Yup, brown goo. That's yer culprit.

How do the contacts look in the spark plug caps? The front cyl cap has been known to corrode to dust, internally.

x3 on you need a new cam sensor and the above is the best option IMO for a fix and upgrade in one.

Great! I'll get the parts ordered today. A buddy has an extra one so I'm gonna try it out to just double check.

Thanks for all the help!

Here's a very reasonable option from Standard Motor Products @1/5 the cost of OEM... I use them in my 98 and my 77...

Amazon

Well, replaced the cam sensor with a used but working one and still no spark to the front cylinder. I have checked and doubled checked the wiring and connections till I'm blue in the face.

Rotor was tight on the cam?

You have a known good coil, you have a known good ignition module, ohm the wires at the ECM going to the coil and plugged in to the coil - should be able to get 3 ohms when checking the positive and each side of the negative at the ECM connector. You should get continuity between the 3 wires at the module connector and ECM connector on each wire, just to confirm wires are good. Still look at the ECM connector pins for corrosion or dark pins meaning burnt, check the ignition module wire connector pins for corrosion. For the hell of it check your battery cables on the battery, It is starting to look like the ECM isn't sending out a ground to fire one side of the coil but confirm wiring is good but like mentioned earlier a ECM is the last item to replace.

If the wires check out good you may swap the ECM off your buddy's bike if needed, 95-96 97-98 ECM will plug in to test it, 97-98 is programmable being the only difference.
Engine position sensor controls the injectors and nothing to do with this if that is floating in you head.
