I'd be afraid to use it in the EFI bikes.

I have a friend that swears by putting Bean oil in his fuel for his four strokes.

VP leaded race gas gums up and clogs the pilot jet on our 2008 CRF450's when let sit for more than 3 days. Slight improvement in response over pump gas. 3 times more expensive. I would rather have the bikes start 1-2 kicks after sitting 3 days.
Pump gas for the 450 four strokes is my opinion.

I run pump gas with PJ1, Trick or Maxima Hi Test fuel additive and notice my bike runs better and cleaner with them. Less pinging and popping and a more consistent throttle response. Race gas feels like it does about the same.

That was the old U4. You were supposed to drain it back into the gas can.

We never had problems with C12 doing that.

I don't run race gas in my KTM 525Sx , But I do run VP C12 in my Maico 490.
The pump gas here in Houston is Crap & has too much alcohol in it to be consistent & it's a pain to keep trying to jet a Bing carb with good gas , no less the crap 91 octane we get here!

I am running U4.2 in my 09 KX450F and no problems with the EFI so far and it sounds nice and crisp.
