I believe what causes exhaust popping is a rich condition. The reason why I believe that is because the pop you hear is unburned fuel burning up in the exhaust. If the engine is running lean, there is no fuel left to be burned. The debate is open. But please keep it friendly. Crossfires of (personal) attacks really spoils the fun of a good debate IMO. | ||

It's just the bike pouting! Mine gets upset when I roll off the throttle. | ||

mine gets upset when I roll off the throttle also. Does this come down to a timing issue? | ||

Just a thought, why dont vehicles with restrictive, stock, quiet exhausts, pop as bad? I am going out on an slightly educated limb here(read: in my experiences), that there is something to do with the instantaneous introduction of cooler air on the reversion side of the exhaust cycle during engine deceleration (due to a vacuum in the exhaust). Not all the way to the valve, only into the exhaust, causing what is known as a lean-misfire condition. Substantiation: My performance exhaust in my mildly warmed VW Jetta USED to pop quite a bit on deceleration, when the fuel system was set to stock settings, and a leaking-at-the-joints exhaust system. Riched up the fuel system overall, and popping lessened, but still there. Had exhaust shop weld up all the slip joints to my mandrel bent system, and holly cow, it almost never pops now, just winds down under spirited driving conditions. To my last Buell (2000 M2) Installed V&H slip on, lots of popping. reworked factory carb and settings, less popping. Made a custom silicone sealing sleeve for the pipe joint, even less popping. Replaced header gaskets, almost never popped after that, just winds down, even during HARD riding excersises. Just something to contemplate guys Bruce | ||

You need fresh air in there to mix with the unburned fuel. Suspect a leak around your exhaust gaskets. | ||

I needed this an hour ago. We are all right

I was going to second the one about leaking exhaust - gasket going bad, loosening clamp or busted stud. I broke a stud - was really obvious when it started popping when I rolled off the throttle. | ||

You can pop like mad if your timings off as well. | ||

Is the popping going to damage any thing though ??? My xb12 does it a little, but my road king does it a lot. And yes I read the part about the dummy pipe. Will a true dual system help it ? |
