Tune with the the main jet and air screw, The plug will tell you if the mixture is correct. a nice medium brown is what you are after. The mixture will need altering depending on what you are doing with the bike. If you are racing it then you might need to go up to 20/1. Trial riding then 32-1 is fine. That's using a mineral based oil, the old dt before my time paulus but i wouldn’t run any 2 stroke i’ve ever had on 20-1 like you say in thread it will foul up Edited May 23, 2023 by mC HULL 1 Quote Link to post Share on other sites
