I have a yoshimura duplex full exhaust and my carbs have 146 main jets with the stock needles and airbox. When i decelerate i hear a popping noise. Does anyon know what could be causing this? the bike run's realy well. I can tell a difference like night and day. P.S......Dont try the Graves airbox is is worthless for dragracing, it kills the bottom end. It also makes the gastank stick up.

More than likely if you are running 146 mains it is running to rich,man that is a big step from stock. You are talking about popping through the exhaust,correct?
