I have an 02 CRF and was thinking of running race gas, whether it be 50/50 or straight. I've never run race gas in any of the bikes that I've owned, I was told about it through my local shop. I guess my qeustion is, is there a huge advantage to doing this? I run stock jetting right now with a White Brothers R4 slip on. Would I need to change jetting? Right now I run Chevron 92 octane. Any words of wisdom would be great.
