well with that discription perhaps the 904 is the way to go for my thruxton since i plan to do track days and can't imagine all the power from the 994 going to the thin rear tire. did you go with new carbs or just rejet your stock ones? I also like how no machining is required with the kit. still i wonder why it doesn't have forged rods with it, i would trade for some forged rods and go with the hypeurectic pistons sorry about the spelling its early.
