If you simply dumped the gasoline and poured nitro in your tank, the bike wouldn't even run, much less make more power. Nitro actually has less btu content than gasoline. The reason an engine can be made to produce more power with nitro versus gasoline is because, for a given volume of fuel/air mix, the nitro mixture will contain a much higher percentage of fuel than the gas/air mix. Gasoline burns best at a ratio range of 12-14:1 fuel-to-air, while nitro burns best at a ratio range of I believe around 6:1 fuel-to-air, or roughly twice the fuel with half the air. Obviously, you ain't gonna get the two different fuels to work with even remotely close to the same jetting, maybe not even the same carb. I don't really know about using the same carb because I've never ran nitro in anything that I have owned, due to the very high price tag. I don't think I want to pay $100 a gallon for fuel for my bike. On a side note, improving your fitness and riding skills, and setting up your suspension and ergos for you, will do far more to increase your speed than any magic fuel potion will ever do. Doubling the horsepower of your bike will do nothing to make you faster if you aren't skilled enough to put that power to use, it may actually even make you slower. [/QUOTE]
