Hey Jeff here with recent purchase of these two CT70's, yellow dated 9/71 and blue 6/72. So are they a 1971 and 1972 or 1972 and 1973? Neither one is running currently. I rebuild both carbs and upgraded to CDI ignition. Blue one needs new harness since a mouse at the old one. Both bikes are 95% complete, blue one is missing tail light and they are both missing the engine guards. We will be camping off grid and deep into Canada/Alaska later this year once the border opens. We also have 11 grandkids who will be riding. I don't plan on re-painting etc. I want them running 100% and look forward to learning from you guys.
