Pipes "Wheezing" on decel

[canoli]

'92 XLH 1200 with Super E -

I bought Bassani "Pro Street" pipes 2 into 2 and they're great but they "wheeze" a bit on deceleration. Not a lot but enough to be noticeable. Power and throttle response are good and they sound good too, at idle and when I twist the wick. But letting off produces a bit of a a wheezy sound.

They came with removable baffles but I doubt removing them will help, probably make it worse.

I miss Cycleshack their M Pipes were the best. These Bassani sound very much like them except on decel where they produce a bit of wheeziness.

EDIT: If you're considering these you should know that your boot will sit very close to the pipe unless you make a point to keep your foot toward the outside of the peg. If you don't your boot will meet the same fate as mine: a melted heel. The Bassani heat shields don't come down far enough to protect your boot so I'll try fabricating my own. A fun project but I wish I didn't have to do it. Spend and learn as they say!

so what is wheezy?
little rascal???

If it is rascal, then some sort of thuner torqe inserts could solve the problem. My pipes had that sort of sound which went away when I instalet those...

Thanks for the suggestions you guys.

But yipes! $40 for a coated thumb screw? If this is what you're referring to...

I may try it but probably go the hardware store route.

Yes, I made them myself. I also made two different diameters to see, which will suit me better. I just bought the washers, made them concave and weld them to bolts so that the hole in the middle is closed. Cheap and efective...

For sure. Can you recommend something? I'm calling it wheezing, maybe that's not a good description. They sound like drag pipes after a roll on when you come off the throttle.

With 2>1 systems or with the Cycle Shack M pipes I had before there's a deep rumble throughout the RPM range. These Bassani pipes produce that too, except on decel where I hear a wheezy, "airy" sound mixed in.

Like I said it isn't horrible and I'm getting used to it. But it'd be nice to fix it!

are they baffled?? i run the danmoto and have no issues with or without the baffle. if you are experiencing pop or other weird noises on decel, i would check carb settings like throttle plate too far open, drilled slide or bowl level. normally on decel, the mix is too lean to cause an issue so check jetting also.

They have baffles. I may remove them eventually but I doubt that'll improve the sound. The bike runs good no popping, the plugs look good. There's just an airy, broken-up sort of sound on decel. I'm basically used to it now - it isn't that bad.

Now if I could only find a heat shield that protects my boot heel. Such a stupid design running the pipe so close to the peg. Guess I should've looked at them better before I blew $600. Live and learn - they'll do for awhile.
