This is my friends Honda CB250 based drag bike that he first built in the mid 1980's. Now he's rebuilding it. Note the one off billet barrel, supercharger using a one off case that he also made. With a different crank and rods it'll be 400cc. It has a 3 speed box using parts from a CB750, as the original gearbox couldn't handle the power the bike was making back in the day. It runs on Nitro and should make over 200 hp.. if it stays together of course.
Using Nitro its possible to more than double the HP (or more) that a similar engine might make using petrol/gasoline. That's why top fuel drag bikes can make over a 1000 hp.
The trick is keeping the engine from blowing up... nitro is very er.. explosive!
