Just for clarity, the port is closed while the brake is applied. Any air bubbles are compressed into smaller bubbles. With luck the small bubbles migrate upward to the MC, consolidate there and are released into the reservoir when the brake is released.
Exactly what happened to the first one I did and how I resolved it. You do have to keep track of that particular cover and where it goes the next time you have it off.

The 1980 Special I bought had three stripped out. I used a Helicoil on all three with good success. In addition to the good advice above two points:
1. Take your time and make sure your drill is perpendicular.
2. Just grind a bit of the tip off the standard Helicoil tap and presto you have a...

To my surprise the rear wheel would not come off unless I unattached the rear brake caliper from its mount. The tire would not clear through the gap no matter what angle I tried. This...
Thanks for all that. Yes, I have done all the resistance checks and all is fine. It is purely TCI triggering related as the bike runs fine with the alternator disabled (no magnetic field from the rotor).

The bike is a stock 1980 Special.
The bike had some running issues. Runs fine with the R/R unplugged. Tried the rare earth magnet install and it ran fine for almost 200 kms before the same running issue returned. Again runs fine with the R/R unplugged. There is a post where someone else...
