Just bought a set of used FCR 41's for my 1340 motor. Mods are a 31-26 head, Yosh Stage I cams, and Yosh Duplex Race pipe. I was hoping that someone might have a similiar set up and could suggest baseline jetting for this combination. My local altitude is approximately 500 ft. MSL. Any help will be appreciated.. And, forgot to mention, I'll be using filters with these carbs, and compression ration is roughly 11:1..

#160's with 41's with headwork and a pipe? Wow, my stock 750 head with 38's and yosh must really be flowin'. I would've thought it needed way more than that. Are Keihin smoothbores much different than Mikunis in that respect?
