So to make a long story longer, I decided to ride my 1981 R80g/s to Port Angeles from Portland a couple days before christmas to join family. All was well until about 50 miles before my destination and my bike was surging and cutting out. It felt similar to the effect to running out of fuel. I pulled over and the bike died. It would not start. I did three things to try to diagnose the problem. I checked my plugs and they seemed ok. I took my tank off and and checked my wire connections to my coil. One was quite corroded, the right one. I pulled it and cleaned it up and reconnected. Put the tank on and boom it started up beautifully. Rode the last 50 miles without a stutter. I concluded that it was either a bad connection on the coil or there was a bit of dirt caught in the petcock valve and closing and reopening cleared it. Next day was so nice out and was headed back to Portland to spend time with other family. The bike started fine and for 55 miles was perfect until the problem reoccured. I checked the ignition coil again and noticed it was cracked. I did a quick google and found some useful information about THE grey ignition coils prone to cracking and malfunctioning. I had an extra plug and tested coil connections by disconnecting the plug wire cap and inserting the extra plug and looked for spark. The right actually sparked fine and the left was not sparking. I waited a while because I read that if left to cool the coil will begin working again. I waited and it began to spark again. I rode the bike again and the problem occurred again and then I had a back fire that was quite loud. I decided to find other ways to get the bike home. I got a uhaul and picked the bike up. it was dark at this time and since I did not have any help to get the bike up the ramp I decided to ride it up. I started the bike and the cutout started to happen right away. I look down to the left spark plug cap and it was glowing with every fire to that plug. Then it would stop and the bike would run fine. Back and forth. I crossed my fingers, revved it up, and rode it up the ramp. Now I was thinking I also had a bad spark plug wire as well, because it was glowing through a hairline crack. I got home and ordered a new Bosch ignition coil, new wd7c+ plugs gapped between .6 - .7 mm. and new plug wires rated at 1kohm resistance. It seemed to be running better but had more resistance in idle and acceleration and more vibration. I rode home tonight and I felt a bit of surge once or twice. I started reading snowbums sight on plugs and wires and I read there that coils from 1981 - on should have 5kohm resistant plug caps or you could damage the ignition. One other vital piece of information: The night before I left, the headlight was intermittently cutting out. I got home and was moving the handle bars back and forth with the power on. Well I heard a short engage when the light cut out. I turned of the power off and investigated the wiring coming from the headlight and the control switches. Almost all of them were damaged and just twisted together and taped up. I spent most of the night soldering and properly connecting the wires until I could get back to it and do a better more thorough job. Since everything has been working fine in that department but the shorting sound could have done something. I am a bit frustrated as I bought this bike and there was a lot of poor workmanship. I have fixed a lot of things already but this is a big one and I want to make things right. I have had the biked checked out when I bought it and compression was at 130, so no problems there. I changed all the fluids, when it came to the oil, whoever changed the oil prior to my purchase had the o-ring and the shim reversed. Prior to changing the oil the oil pressure light only came on a couple of times when hard breaking and was alleviated by topping off the oil. Since the oil change the oil pressure light has not come on. I have adjusted the valves, synced the carbs with a twinmax. The bike was running beautifully until I was the thick of some cold salty downpour on the hood canal and broke down. I know this is a lot of info but just need some sound advice.
