Misfiring

I have a 2013 GT with 8800 miles that seems to be running on 5 cylinders.

It happened abruptly while cruising at around 80 MPH. I thought I was running out of fuel at first because the gauge was near empty. One minute all was smooth, then it started misfiring. I have every reason to believe the plugs are original, but I am not blaming them because of the low mileage.

I have run some Liqui Moly Jectron fuel injector cleaner in the fuel tank, but that did not help. I don't have a 911 to read codes.

Has anyone got any idea what may be wrong?

oof a bike that old, coils seem like a likely issue. I ran on 5 cylinders for a while simply because I hadn't the luxury of paying a king's ransom to a dealer to do the work. Eventually, I found and ordered all the necessary tools for it, did the work myself.

@kakalika Does the check engine light come on and then maybe occasionally go off? Mine did that.

If it's noticeable enough that it runs legitimately rough and has trouble starting, you likely have one or more coil(s) failing.

I refer to that light as the master caution light, same as on a jet. Sometimes referred to as the oh sh-- light.

Without a diagnostic unit, you won't know which coil it is specifically. There might be ways of guessing, but why bother?

It could be many things, such as bad fuel, fuel pump or injectors........ but it still seems more likely to be a failed coil stick.

The bike needs hooking up to a dealer diagnostic or a GS911 to clarify.

is the misfire coincidental with speed / rpm / temperature / run time ?

I agree with the others that You probably have a bad coil. We don't know for sure until you read the codes. If it is a coil it's a complicated fix so if your not handy and your without tools you need to take it in so they can give you a proper diagnosis. I think the reason a coil or two goes bad is water intrusion.

I recently had a bad running/misfire with my 17 Bagger. It was only at low speed and there were no engine lights on. Took it to the dealers and importantly, there was nothing showing on the diagnostics, however there was clearly an issue. Half a days tinkering by them found a faulty ignition coil. That was replaced and all is sweet again.
