What fuel octane and mix ratio for the YZ250X? I am rocking a 22 YZ250X and I run 1 gallon turbo blue 118 octane to 4 gallons 90 non ethanol to make 5 gallons she is crispy at 32:1 yamalube premix.
@@johnmclaughlin4802 My modifications (WR450F): only slip-on muffler Akrapovič or YZ450F exhaust and good choice ECU map (really important). WR450F has great stability, strong and smooth engine performance. Amazing KAYABA chassis.
