Ok, I figured I'd post this up for those in the near future looking to get their XJ roadworthy....for starters, this is where I began: http://www.xjbikes.com/forums/threads/new-build-xj550-seca.85892/ , physically, the bike looks no different (well that's not completely true...it has new tires and a SS brake line) today than it did when I took delivery. From start to finish I: 1. Changed oil and filter 2. Clearanced the valves 3. added new valve cover gasket and pressure washers 4. completely rebuilt carbs (total disassembly/cleaning and all new parts) 5. completely rebuilt front brake hydraulics with all new parts and pads 6. Replaced rear brake shoes 7. New air filter 8. And finally, new tires. Total cost for parts alone....just north of $900. Now there are many things that still should/could be replaced like wheel bearings, headset, front springs and seals, rear shocks, swingarm bearings....and on and on... but my point is $900 should be considered the minimum cost to get your "barn find" bike back on the road. Keep in mind the old racers adage "You can go fast, You can go safe, You can go cheap......but you can only pick two!"
