Genuine need for info. Currently running a 175 iron kit through the air box (drilled out) with a 42mm clubman and a SH1/20 carb. I am thinking of trying a 22mm carb but need a start point for jetting. All I can find is either for a 150 or 200cc. My current jetting on the SH1/20 is as for a TV 175 S3 with a slightly larger main to account for the clubman exhaust and now the barrel is run in the improvement in performance over my previous iron 150 barrel isn't much Hoping for a bit more with the slightly bigger carb.
Any advice (relevant) greatly appreciated as usual
Tony
