My STOCK silencer on my RM250 is full of burned oil. The packing they sell in stores is 1/3 as dense as the stock packing, so I was just wondering if it was a good idea to pour some gasoline in my silencer, cap it off, and let it sit for a while to wash all the grime out. Has anyone done this before? Would it just be better to repack the silencer? Oh yea, and obviously I would let the gas evaporate before i put the silencer back on the bike adn ran it.
