Thug, surprisingly little real "work" was involved in putting the 650 right. My younger brother (bless his heart!) found it in a small engine repair shop in northern Illinois under a tarp with a mechanic's lien on the title. He payed off the owner and the mechanic for $1,300 cash, the same price I paid for my identical '72 when I bought it new from the dealer. Bike had 3,500 original miles on it. It had only one non-standard part on it, a 2 tooth smaller front sprocket which was quickly changed out. I spent about $500 on parts from Mike's XS, a guy in Florida who publishes a 70 page full color catalog of parts for the XS 650s. I bought every gasket, filter and spare part I could find, and put OEM (but not NOS) coils, wires, points, condensers, new tires etc. on to replace the 33 year old originals. That and a few by the road carb field strips, and it runs just fine. I now have a box of extra replacements parts that will last the lifetime of the bike, in case Mike ever retires. Still a few things to do, but by in large it was easy to get it back into riding shape as a stocker.
