I have to head to work at 3:30 in the morning. Anybody have any thoughts about how to make my bike quieter on start up and fast idle? It’s a KLR 650 with an aftermarket muffler. It’s not straight pipe loud, but a thumper is going to thump.

I’m currently looking to see if I can find an additional baffle for the exhaus. That I can just slip in real quick on startup.

I’ve talked to my neighbors (the ones I care about) and so far they haven’t said it’s a problem, but they did say it woke them up once or twice. So I figure it wouldn’t be bad to try to do a little something.

Any thoughts are welcome

    Put the factory muffler back on? 😁

    Just kidding, what’s the story on the mufflers, is the factory one quiter than your aftermarket?

    I’ve seen baffles removed, and some aftermarket have removable baffles so you can put in what u need…so I’d think you’d be able to baffle it a little.

    A ooooold trick to quiet down a hot car was to stuff steel wool into the muffler and wire it in so it wouldn’t blow out. Get it inspected, leave, cut the wires and the steel wool blows out.

    Maybe you could pack a metal tube with steel wool, make it so it slides into the muffler and use a simple bailing wire through drilled holes across the pipe to retain it (or hitch retaining pins could work). Easy to remove.

    It will affect mixture, the additional backpressure will make it run a little rich, but that won’t hurt the engine.

    The pita factor is having to do this every morning, then take them out, stow them. I’d probably end up leaving them in, being lazy.
