I bought an '86 Phazer last week from a coworker. (All I could afford.) Anyhow, it's a 485cc, of course. I had to put runners on it and fix one idler wheel, and finally got to go riding yesterday. Darn thing only goes 59mph. Pathetic. Is this all I should expect out of this sled or am I getting slowed that much by old bearings throughout and rusty clips on worn slides? Or is it dirty carbs? The sled runs great, starts easy every time, even cold, idles fine, so I'm doubting the carb thing. Oh, almost 6000 miles.
