I just installed a N.O.S. (new old stock) set of Jardine Rumblers (Fishtails, BTW) and love the new sound. Except ......the poping and "chuffing" sounds are even more pronounced. Now I know that marbleing will solve the popping problem but do any of you all get a random "chuff" or "puff" sound even when the bike is at idle?

Thanks as always ............ Roger

To your knowledge, has the air/fuel mixture screws been adjusted? Once you install marbles, you definitely will have to adjust the A/F screws.
