So, I started thinking about maybe sourcing a Sachs KM48 160cc 2-stroke rotary and doing a build around it using my Adventures 700c, since it's already there, and a rotary seems like it would fit in the frame better than a 5hp Briggs flathead would, and would look a bit better than a 2-stroke kit piston engine as well, plus it suits the look of the frame better. As for the transmission, a CVTech CVT would be used, and the pedal and stock crank and gearbox would be replaced by a jackshaft and a rear sprocket aimed at high speeds. Stocking up on apex and rotor seals would also be required, as well as rebuilding the motor whenever the apex seals fail, which the 13b and 20b guys also have to deal with in the 4-wheel world, and everything that would make it safe and legal on the highway would be taken care of as well.
So, which would be a better fit in the Adventures frame, a 160cc rotary, or a piston of the same displacement?
