Started work on my Post Classic pre 72 Kawasaki F81M 250cc single racer.
Kawasaki rotary valve cases, Suzuki crank and air cooled cylinder, Honda CR250 rod kit. Enormous case volume and with a modern pipe and some Methanol in the mix to keep the engine temperatures down I am looking for 45 rear wheel hp @ 9,500 rpm. Fingers crossed.
