Yesterday I repaired broken turn signal mounts. Thought I'd post some pics and a brief description for others with this problem.
The PO's wife dropped the bike on both sides in the drive way, resulting in the lower turn signal mount being broken on both sides. I decided to construct a mount out of steel reinforced epoxy putty, this stuff from JB weld.
It's probably overkill for this application; Any other sufficiently sturdy putty will work.
Here's a picture of the broken mount. The PO apparently made an attempt at re attaching the broken mount using two different kinds of putty. The job was pretty slap dash (probably he did not remove the fairing first) so step 1 was removing that crap with a drill.
With everything cleaned off:
Step 2 was to building up a "mount" using the putty. Not much technique here. I screwed the turn signal into the top mount then put the thin piece of plastic the putty came wrapped in underneath the signal. I then built up the putty until it touched the underside of the turn signal, and let it set. The stuff gets kind of warm to the touch when it sets.
Ain't it beautiful? Girl friend says it looks like a giant booger. Step 3 I painted it black just to be safe. Step 4, drill a new hole and screw in a self-tapping screw. Job done.
The only thing to be careful of here is not making the putty too thin where the screw hole is going to go. Obvious I know, but I made that mistake on the other side and when putting the screw in the putty cracked and fell apart. The wall was just too thin, so I will have to re-do that side. That stupidity aside, the plan seems to be working (so far) and feels like a better repair than using a zip tie.
