Re: XRs on bean oil...
Hey, regarding the Pit Bull XR from Echo Park; I thought you had to "pre-heat" bean oil in a four-stroke, before it would lubricate.
That's why, back in the day, racing cars and bikes (that ran castor bean oil) used kerosene lit, "pre-heaters" that got the bean oil up to operating temp, before starting the motor.
A buddy of mine, that runs an SCTA flathead ford, commented that cold bean oil "is like sandpaper."
True?
