Well, this can't be good…. While prepping my 1993 VFR750 last fall for winter storage, I couldn't help but notice this unusual scene. A solidified, sticky, honey-colored goo had appeared on the lift handle, obviously originating from above, its source hidden under the tail fairing. Some investigation revealed that the Ignition Control Module (ICM) was bleeding this stuff. It wasn't actively leaking, so I decided it could wait till the VFR came up on the winter schedule.

On the bench, I didn't get much insight beyond the obvious — the plastic case had been oozing this stuff but no more had accumulated over winter storage, so maybe this only occurred when running and warmed? Don't know, but I strongly suspect that there's no repair to be had here. Fortunately, my parts stash included an ICM salvaged a few years ago from a running 1990 model, and an online check showed the same part number used from 1990-93. A quick plug & play swap, test run, and voila, back in business. The moral of the story; keep your old parts.
