How do you change the silencer packing?
I have a 1979 RM80c and, its really loud!!!!! its a 2 stroke. Its so loud, my dad wont let me start it up because we live in the city. so how would you change it? would you take the end of the muffler off and take the inside out somehow or what? inside, the muffler, there is a round thing with a bunch of circle holes in it all over, what is that? please help..... any information or websites is appreciated. Thanks,
