So, after the return from the Whitehorse rally I had a bike that looked like this. Even after a good cleaning to remove the calcium chloride & mud, the pipes were still stained quite black and ugly.
Removed them and as was suggested in another post went at them with #600 then #1000 wet/dry paper to remove the heavily blackend areas.
Finished them with a bench mounted polisher using a 8 inch diameter cotton wheel and medium buffing compound. And knowing they will quickly return to their straw yellow colour in short order I doubt I'll be making this part of the regular upkeep due to the time involved. ??? It was just a little sad to see a 2012 model looking that ugly. ::007::
