I'd have no qualms about fueling up, throwing a few 64oz. bottles of Maxima "927" Racing Castor under the sidecar nose bubble, and heading for Portland, OR on the I-5 taking it easy in the #4 lane. I often ride it on the I-5 from Chula Vista to VespaMotorsport in San Diego, no problem. I've only been stopped once by the CHP because the officer was curious. During the Hell's Loop T.T. I ride it 63 miles from Barstow to Baker, towards Las Vegas, on the I-215 Freeway!
