What a PITA. (outter fairing brass threads R & R)
The weather man said all week that it was going to be sunny and 45 deg. Woke up this morning and it's snowing. Very disappointing!
So I decided to fix my stripped brass thread on the lower part of my outer fairing. I cross threaded it last time I had if off. I ran a tap down it and was able to get it secured, but I couldn't get it as tight as it needed to be. I bought the new part and thought this will be easy, I can just unscrew the old one and screw in the new. . . . NOT. Man was that a job. Turns out the old one is not threaded in there, so I ended up having to gently drill out the old one to install the new one. Talk about nerves, I thought for sure I was going to mess something up.
Everything worked out fine, the new threads are in, and it's all back together and ready for our next thaw.

Surprised it was snowing down there! It was cloudy up here in DuBois, but we hovered around 42 most of the afternoon, then the sun came out for a bit even.
And I hope I never have to deal with those brass inserts...

For the next Guy:
brass and aluminum are softer than steel.
it is best to start steel into brass by hand, if you are not "sure" reverse the screw before starting- when you feel a slight "click".
the threads will now be aligned, and you can start the screw as normal.
dissimilar metals can form a hard-to-break bond, an anti sieze paste on the threads will help prevent this, especially where heat/cold cycles or strong electrical current may be present such as on sparkplug threads

Glad you got it handled. I am always very particular with I try to start those 4 screws. Best to do it by hand. If you can't turn them by hand they are cross threaded. Learned long ago not to force threads. I never torque it to the specs either. I usually torque it a tad under the bottom torque spec. Those brass threads are soft and it does not take much to damage them.
