Pig Pilots, At long last I received permission from the wife to spend some bucks upgrading Notorious P.I.G.'s flaccid suspension. I picked up a 1995 CR500 roller for cheap and made a tentitive plan: 1) Swap the CR500 forks and shock onto the XR600 2) Swap the XR600 forks and shock onto the CR500 roller 3) Buy a tired XR200, yank the motor, freshen it up, and install it in the CR500 roller to make The Ultra Wife Bike (to replace her current ride, an '02 XR200 with upgraded 1980s suspension). Aside from any real or imagined performance advantages, I want to do it "just because." It's been 10 years since I've really "worked" on bikes (one of the benefits of XR ownership?) and I'd like to get back to getting my hands dirty again. This morning I took apart the back of the CR500 and pulled the shock. I learned: 1) Removeable subframes are REALLY nice. I wish the 600 had one. 2) In no way shape or form will a CR500 shock EVER fit an XR600. It's about 3 inches longer, although the mount holes sort of line up. A CR500 shock install would need the shock flipped 180 degrees to clear the intake boot and that messes up the top eye alignment. 3) The steering stems are both 7 1/4 inches which gives me hope that the bearings and other bits will be somewhat compatible. Your bits of wisdom, insite, sarcasm, and random quips are more than welcome; I don't profess to know much (okay, anything) about what I'm doing here. "O"
