talk operated,
if you want nore torque, go down on teeth for the clutchbell, i just put an 11 tooth on mine and it rips any little bump and the front end is off the ground. the HPI 100cc tank is a direct drop in part for the mt-2. as far as the arm mounts get the ones from new era, cuz they are meade for the mt2, the original mt has not differential in the front (2wd) i think, so the mounts are way different.
