Rotary Shifter Go Kart build starts now! In this video we rebuild our ultra rare 1975 KC27 rotary motor found in the Hercules W2000 Motorcycle. This is a 5 speed 294cc rotary motor with close to 30 bhp. In order to get it running, we had to completely disassemble the motor and take apart the entire rotor assembly to rebuild the rotary motor. This rotary go cart uses an engine similar to the artic cat 303cc rotary snow mobile so we think that we are going to be able to buy side seals from that to get this thing running. This is going to be one cool shifter go kart build! When rebuilding this Sach's Wankel motor for this shifter kart we had to soak it in Metal Rescue for a few days as well as break out all of the embedded side seals. After the rotor was disassembled we put in some brand new OEM Sachs side seals and then installed the rotor into the housing and torqued down the casing. The rebuild seems to have gone super good! Stay tuned for the next video of this thing where we get this thing running!

In this video we drive the 60's turbo go kart for the first time with a boost gauge! This thing is powered by a turbocharged predator 212 engine. What we needed to do was make a turbo manifold for the turbo predator 212, oil system, and electrical system to make sure the turbo could run completely autonomously, that way when we hook it up to the engine, we would know that there were no issues on the turbo side of things. After we did that we ran this turbo kart under boost with 2 carburetors, made custom intake piping, and finally revved it up and tuned it so it ripped! Then, a few weeks later we decided to change things up and use a single blow-through carb design with a pressurized fuel system and a 22mm mikuni. Thanks for watching and be sure to stay tuned for this thing making some boost while driving! **Be sure to check your local laws before driving any non-registered motorized vehicle.

In this video we put a Turbo on the 60's go kart! What we needed to do was make a turbo manifold, oil system, and electrical system to make sure the turbo could run completely autonomously, that way when we hook it up to the engine, we would know that there were no issues on the turbo side of things. Before we began the install we filmed some awesome driving footage to get a preliminary test so we could compare before and after the turbo was installed.
