I used some MR8 at the last race. Frontierdon. Awesome. F'in unbelievable. I am now a believer. But I found out on the VP page that MR8 is for 125 and 250 2 smokes. Octane 107, leaded, oxygenated, yellow in color. I was running a 4 stroke 500 single.

The VP web page says this shit can be shipped UPS!!

I guess if it works it works. What isn't on their web page is

1. how long it lasts and
2. it says on the can not to leave in the carb/tank. But for how long?
3. I am going for a dyno test on Friday at MM. We'll see. All I know is I kept up with TK's 650 duc. (but he did say there was a "shimmy" in the steering)

I just need to get my post count up.

We're pretty lucky here to have 110 octane Cam2 at the local gas station. I had been running it mixed with 93 in the Hondas. The C12 felt like it made a difference, higher rpms according to the tach. An actual dyno comparison would be really interesting.

Had been running straight Cam2 in the sidecar but starting mixing it down with 93 on the advice of an old racer. Those heads like some extra heat to help with combustion if not running dual plugs
