I am the seller.
I pulled the carbs out of the good one last night and have them in a box ready to go to Steve for his rebuild. Woke up this morning with the idea of trying to sell the good bike (and the parts bike) in as-is condition for a little while.
(I would probably not ride the bike much after I put some money into it to get it humming and re-shoed.)
Am offering them for sale in current condition at a great price and letting the next owner decide what to do about the carbs and tires.
