Hey! That’s one of my customers bikes!^^
E85 is great, and I use it a lot. However I never suggest doing it on anything that doesn’t have an ecu that can compensate for different ethanol levels. That is unless you’re running drum e85. Pump e85 just has too much variance in ethanol content. I usually see 63-75% here, and every once and awhile a random 80ish here and there.
You do need a big fuel system though. You can knock 30-40% off of what a fuel system is rated for on gasoline.
