i used to run 40:1 on my kit but noticed a thick caking of excess oil coming out of my exhaust pipe..... after changing to 50:1 the oil caking went away and i found the bike to have a little bit more power...... running less oil i believe reduces the heat created by the motor....... reason being that oil has a higher burn temp than the fuel...... ive got over 2k miles on my airsal 70cc and still running strong on 50:1
