Any reason I cannot drill a couple holes in the frame just behind the neck and above the hole all the harnesses pass through ?
I recently bought a vintage Avon half fairing and need some holes for mounting.

it might be better to weld some nuts on, or an extra tube or something.

I am no engineer but the idea of drilling holes in frames worries me
i know that a lot of custom guys run the wiring inside the frame.
Obviously with a T140, you need to worry about not drilling into the actual spine.

The two holes would be through the two large gusset that attaches the top tube and neck on each side of the frame.

Take a look at fairing mounts as fitted to 1971 frames.There are two tubes welded onto the headstock.These were not on the 1972 frame.

yeah, the tubes were as a replacement for the old mounts on earlier bikes.

i realise that you were aiming on using the gussets but at some point, extra holes and stress render the gussets useless. Not being an engineer, i don't know where that point is, hence my hesitation to add random holes.
The advantage of a tube is that you can add some studding through the tube and create almost anything

Yes, I've seen those and that is a option. Basically I'm trying to avoid welding. I do not have the equipment or a way to transport the mostly assembled bike to a shop.
