Hello, I have a 1997 Yamaha RT180 2 stroke. I recently repaired it by doing cylinder rebuild with an overbore. I had to mix the fuel, because the (I think its called a jet, not too sure, its that cylinder disc that turns when you throttle and lets oil through) broke previously. It has been replaced, and I need help to figure out whether I should mix my fuel or not. I tried a 40:1 ratio, and it was putting out trails of white/blue smoke. Like a LOT. I tried 60:1, same thing. I dont really know what is going on. Should I try 70:1? Or should I just put gasoline in the tank without oil? Im new to riding so excuse my lack of knowledge.
