Default Misfiringt
I have a 98 Road King garage kept with 4K miles on it, while riding with engine underload it feels as if I am turning the ignition switch on and off, pop back fire etc. Removed ignition switch, clean inspected and reassembled and no change. Spring tensions check out, can't figure it out, any thoughts?

Carbed or EFI? Checked the plugs? Intake leak?

Only 4,000 on a 98? You need to ride it more

I had a fuel regulator fail on my 05 Nightrain that gave similar symptoms. It would stumble only once and a while and backfire real bad on decel. It would still start and run just fine and it was intermitten.

Good luck.
