i tallied up my receipts around the time i got my 550 put back together and on the road, and it was at around $1500, including the purchase of bike itself ($200). powdercoat, new bearings everywhere, new seals everwhere, SS screws for the engine, homemade fiberglass seat and exhaust silencer, new tires, new 16" rear rim and SS spoke kit, dyna-s, etc. since then, i've added SS brake lines ($103 for a dual disk setup), boge progressive shocks ($50), and a few extras, but can't have possibly passed $1800.
good thing elbow grease is free, huh? sheesh.
