No spark with COP's?! Wtf?!

kcoop99 · May 1, 2015

I can have my 89 sitting for weeks and go out to fire it up and it will start right up. I ride for a while or even just let it warm up, turn it off, and it won't fire back up for a while. I have fixed EVERYTHING that is associated with the hot start issue. I took it to Mark a few weeks ago and had the carbs all tuned up. It ran like a champ!! What is going on? It sounds like it is not getting a spark or maybe gas (yes, there is gas in it). Anyone have this issue? All I can suspect are the COP's?? I will post the video below.

Have you checked the pick ups?

Starts up fine when cold but after it warms up, either you turn it off and it wont start back up until it cools, or it dies out by itself as it reaches OT. Sounds Familiar??

What's the gap set at?

Pickup is the suspect right now. Gaps are good.

My volt meter is giving me readings all over the place.

You may have a rectifier problem sounds like to me.

I will post a pic but I'm pretty sure with all of the electrical work I have done that the coil was not connected entirely. I am thinking it was a very simple fix. I'll keep this updated.

Just to give some closure to this thread, Morley sent me his traveling electric kit and I replaced the pick up coils. Nothing. Swapped out the ignition unit and voila!!! Sooo.... Lesson here is always trust Morley to come through!

Well, unless you had a loose connector in the primary circuit, the ignition box or the pick up coils are what I would consider to be the issue. Sean's electrical loaner fixes another rider's issues.
