I have a 14 yzf250 with a get ecu that is programmed for T4
I don’t ride much at all and I am wondering if my bike would be fine with Pump 91 non ethanol
I also have the stock ecu I could put in
My bikes mods are PC head , PC piston, PC Cams , PC valve springs, Delwest Ti Valves , Ti6 Exhaust
Would it be fine with 91 non ethanol? I am not fast at all and I don’t rev limiter it
ask your mechanic, they'd know best for your specific setup.
Depending on your altitude and the compression ratio of your piston you may be fine. Usually CR of 13.5 requires at least 97. You could also cut the T4 with 91 pump and see if it pings.
