2015 F3-S jerking while riding

You are doing something wrong if the plugs had to be replaced at 8K miles. Ask your dealer what it is.

Hopefully the wires are in good shape.

Simply to clarify, OP says 2015 F3 with a 1330 powerplant, so no spark plug wires. COP style ignition.

My thoughts too. Possible but improbable. Fuel blockage has cleared at the same time would make more sense.

Had a similar experience with my 2015 F3s just a few weeks ago. Was just about to get on the interstate and what the hell, the bike began to jerk, backfire and had to keep the throttle moving so it wouldn't die on the way back home. I had only gone 1.5 miles when this happened. No previous indication of any rough idle or turning off on it's own. Service was due at 28K and the bike has 30K so wasn't too far out past the required service. First thing came to mind was to change the fuel filter. No difference, so next was the spark plugs, which is a lot of stuff to remove, tagged, labeled and bagged, so while in there I replaced the plugs from BajaRon, coils, the evap pre-filter along with cleaning and re-oiling the K&N air filter. NOW, THE MAIN REASON I HAD FOR THE JERKING, BACKFIRING AND HAVING DIFFICULTY IN KEEPING IT RUNNING AT IDLE WAS - - - - a FINGERTIGHT SPARK PLUG. It happened to my neighbor when his 2015 F3 had less than 2K miles on it. Runs like new again.

Had that style coil set up in a pickup once, and there was a replaceable wire in the boot. Didn't know if that was the same!!:dontknow: New technology, sometimes a PITA, for a dumb welder!!:2thumbs:

What's up with the 2015 F3 1330cc spark plugs?

jpbohmann -- 2015 F3-S 8K miles -- running on 2 cylinders; replaced spark plugs

juscuz -- 2015 F3-S 30K miles -- loose plug; replaced spark plugs and coils (also cleaned and re-oiled K&N air filter)

juscuz neighbor -- 2015 F3 2K miles -- unknown cause; replaced spark plugs

I picked it up and he said one of the plugs was bad and we didn't get into too much details with me about it. I questioned what I could be doing wrong, too high of RPM, gas, etc...? I don't know enough so I asked.
He told me nothing, one was just bad. He gave me the 3 bad ones in a bag.
RPM is steady and she is running great.
I bought it in 2022 with 1000 miles on it. Does sitting for years not being run do that? I ride normal, I don't run the RPMS too high or too low. I don't know ----- what I do know is it is riding VERY nice and enjoyed my ride into work today.
