? Do YOU want looks first? Do YOU want performance first? Pull up the nifty little search feature on the forum, and search for "mods". It will pull up a bunch of threads people have made showing what they have done to their bikes, and you might get an idea of what YOU want to do to YOUR bike.
And no, I don't have anything else better to do at 2:21am in the morning. I'm on the night rotation, so I sleep during the day.
it all deppends on what you do with your bike. if you race? then do go fast parts first. but if you do parking lot pimping then go for looks. i did both just save the money all summer, and do it all at once over the winter. thats the way we do it in michigan
