washed it and patched up an exhaust leak. looks like my left 4/4 cans are going to hell in a handbasket now, too.
Had a weird vibration at exactly 5k rpms, and little blips above and below it. Figured out it was my shortened kickstand against the exhaust heat shield. While I was pondering how to fix the vibration, I took some JBWeld (the stick/putty kind) and a can, couple clamps and patched the exhaust leak (it's a bubbly crack in the can, so most likely rusting through from the inside, just above the most-likely-clogged drip nipple in the bottom)
After patching this, I kicked up the kickstand again to see where it came. Now it hit the pipe clamp.
It gave me an idea.
I took a patch of buffalo leather and wrapped it around the flat plate on the rear-facing side of the kickstand (no pics, but 650 kickstands are the type with the rubber kick-nub on the bottom) and secured it with a bread tie. Used a touch of grip glue just to make sure it doesn't go anywhere.
When the stand gets kicked up, the thick leather hits the pipe clamp and is very much muted. The leather is in turn protected from the worst of the heat by the raised part of the clamp, and being as far back as it is on the pipes, it'll most likely be ok from there.
I felt pretty witty.
