So yesterday eve and this morning was elbow grease time. The bike's header pipes and silencers needed cleaning, since they had a rusty brown colour. After searching this forum and the net in general I found some pointers and started disassembling the bike last night to get to all the necessary nooks and crannies.
I also bought some supplies at the local hardware:
1200 wet sand paper
2000 sanding-sponge-thingy.
I soon realised that I would have to take of the whole pannier system on the bike and didn't feel like going through with all of that so I knew that blood will be drawn from getting to all the hard to reach spots.
After testing the 1200 paper on the very bad areas I realised that I got into something that might take up the whole of Saturday. The 1200 got rid of the brown baked whatever, but it as soon as you hit the bare metal it was too coarse. I then changed over to the sponge-thingy. After an hour and a half of sanding I had enough and decided to go to the hardware store and buy one of those round sanding jobbies that fits on a drill. I then cut the sponge-thingy into a nice circle with a small hole in the centre and made it fit onto the sanding apparatus.
Dashed some Silvo on the new apparatus and started up the drill. AMAZING! Within 3 minutes the I finished the one silencer and it was shining nicely.
For the hard to reach places I cut a long strip out of the sponge-thingy and wrapped it around the pipe and pulled to-and-fro for about 2-3 minutes. When the Silvo liquid becomes powdery you know its done or might need just another small blob with another 1-2 minutes of sanding.
I've attached some peekchas.
PS Just remember to pacify the Stainless with a 20-30% Nitric acid after the sanding. Hope this was helpful.
