I love how "Fast and Furious" gives the impression that NO2 has no ill-effects on an engine. If my Maxi were a second bike and I had already done everything else to it, and had the money for extra 70cc kits, I'd go for it. IT would be fun as heck to have that extra surge of power. Take both bikes to a rally, make a spectacle of your self with your puch, then when it seizes ride in comfort and style on your Moby (or the chase vehicle).
