I am finishing up my 1978 XS750 and will be posting it by the end of winter.. i got the bike for $100 and rode it home!! Between eBay and bikebandit.com it was not difficult to find parts at all. Things to look out for are the self-destructing 2nd gear (i got a lightly used transmission off eBay for 30 bucks), electrical problems (i didnt experience any but they are a possibility because of the extensive electronics: self canceling signals, bulb check system, reserve lighting for headlight: pretty cool stuff for '78), leaky fuel petcocks (they are vacume operated). The XS750 and XS850 are great cruising/touring bikes in their stock form because of the smooth tripple engine, shaft drive, and twin rotors up front, but with a decent amount work and money i was able to cafe mine.
