bike strands me after 10 minutes of riding

kevbo82 · Apr 11, 2013

it just dawned on me that the connector that snapped was one of the one supplied by old britts in the power arch kit, which they describe as "crimp, shrink, solder" so they have a low temp solder in them that melts when you heat up the shrink jacket. That must have been making the connection, then after it got warm enough running the bike for 10 minutes or so the solder would flow again, kill the ignition, and me letting it sit and cool down let the solder make a connection again.

Good troubleshooting !!! It does feel great don't it, finding the fault and fixin' it yesiree. I'd say yu deserve ... a cold one

Nice one Kev! If you want to re-do that crappy terminal I have a good collection of terminals both at work and at home. And double walled glue lined heat shrink which acts as a strain relief for the wire.

Good news Kevbo.
And you wanted to sell. :shock: It’s a great feeling to sort out the little gremlins.
Yes you deserve a cold one now.

Yeah man Kev your finding allows many of us to sleep peacefully and avoid too convenient terminal devices. Don't get too smug yet, too many times after I've messed around to find and fix something I bumped something else to get loose to chase.

Low temp solder, surely not as low as typical cylinder head temperature, that would be just plain wrong to supply it with a kit for a motorcycle?

what about the filters above the tank petcocks?,..mine were toasted, trouble certainly sounds like fuel starvation,..did you check the fuel cap vent, and air blow it clear?,..plugged it can cause a vacuum in the tank situation, stopping the flow,..good luck, cheers crawf.

Good find. But I doubt if the wiring gets hot enough to flow the solder. Just some thermal expansion/contraction in the wiring most likely, or even mechanical stress like using the center stand and not.

A minuscule amount of movement caused by heat expansion is often enough to open a terminal ground connection. I think you may have hit on the solution. Been there, done that, but no T-shit. Unfortunately I had forgotten the hard earned lesson. Drawing social security has caused long term memory loss.

sounds like that solder is made to flow at about the same temp it takes to shrink the coating around the fitting. I think it's just there to double up on the connection, as your still crimping it. Interesting in my situation it actually may have kept the bike going with the broken connection. just made it strange to diagnose...

also an interesting side note, i heard back from Fred at old britts and after reviewing this thread one interesting thing he added was

"The plugs do not give a good fuel mixture reading due to the three sparks per stroke."

Good catch on the wire solder. Beer time.

Took a ride today with no issues. Hoping it stays that way. Thanks again for all the help guys, amazing community here
