I have a honda shadow ace vt750 bike sat up a while and cleaned carbs started up and idles fine and runs fine on quarter throttle it has slight miss and when I slow down it pops and backfires unless I pull clutch in. I have cobra pipes and not sure if previous owner re jetted any info will help

My first guess would be that the fuel mixture is off. This can be caused by improperly sized jets or missed contamination in the carb.
