I think ignition is failing when bike gets hot
Riding with my son on back and my 2000 Dyna Wide Glide starts sputtering/cutting out after riding for about half an hour. I nursed it back home, jerking, and sputtering the whole way.
So today I replaced the vented gas cap and switched out petcock for new non-diaphragm type.
Test rode the bike for a little bit and it seemed fine. Then took the wife out tonight, and encountered the Same situation! Bike coughs, sputters threatens to die after riding for about half an hour. This time I shut it down let it cool off for about 10 or 15 minutes. Started back up and it seem to do OK getting us home.
I’ve replaced the vented gas cap with new, replaced vacuum
-diaphragm pet-**** with new non-vacuum type.
Next I plan to replace the ignition coil, the sensor, and the ignition module. Problem is I don’t know where to find a new module that is not one of those crazy programmable type. Also, I’m not sure if I need a new cam position sensor? Where that is on the bike, nor how to find a new one. Having trouble finding a shop manual in PDF as well.
any help or guidance is appreciated. Thanks in advance!

Is the bike EFI or Carb? When you talk about a sensor then I assume it is EFI. It behaves like the coil is bad. The start after a cool down is a classic symptom of a bad coil. You might want to take the cam cover off and look at the pickup. On older bikes they tend to act up and if you see any brown stuff leaking from the pickup, that is a sign that it is not well.
Not sure if you can still get the stock module from Harley for that year of bike, but you can check. Most of us with older bikes have been unable to find new stock replacement ignition parts so have had to go the Dyna or other brand routes for ignition pieces. I wouldn't be afraid of them as they are easy to install and have a couple of different settings that work fine with a stock bike. They are much simpler and work well.

It's just that you've already thrown some parts at it and your planning on changing a bunch more. Just buy a manual, it will pay for itself in the long run.

Hey, thank you for all the good info. I should’ve specified but I was referring to the cam position sensor in my original post. I will pull it apart and check that out. Good to know I’m not the only ones having a hard time finding stock ignition parts. I’m going to look into the Dyna stuff.

So, after much reading, and riding, I came to believe that it was not ignition but fuel.
Took the carb off, ordered the rebuild kit bought a ultrasonic cleaner, went through the carb. Reassembled and installed on the bike, and now it runs MUCH WORSE!
so frustrating!
basically it idles, but anytime I open the throttle it cuts out immediately.
Please help if you can. Any advice appreciated.
