How to make Dirt bike quiet cr80 expert 2 stroke?

Question

I have a 97 cr80 expert great bike but i live in hippy bay area and people here complaine too much please help me make it quiet

Answer 1

Try a stock exhaust system. They are the quietest! Being as your bike is a 97, it is probably due for a silencer repacking.

Over time, the fiberglass material that helps to absorb the sound actually breaks down and loses it's ability to muffle the noise. It is cheap, and fairly easy to do.

Your local dealer can give you better instructions on how to do it, and may even do it for you at a low cost.

Good luck!

Answer 2

If you still have the stock exhaust, have the silencer repacked. Then buy one of the silencer plugs to use when you wash the bike. Getting the packing wet ruins it.

Answer 3

You need a silencer and if you already have one you need a better one. If you know a GOOD welder you can get them to double the metal around the expansion chamber too.Sometimes the intake roar can be too loud too, you might look into encasing it a bit.

Answer 4

ill tell ya what i did for my bike

get a baked bean can (No ring pull)

cut a circle on one end to fit your muffler diametre, clean all the beans out which takes a few minutes, use a s***w driver

to put about 20 or so holes in the other side then put it on ya bike.

From a distance silences by about 40-50 percent but that

was on my 4 stroke

before you ride make sure there are enuf holes

cheap n easy i wouldnt know where 2 get a silencer

Answer 5

The stock system is usually as quite as it gets.  However there are other things you can try.  Buy an after market muffler like Supertrapp that allows you to tune the the output noise.

Also you can try wrapping the header and pipe to deaden the noise coming through the side of the pipe.  Many factory street bike pipes are double walled to reduce noise.
