Has anyone else got the same problem with the under engine exhaust being badly corroded? The pipe (somewhat twisty - seems gives better balance between the cylinders) is under the bike so hence has to deal with a lot of water splash when riding in wet conditions, I'm a fair weather biker so don't go out in the rain but the exhaust is still very corroded. I'll most certainly have to remove the whole lot before winter to give it a good clean and repaint it as best as I can, been told that spray on barbeque paint works fine.
