So ive recently got into performance mods. Mainly for speed. And torque balance. 32 tooth, sbp x chamber and a dellorto sha clone carb. I installed all of these at the same time. #65 jet in the carb extended intake manifold and 13 inch header on the pipe. From flange to very beginning of expansion bell. It starts right up. With ease I mean one turn of the pedals and bam. But when I get up to maybe 10 mph hit the gas and it like a bucking horse jerking and misfiring. Not a steady idle. Not sure what going on here. Im thing about putting the stock exhaust back on and try to tune the carb a little richer then put.the x chamber back on. Any thoights on what may be causing this?
