Default Re: The things I have learned.

Classic motocross racer mentality: "Put 110 octane race gas in it - it's a racing machine."

Then they wonder why it's lost top end over rev, low end grunt and seems to be a biatch to jet.

250F riders are probably the worst about this...

How about because the engine was designed to use 90-94 octane fuel?

Race fuel does NOT improve performance. Race fuel compliments engine performance mods that change the compression by raising it over stock. Race fuel allows the mods to work.

It's not a magic bullet that instantly adds performance, regardless of what they think.

I guess it's the same mentality as the dreaded Ford Discustang owner that puts a 5" tach on the dash and cuts off the mufflers. Louder HAS to make it better, just like race fuel HAS to make it faster.
