Fred. So, to fully understand this since I'm slow, the video you have linked on this thread is with this hose blocked? Tell us more about where this hose is.

Look [url=http://cb1100forum.com/forum/showthread.php?tid=1824]here for a PAIR Valve thread.

Cheers

Nice sound, fruity yet mellow. Gruff yet subtle. Naughty yet nice.

Man, I should have gone into advertising.

A remarkably accurate description of my farts.

Seriously? What is this 4th grade?

I see that didn't take long. 1 day.

C'mon fellas

Alright guys, everyone knows that The ferret has his hands full around here. The majority of folks who visit this place are very appreciative of his tact and judgement. Please don't try to pick a fight with the man in charge.

So...to get this back on a more appropriate track.... Is the popping on decel either harmful to the engine or indicative of harm being done to the engine? If so, in what ways?

[fredkb_imp]

From what I have read, the pair valve was designed for epa requirements and the popping on decel is the pair valve doing its job. No harm, just some people do not like the sound when amplified by aftermarket exhaust. I have read on other forums that popping on decel on a carburated bike could indicate a lean condition, or is it a rich condition?. On EFI, the oxygen sensor analyzes the exhaust gasses for optimal fuel ratio and the ECM compensates by adjusting fuel injection pulse lengths and fuel timing. I may be wrong, but that is my understanding. Maybe some one with more factual knowledge can chime in.
