Same happended to me with exactly the same motorcycle... I solved the provblem by replacing the crankshaft oil seal on the rightside of the crankcase. It solved the problem immediatly!

SOURCE: what is the oil to fuel mix ratio for a 1974

I seem to remember that they were oil injection, and had a tank seperate for oil, but...32:1 will work if it's pre-mix, just jet the carburator to match that and you will be fine.
