All 2-strokes can run a 40-1. Their is really 1 exception, some really old snowblowers and lawnmowers the main bearings were bushings so they needed a 16-1. all ball bearing, needle bearing engines can run 40-1. 50-1 to me is getting close. 40-1 ratio is a pint of oil to 5 gallons of gas.

40:1

32:1 is recomended, I run 40:1

I have ran 32:1 in my '99 YZ250. Still running great. I could probably go down to 40:1 but I am not foulling plugs and it runs really stong why chance it?

I have an 03 125 and I think I run 50:1...whatever my ratio rite says for 2.5 or 5 gallons of gas.
