Will i feel a difference with porting and polishing

[enduro400rider]

i m think about having my 400ex motor ported and polished but will i feel a gain in power? the motor mods i have now are
XR400 head gasket, Hot cam stage 2, Yoshi complete pipe, UNI air filter, and a qwicksilver carb.

Yeah, a little bit but if you bored it out it would make more power with those mods.

U will notice it, But not like u would in a 2 stroke! Its a good investment But goes alot better with a motorkit!
