Default Re: 2-Stroke HT Cross Flow Design

the air fuel mix comes in from the side through the transfer ports, a proper combustion chamber design uses the piston top and cyclinder head shape to promote a full fuel burn, this includes a swirl effect to keep the mix from separating, and give a proper flame front. on a piston port 2 stroke like the ht the actual intake path is down through the case and up around the cyclinder to the top of the piston, if you look down the carb and intake you will never see the top of the piston from that view.
