I'm not familiar with the 80. I had a Suzuki 50cc two stroke a few months back and threw the oil injection off and just ran premix. 40:1 Klotz Benol and pump gas. I used a machine screw in the hose to the pump and put two zip ties on it. I assume it would smoke till the oil in the crankcase got used up before it quit smoking so much. Didn't have it long enough to see. Sold it a week or two later.
