Tapping upper fairing thread

[abruzzi]

I’m going though my new-to-me 2006 Ulysses, and I discovered that the 6 threaded holes that hold the upper fairing in place bunged up pretty badly. One threads well, two don’t tighten at all, and three I can’t run a #10-32 bolt in more than a centimeter. The bolts I pulled out were all different, so they screwed the threads up pretty badly. I assume I’m going to have to tap larger diameter threads in there. Has anyone done this? I was thinking M6. It’s a little smaller diameter than 1/4-20, and just barely small enough that I won’t have to drill larger holes in the fairing piece.

You may need to find a j-nut or u-nut

You could try Helicoiling them.

I had the same problem. Drilled them out and re-threaded then to M6.
Got some black headed m6 button head torx bolts and some black plastic washer.
Much better and easier to remove, which is good considering that since then have had to remove the
instrument cluster twice, fix wiring problems with the harness at the neck twice, installed heated grips
so had to remove the fairing twice cos i messed upp the wiring the first time and each time I had to remove that fairing but without
worrying about the bolts.

My 06 Uly had 10-32 threads in the upper fairing. It also came with a few mismatched fasteners. I cleaned up the threads with a 10-32 tap and replaced the fasteners with 3/4 length 10-32 stainless from a big box store. Put a little never seize in the holes before refastening. Unsnapped all the connectors and put some dialectic grease on them and cleaned up the grounds. Installed some cool flush led turn signals. I will try and post a picture in a separate tread.
