I'm going to buy the bolt-ons in preparation for next year's woods port (and this years fun) and I was wondering when I should get carbs and what size? I currently have an FMF Gnarly exhaust. I'm adding reeds, head/domes, timing plate, K&N lid and dial-a-jet...which is another reason I'm asking. I want to stay on pump gas and I'd like low end power. Thanks.
