bike hiccups under moderate acceleration

[hamjam]

Now bet your wonderin' how on God's free earth is that related . Easy-peasy......when throttle backs off to an almost cruisin' rpm, PORTED vacuum to vacuum advance rotates advance assembly moving pickup coil wires, which over decades of that happening weakins wires INTERNALLY, breaking them.....then rotating back makes internal contact when under load(manifold vacuum only).......hope that helped .

excellent explanation

MP: Good to see you actually DO have a sense of humor
Greg: no problem......I would of called you anyways to make sure all was okay if you HADN'T commented .

LOL......you know you can't get away without a comment from the BA.

I've always soldered. But maybe BUTT connectors would work too.

The biggest thing I've found that make repairs fail is the connections or the shrink tubing not flexing enough and it'll break again shortly right at the edge of the repair. If I put the repair inside the little wire clamp (which is normally where the wires break) the repair lasts much longer.

You can pull a little extra wire out of the harness if your careful to give you a little more slack.

The wire was broken near the clamp. I affixed the repair behind the clamp and actuated the vac diaphram and theres plenty of wire. Should last a while.

Good find and fix bikerdave .

I feel the need to weigh in here. I think an amateur will have better luck with a crimp than with solder. I am professionally trained, so I know exactly my weakness in soldering skill. I believe a crimp splice is less likely to break again. There is good reason why almost all of the connections on a jet airplane are crimped. Greg, please don't take that as me saying you can't make a good solder joint. I'm sure you do it better than me.

I like this video. Not airplane legal, but outstanding for our purposes. Use a naked butt splice and heat shrink as per this video and it's done right.

Excellent video, Marty!

Simple, but concise explanation ... it definitely sold me on using the naked butt connector/crimp method instead of soldering.
