SP1, great. SP2, greater. SP2 with 3100 mi., Greatest! IMO that's a - great -find. SP2's got some more tweaking, like bigger throttle bodies, better injectors, improved suspension, are a few. That low milage on a 9 year old bike is rare. Negotiable, probably means you can get it for 5400 or 5500, maybe less. Depends on how "motivated" he is when you show up with cash. And it's got decent exhaust, dubbl bubble windscreen, maybe a couple other goodies? Look for a pcIIIusb, or pcIIIr, or a pcII. I'm sure you know about Power Commanders, but those are the ones you'll find on the RC's. Do all those things madbuyer said, and if it checks out, you got a real bike there. Look at those tires real close too for age and weather checking, they might be original. 190/50-17 and 120/70-17 are stock sizes. If you see 190/55-17 that's cool too.
Are you anywhere near Bakersfield?
