Does anyone know the thread on the Transformer fuel filler neck circa 1989 ??

I measured the male thread at ...
2.117" / 2.120" o/d
0.098" / 0.100" pitch

Went to my "Zeus" reference table from when I was an apprentice and went straight to it !

2.116" o/d
2.000" core dia
0.0909" pitch

Blimey! Zeus tables! I have a set of those. Very handy for drill sizes for tapping threads. All the Trig stuff was always well beyond me. Well done Phil.
