i took my intake off today i have a ssr125c3 and the gasgets dont match the hole . so i cut them to match and i dremeled the in take till all the holes match and wow way smoother and better responce . so check your bikes and get to work .
Sorry but yo udo not polish the intake you polish exhaust ports. You leave the intake rough creating more turbulance and it atmoizes the air the fuel better. So thinking you just added hp when in fact you prolly robbed some hp. So check your intake and get another one.
