Has anyone tried race gas concentrate? Just wondering if it's worth using.
Octane boosters are a joke but this stuff is supposed to be way better.

There's a few other brands out there incuding one by VP. It's hard to get race gas around here and I am looking for a safe non-ethanol alternative for my RM250 and KX500.
I can buy non-ethanol 90 octane locally.
