Hydrodynamic of m2 much diff than L2, L1, or Mag case. Id get another L2 case. In the 250 it meant goin from 1.71 gears to 1.85 gears so it was a HUGE change. In the 200 it would be goin from 1.86 to 1.85 but the cone is WAYYYY different on m2 vs L2.Last edited by clownshoes on March 3rd, 2016, 3:26 am, edited 1 time in total.C.O.D. Jr. III
