I ended up with an extra clip after a brake line maintenance job- and I can't for the life of me figure out where it came from. I've scoured my Clymer for any reference to "Clip" "retaining clip", or "Special clip" but can't find any but the few I already know about.
This clip is larger than the clip used to hold the seat hinge pin in, and I believe larger than the tank clips.
The attached picture has the mystery clip on the left, and a hinge pin clip on the right.
I didn't have tank clips when I started this process, so I'm pretty sure it's not from there. It was relatively free of grit and grime, making me think it came from under the tank or buried in the fairing somewhere.
Job: Replace the brake lines with new Spieglers
Clymer Step 1: Remove the fairing
Removed the Seat
Lifted the tank out of place and slid it back (no clips!)
Removed the knee pads
removed the storage bins
removed the lowers
removed the Radiator Shroud (That gasket with the brake line is godawful)
Removed the windshield
Removed the main fairing
Removed the ignition box so I could access the hard line between the M/C and the ABS
Removed the front fender
At this point, I'm "do the rest of it in reverse", but I can't remember where the clip came from. I've taken the tank and lowers off before. I've let the radiator shroud hang. I don't recall this clip being part of that process, so I'm guessing I just got enthusiastic but ... where?
I'm appropriately humbled, thanks for any leads. (I'm hoping I can get to it without disassembling too much...)
