Since I don't have a dyno I can't throw HP figures out, but I can tell you I had to up my main jet by ten numbers, and richen the needle one step...this stuff is oxygenated and not AMA legal...the smell will kill anyone behind you, but its well worth the money(over $7 a gallon)
I'm going to see how it does on my buddies piped raptor
It made my xr50r a bike length faster in every gear...

 

A guy I know had some of that fuel at the track last Sunday. He used to race street bikes and gets it at a good price from VP. He said it's 92.3 octane so you can run it a stock compression motor. Another buddy of mine was running it in his YZ 426 Lonestar quad. He said he didn't like it and said it wasn't worth $7.00 a gallon. I don't think he re-jetted for the fuel and since he did crappy in both of his moto's, I suppose he had to blame it on something. I will probably be purchasing some of this fuel from this guy and will try it out in two weeks at the track in my Raptor. Let me know what you had to do to your buddy's bike to get it dialed in and let me know how it runs.
