Okay. My turn to contribute. I have a thread on here from the summer when I made my uppers. I had a stock upper arm fold on me while riding, so I made my own. I was going to make my own +2s this time around while I'm restoring my bike, but don't feel like it, and don't have the money for longer shocks. The geometry is not that bad, really. Use heim style balljoints like I did, and you will be able to adjust the camber using the upper balljoint. WOOT! The caster is what is "tricky". Getting the measurement is not hard. Proping up the hub and knuckle is the bitch. I measured from the front of my foot pegs to the center of the upper balljoints before I tore the front end apart. I came up with 25" both sides. Just need to keep the the hub/knuckle propped up to keep the balljoint center right there and you're pretty much golden. PUT THE NEW BALL JOINT IN THE KNUCKLE WHEN YOU DO IT!!!
Flipped rims work great, and give you pretty much the same thing as +2 arms. I run WORKS AT Steelers up front, and the bike feels great. I'm selling the uppers W/OUT balljoints for $125 shipped.
