Yank,
I have an old Shiv Pathak 60-2 wheel assembly. It mounts to the 6mm bolts on the inside of the crank pulley. There is a pressed aluminum cup (probably spun) that extends from the bottom of the pulley up to the face of the pulley.
Argghh. Fail at ascii art. Edge view is like a big washer viewed on edge, sitting on top of a pipe whose diameter matches the ID of the pulley. Then a flat circular plate is on the bottom. Holes are drilled in the circular plate to accommodate the crank bolt and pulley bolts. The Pathak piece is made entirely of one piece. Then a wheel is bolted to the big washer.
The sensor is a 3/8" diameter chisel edge sensor from Electromotive. Gap is close enough - but not too close. Haven't measured it lately - it is about 1 mm.
1.8L engine.

This is totally the blind leading the blind but FWIW i was told to space the VR sensor the thickness of a business card from the disk.
Did you build the pull up for the VR signal? I somewhat remember there being a voltage pull up option for it..
then again the VR may not even be your problem.

Unless Brain contradicts me, I think my VR is fine. Plenty of signal. Seems to be triggering fine. I have a 1 mm gap for the VR. My clamp for the VR pickup is very squirrelly, can't change one thing at a time. The pickup is centered on the tooth.
Personally I would not make the gap 0.25 mm or so, unless you check the wheel is perfectly centered on the crank pulley. More chances for something to go wrong... 0.5-1.0 mm should be fine. I'm getting > 600 mV peak to peak at 1 mm at cranking speeds. The voltage swing gets larger at greater rpms.
