| Hey everyone, When I got my pipes (Hard Krome American Classics) put on the bike, I noticed a bit of burbling and stuff during deceleration. I got the Stage 1 Dynojet kit and had the local dealership put the kit on. After I got it back, I noticed that when I rev up the engine at idle, it seems to respond quicker. But during deceleration it burbles a lot louder and pops like crazy (sounds like it is backfiring) at times. What would be the reasoning for it to be running like this? I've got a few friends that have Harleys with aftermarket pipes and I've never heard theirs do that. Can anyone tell me what's going on? Thanks, Adam |

First to look at: Did you adjust your idle/air mixture screw after you installed the jet kit? If not, screw it in until it just touches the metal, and then back it out two and a half turns. (If you have two carbs, do this for both.) Second: If you've done that. It could be your PAIR valve on the left side of the bike. Easy fix. Twenty dollar PAIR valve removal kit from Mocc's Place. Third: If you've done the above. You could be running rich in the Pilot circuit. Popping on decel is usually a symptom of the Pilot circuit being too lean. However, either of the two above could be the culprit. The bikes come from the factory with the idle/mixture screws set lean. It could be that simple of a fix if you've never adjusted them. Also, check your header connections and make sure you don't have any leaks at the exhaust flange where it bolts to the head.

| Oh, and I forgot the REALLY obvious....did you replace your exhaust gaskets when you put the new exhaust on?

| I will check that stuff with the dealership when I get home tonight and see what they say. I know that when I put the new exhaust on, I did replace the crush gasket on the one that connects to the head on the front cylinder. The one that connects to the rear cylinder uses part of the existing piping that goes behing the engine then clamps to the rest of the pipe. On this part, there was no gasket to replace since it just clamped onto that existing part of pipe. I will double check that the bolts on the head are tight and that the clamp is tight. Thanks for all of your help! Adam |

| In Training ![]() | My 03 does the same thing with V&H exhaust, K&N's and Stage 2 jet kit. I notice it more as I roll into the throttle from a decel. I adjusted the mixture screw several times and checked for leaks as well, to no avail. How can the PAIR valve cause this? I ran my bike for a while with the exhaust and no jet kit and it never popped until the Stage 2 kit went in.

Check here [url=http://www.motorcycle-journal.com/forum/showthread.php?t=8570&highlight=Pair+valve]at this thread[/img] for an explanation of why and how the pair valve works. Good info on how it could cause a popping or backfire on decel with aftermarket pipes. However, you mentioned the Stage 2 kit.....could be the Pilot circuit...?

It's possible it could be the pilot jet. I haven't been able to tinker with my bike until recently. I'll try the pair valve delete and see what that does, I just hope I can get it here by Tues. though.

| In Training ![]() | The popping and gurgling are GONE, and all I did was pull and plug the lines going to the cylinders. I used a couple of short, large diameter bolts (7/16" I think) and hose clamps, put the cover back on and took it for a ride. All seems well now. I'm still going to get the PAIR delete so I can remove all of that crap, but I had to try it the DIY way just to see if that was the problem, and it was.

| I just ordered the pair valve removal kit today. Hopefully it will be here in the next few days so that I can get it on this weekend. I will let you all know if that fixes the problem. Adam |

| Good luck Adam. Matt....congrats on the fix. BTW Matt......Nice Lightning in the sig pic. I owned a '93. I got rid of it to get one of them there newfangled SuperCabs ('97 model) in '96 with the suicide doors. Damn when the SuperCab was new. It got a ton of attention all over town. I'd come out of a store to find hand and forehead prints all over my windows. I'd educated my wife about the Lightning, and how rare they were. She didn't realize there was a guy two neighborhoods over that had the same color. He had the steel bumper, and I had the Nerf bumper. She didn't know the difference. Anyway, she spots this guy's girlfriend driving his truck. She and my sister-in-law followed this poor girl around and confronted her when she finally parked. You know, "Why are you driving my husbands truck?" Needless to say my wife got embarassed mightily!!!!

I wonder what was going through your wifes mind while she was following that "other girl" in your truck? Ford will be pulling the plug on SVT by April 1st of this year, so my truck will become more of a collectors item. No more SVT Cobra, SVT Lightning or SVT anything for that matter. My brother purchased this truck new in 94 (with the tube bumper) and then sold it to me in 96. Now back to the topic at hand

| The kit that I got has instructions for our bikes, so that should be suitable. Thank you very much for the extra info though. I didn't have time this last weekend to get to it, so hopefully it will be warm enough this weekend to get to it. I will keep you all updated. Thanks again, Adam |

| I FINALLY got the pair valve removal kit installed this weekend and it stopped all of the popping that it was doing on deceleration. Thanks to everyone for all of your help! Adam |
