Here's my '70 Honda CM70! I'm (finally -it's taken two years!) done with the restoration and just listed it on Ebay.
Even though I've owned quite a few Super Cubs, the '70 and '71 models have always had a special appeal to me - a significant update to the original design (note the "real" turn signals and larger headlamp), but still retaining the bolt-on fuel tank and ignition key in the side cover. This version even has a "night light" that you turn on by pushing the horn button (when the ignition is off), which helps you in the dark to get the key in the switch: no other model years have that! The highlights of this project are the rebuild of the original motor, which increased the displacement from 70cc up to 90cc, and upped the transmission from a 3-speed to 4-speed. I also added larger tires (2.75 rear; 2.50 front), and a headlight with a replaceable bulb. Everything works, runs great.
In accordance with my agreement with the better half, I have to sell this bike before moving on to my next restoration, which is a '65 CA100 (50cc).
