- 1). Position the motorcycle on its main kickstand on a level surface. For best results, remove the exhaust pipe at the head connection with the appropriate socket and wrench. The header exhaust flange fins or securing bracket can impede the removal of burned scoring. Remove the exhaust pipe mounting brackets and pull the exhaust pipe free of the frame.
- 2). Mix a solution of mild dish washing soap and water in a bucket. Use a stiff-bristled brush to scrub the entire length of the pipe from the header location to the tailpipe end. Do not forget the muffler. Wipe the pipe dry with a towel then set it on a workbench. Do not handle the pipe with your bare hands as the oil from your skin will contaminate the surface.
- 3). Slide the header pipe flange (or bracket clamp) down the pipe and away from the scorch mark location or remove it completely. Open a jar of Blue Job chrome polish and mix the powder ingredients with water according to the directions. The consistency you want will resemble a thick paste.
- 4). Apply some of the Blue Job paste onto the flat part of a wood block. With circular motions, scrub the block over the scorched area from the end of the blue discoloration to the front of it. Overlap the front end of the pipe. Concentrate on one section of the pipe at a time. Alternate the circular scrubbing strokes with vertical strokes, scrubbing past both ends of the scorched area.
- 5). Wipe the pipe dry with a clean towel and inspect the surface. If any blue scorch marks remain, apply more paste and continue to scrub. For a smoother and more even polish, apply the Blue Job paste onto a scouring sponge and rub it into the pipe's surface. Wipe the paste residue off the pipe and buff it dry with a towel. The chrome surface should appear shiny with no discoloration.
- 6). Align the pipe with the header bracket flange. Insert the mounting bolts or screw on the flange. Realign the pipe mounting brackets and reinsert the mounting bolts into their holes. Tighten all the bolts with the socket and wrench.
