|*Warning: Don't try this at home. I am not to be held responsible for any one else trying this and burning themselves, burning others or burning down something. * This is a video of my newest addition to my Baja Dirt/Doodle Bug mini bike, a dual pipe flamethrower exhaust! I now call this my Baja Fire Bug! I already swapped out the weak 2.8hp stock engine and replaced it with a 6hp Tecumseh Power Sport engine, then I added a couple makeshift air scoops out of plumbing parts, then I built a custom dual pipe exhaust for it out of more plumbing parts. Then after going to the drag races and watching the fire show the jet cars and jet trucks do, I decided I wanted to try to make a flamethrower exhaust too, to do a mini version of that, and so I did. After about a week of experimenting with different injection methods, liquids and different ignition ways, this is what I came up with. A hole drilled into the exhaust pipe, a tube with a valve going to the hole, a spray bottle filled with kerosene to inject into the tube, and two propane torches at the end of the pipe to act as pilot lights. Put all that together and you get what you see in this video. I've changed the injection system a bit since I've made this video to make bigger and constant flames even at high speed. Sometime I'll make a new video and upload that to show the mods to it and the more epic flames.
