I'm currently rebuilding my Warrior 350 Mikuni carb. I have a Scorpion pipe that I got cheap that has been hanging in the garage for a while and I want to install it while I am at it. The carb currently has a #145 (Stock) main, what should I get to compensate for the free-er flowing pipe? 147.5? 150? It has the stock air cleaner, but I am thinking of getting a cheap aftermarket one. Gonna pick one up tomorrow and I dont want to have to do this twice. HELP!
