Alright, I fixed the exhaust leak and the carb fitment problem on my 73 CL350, and now it runs like crap!! So a rejetting of my 450 carbs is in order. The only mods I have made on the 450 carbs are the Uni Filter foam socks. PLEASE give me some type of guesstimation on jet sizes. I know its trial and error but its a pita to remove that exhaust!
