Why I won't run pump gas my buddy pulled this out of his 150 today .. That is detonation... Caused by lower octane crappy pump gas.
That's like top end number 38423894748 for Eric..

Well, lol you are not wrong about that .. He ha had nothing but race fuel in that since he rebuilt it ( again ). He ran pump gas 2 times and boom... Gone. If you can't see detonation on that piston you need your eyes checked.. Hot spot in the middle, and sandpaper like pitting on the edges... Keep running your pump gas.. I'll run VP, to each their own. Eric said he's buying it by the 55 drum now lol
rocket surgery eh
Bill has some sort of hatred for VP.. Maybe the CEO Beat him up as a kid or something..
Says the guy that can't type the words "pump gas" without using a degrading adjective before it Did you get beat up at Speedway once upon a time?
Run T4..... People will tell you your wasting your money, your not.. Those are just the ones afraid to do a little research on what they are feeding their $6,000+ investment.
So if your worried about protecting your $6,000 investment by running race gas, why dont you run race gas in your car? Cars cost more than a bike.......
Too much ethanol will rob power and cause a lean issue in non fuel injected bikes because the jetting needs to be richer. Fuel injected bikes automatically compensate.
Unless it has an exhaust O2 sensor, it won't compensate for anything except air density based on whatever the heck the manufacturer decided would be the right fuel. As far as I know all the F.I. mxers are like our YZ250F and run open loop - no exhaust O2 sensor.The current o.e. produced fuel injected MX bike will not automatically compensate for a rich or lean condition that is not within the parameters of the given variables already stored in the ECU. (fuel/ignition maps) It deff. will not compensate for the amount of ethanol in the fuel.
For the purpose of this conversation the biggest problem with ethanol in our fuel is it produces less energy than an equal volume fuel/gasoline without ethanol.

With an O2 sensor they could compensate for a lot more but would require a detonation sensor to compensate for low
octane fuel.
