On the '78 CT90: Changed the oil, put new bulbs in the speedo, replaced the headlight, did the RS rectifier upgrade, put in an enclosed case battery, fixed the horn

On the '81 CT110: Changed the oil, cleaned the carb, put new bulbs in the speedo

Rode both of them around our cabin all weekend, what a blast! Many thanks to DrATV for the boat load of parts I have needed as well as this awesome forum for showing me how to fix my own stuff.
