Thought my true to OEM restoration of my 84 aircooled 240 WR fitting the noise reducing clam shell covers on the diverge cone of the exhaust was a nice touch until I noticed the hidden corrosion today. The fiber glass matting absorbs water during washing the bike and sits damp slowly rusting away the exhaust. Have lots of holes that will need repair or replacement. Who supplies exhaust pipes for the 1984 240/250 air cooled bikes? I know HVA Factory have some but are there other suppliers? Be nice to unleash a few more HP’s if possible.
