2busa thanks. If I read you right you think I need to replace whatever is inside melted shrink wrap with a fuse, correct ?
YW. Yes. If you are saying the loose spark stick was not it, then what looks like a fuse-able link, could kill that 5% of the drive-ability you still feel. See, I have the Tfi fuel cutter. They run with tiny pots you screw turn for fuel trim. I use a fuse for this piggy with the battery or hot wire having that fuse between unit and battery.
I just finished building a chopper using old Sportster parts for the wiring. The bike runs perfect. But if this one fuse blows, the bike runs like it's hitting the rpm limiter, because it runs on one cylinder and the other sorta kicks in every now and then to keep the engine running. That made me thing "fuse."
And whatever setup they use as a fuse from the PC to battery, that might be the same kind of drive-ability stumble, where it is not flowing through that melted part of what looks like some sort of fuse. I'd love to rip a razor across it, see what is under it. It's just shrink wrap around that fuse like thing. It looks like you can pull those ends apart real easy. They look like early Honda male/female snap together sockets.
You can take that melted part out, take your fuse, peel the wire cover away so you can spool the copper wire round enough to hold in the socket fitting for the test. If that is the dramatic 5% change, the bike is back to normal. I would bring more fuses just in case that 'stability' problem occurs.
Only tape I found coming off was little piece around 3 wires going into TPS. Is this area you refer to regarding glue instead of elec tape ?
Yes. I have an example of the glue protecting the exposed ribbon and other parts re-glued back on the unit.
What exactly is this thing doing (part under shrink wrap) ?
What is its purpose and by saying ding ding do you think I may have gotten lucky and found my smoking gun ?
I am not certain what is under that wrap, but I would remove and replace that part you noticed. That guess is how I associate the chopper's fuse with your PC being a "Drive-ability" problem to question. With all the photos pointing the way, I could only find something very obvious within the loop of the PC > is not the problem, but the burnt fuse instead.
That is why if the normal store bought fuse cleans the tune
