"The bike Dragons' Breath ,has turned into a 4 year project .. everything on this machine has been either modified or self built. the bike is designed to run 150-200 ft. max runs on grass sand etc. I would like to run the Dragon on the 1/4 mile but need to learn the rules for the bike . before even thinking about that .
Engine is 13B twin rotor from a 86 Mazda RX7 NA. street ported , heavy apex seals to accommodate the turbo that should be installed on the bike before summer as well as the propane change over . This last summer it ran a highly moded 500 Holley with manual high jet adjustment . The TRAX front end is from a 82 Honda Saber running a 50 deg. rake . Vrod wheels front 90x100 and rear 100 x 120 Kenda knobby tires . Ignition is single fire direct fire built from 2 GM HEI ignition modules and 2 secondary mazda coils ( one set for each rotor ) producing enough power to make sure you never let it get you more than once . The primary clutching system is Polaris followed up by a secondary competition Team clutch running a Max1065m3 belt , from the secondary the shaft runs to the right hand side with a primary 13 tooth sprocket running chain to the rear wheel with a 47 tooth sprocket producing aprox 3.3-1 ratio to the rear wheel .
In the spring the little engine should be producing around 325 + hp with 15 or so pounds of boost @ around 8000 RPM running on 104 octane propane backed up with water meth to help keep the little dude cool . HP to weight ratio should be 1 HP for every 1.5 LBS of bike weight . To date the bike has never lost a race running in the modified class but takes on all classes and all types of bikes . Thanks the Dragon."
