help, preferance?

[EXDUNER127]

What do you guys prefer i do to, i am planning to get a high comp piston and hot cam stg2.

high comp piston std bore, hot cam stg2 or

piston w/.080 over bore, hot cam stg 2.

will there be a difference because if i can avoid boring my head would be cool but if it means more power i might as well do it.

if your cylinder is fine why bore? by using the lighter piston and higher compression you will increase the rpm and speed of rpm quite a bit. i don't think i would bore mine just to gain cylinder size unless it was a drastic change. and from what i've seen the bikes that are killing the 440's are generally the smaller piston bikes.
