RE: "cc" "hp" "torque"???
splcrazy;
not really. the reason most "4strokes" engines have more than 1 ring is that they have engine oil at the bottom that the "oil" ring keeps out...
2 strokes dont have engine oil so it only needs the one compression ring
the way to get more compression is to shave the cylinder which you'ld have to enlongate your ports etc..... not recommended.. there are easier ways... like twin turbos LOL
