momentary loss of power when accelerating
Hello all! 91 FLSTF, about 55k miles.
No Tach, but when I'm accelerating(usually 3rd through 4th gear), when I'm in about the same RPM range it feels, I get the SHORTEST blip in power, if I'm really on the throttle when it happens, my exhaust backfires LOUDLY.
When it happens it's like a fraction of a second.
Electrical? Fuel related?
Any ideas?

UPDATE:
Pretty dang sure my issue is related to moisture in the air/humidity.
The first time it happened it was literally RIGHT after a full 2 weeks of non stop rain.
It just happened again this morning(while raining).
Does that help at all? Any more ideas?

This may be pickin' the flyshyt outa the pepper, but I don't think it's so much *related* to humidity as *exacerbated* by it, if anthing at all.
I'd suspect coils or wires.

hehe. Y'all might be right. I pulled my wires about a week ago, inspected, and re-connected..haven't had the issue since(knock on wood!)
Thanks again, everyone.

You have got some good replies..
One of them is probably the cause. My thoughts are the valves are floating. not having time to completely close. would hesitate ever so slightly. Just my opinion.

Springer's valve float comment has merit as well. A weak or broken spring?
