[QUOTE="DualSportr, post: 157424, member: 19592"] If it's a cv style carb, the popping is due to the slide staying open, even after you let loose of the throttle - putting the choke on will increase the 'suction' and make the slide drop faster. If it's a regular carb, with a butterfly style choke, then reducing air and increasing fuel sometimes don't achieve the same goal (increasing pilot jet size may not solve the problem). If the bike is completely stock - you might look for adjustment issues, or worn carb parts that could cause the popping problem. [/QUOTE]
