26mm carb

hi could any one tell me what efect the 26mm standerd carb would have on a standerd px200 with a sip perfomance pipe and what jets i shold use i am useing a 118 with the standerd 24/24 with atuo lube any advice would be aprecated[:dance3:] [:angry:]

it really isnt worth the effort fitting a 26mm to a standard engine .whilst it may run a tad cooler its outweighed by probable bogging down.the porting on a standard barrel wont benefit from it.slap a mallossi barrel on it as well and youre in business!!
