D&D Gatcat exhaust installed, gurgling-pop on shifts
Anyone else here with D&D Fatcat that has this? Read on another forum it's because the D&D head tubes are equal length. Bike is a 2001 carbureted, Andrews 37G, 10:1, Killer Carb CV40.
When I let off the gas to shift up, i get a gurgling sound, like exhaust scavenging or so.ething.
Could it be the tune is too lean? Or too rich?
Just had an RB Racing Black Hole on there last week and it didn't do this.
