I have a 97 dyna convt with 20k miles. The issue I am having is that somewhere close to 3000 RPM in 4th or 5th gear at highway speeds it is losing power and then cuts out and sputters. If you roll on the throttle it makes it worse if you let off the throttle it takes it a bit but it comes back and runs ok until you get back close to 3k rpm. Sometimes if you downshift to 4th it will run ok sometimes not. This issue does not happen consistently however which is why i am so perplexed. If it happened every time I could trouble shoot it easier. Some days it runs perfect other days it will start off good and then start acting up. It seems to have some coloration to when I shut off the bike and restart it. IE It ran great for 200+ miles and 2 gas stops then I stopped to take in some sites and as soon as I got up to 60+ Mph and 3000RPM the problem started again. I have changed nothing on the bike in the 10k miles since I bought it and it has only had this issue for the last 3k or so. Bike is stock except for Screaming Eagle air cleaner and cover, Exaust has been opened up, I know it has been re-jetted but dont recall the size. The tune seems good and plugs look good as well and have been changed. I have replaced the plug wires and drained all fuel and cleaned the carb. My first thought was bad gas or dirty carb but everything looked good and it does not explain how random this issue occurs. Once it starts acting up it will not come out of it unless you shut it off and that only works sometimes. All wires and connections look good and tight. I am not good at electrical troubleshooting so that is why I have not checked into that aspect of it yet.
I have been told it looks like the ignition is starting to fail but figured I would see if anyone on here has any other ideas or a similar experience. I have looked through a ton of posts and have not found any experiences that quite fit what I am experiencing with this bike. Any thoughts are appreciated.
Thanks
