Hi, This is the same frame I've had for a while with a new 125CC 4 stroke, 3 speed, automatic clutch. I added two more bearings to each hub and the jackshaft. Each has 4 bearings now. The gas tank underneath is new with a pulse fuel pump. I made it from oval exhaust tubing and it holds about 1/2 gallons. The tank on top the engine holds the electrical components. The seat is a new bobber mounted to the Micargi seat springs.

CH: The pedal chain just runs under two idlers from a chinese engine kit. One holds the top of the chain and one the bottom.

Thanks. The fuel is moved by the pump attached to the side of the tank. It has a hose that is connected to the intake manifold. The pulses created by the piston in side the engine moves a diaphragm inside the pump which pumps the fuel to the carburetor. They are common on snowmobiles, ultralight airplanes, jetskis etc.

Thanks! Fulltimer: between 55-60mph depend on the wind. Strong headwind really slows it down.

wrx2bike: Thanks! I bought the engine on ebay. Just punch in 125CC engine.

I told ya these guys would love that bike..It is tastefully awesome.
Good job.. Those engines will always remind me of the old Honda mini-trails from back in the early 70's, only yours is a whole lot bigger.
