CRF's Only Forums

As the title explains, I am looking for a crf50 for our little girl. I have come across the following local ad and have a question. It states in the ad that he ran 50% race gas. Is this ok? I have heard of running race gas in 2 strokes, but not 4 bangers. Should I be concerned about this? Does it matter what kind of race gas he means? What sort of questions regarding the use of race gas should I ask this guy?

thanks,
snake

Don't worry about it.

He's trying to make the point that he ran "super clean" fuel so the carb is spotless.
