Big_Poppy,
You will void your warranty on the motor the moment you do the big bore. You may actually void transmission major work if Georgia ask the dealer anything that would show major mods to torque and the possibility of metal debris.
Doing this mod on a warranted bike would be very risky if you value the warranty for the motor and transmission. If the warranty is not a big issue to you in those areas then go for it.
They will still warrant the electrical stuff, master cylinders, ect.
