I have a 2016 cct with 83k miles, I pushed the bike out of the garage and it ran like crap, pulled the plugs and the rear plug was black and the front plug was clean as a whistle. I put some sea foam in it and ran it thinking I may have a dirty injector, still runs like crap and I now have a light on in the dash. How do I get the codes?

When you last started the bike, did you take it for a ride or just run it for a few minutes and shut it off?

What performance mods does it have?

I just ran it for a few minutes and it idled fine. The next day I was going to go for a ride and it ran like crap from the start. I road it 1000 miles the weekend before

I bought the bike new in2016 and had a stage 1 installed also has a lloydz timing gear

Agree with @BBob about checking compression, think I would do that first.

90 lbs on front cylinder and 119 on rear

I checked Bob's down load and I saw nothing on the cross country tour. Thanks anyway

Replace your spark plugs after regapping the new ones, when is last time cleaned air filter & cleaned tightened battery cables

Yesterday

Install a new set of plugs, probably all it needs.

If you start your bike, take it for a ride.

Installed new plugs yesterday gap at 32

There are issues such as poor grounds and bad ignition signal that could be involved in what you describe as well.
So don’t throw parts at your bike. Start with checking the battery connection on the frame, starter relay, engine etc.
swap plugs front to back AFTER CLEANING the rear plug and see if the rear still is black if it will run well enough.
I would not ride it if it runs too poorly. Not worth damaging anything.

on consideration I would look at how to test the O2 sensors? Are they original? If not are they wide band O2 sensors?

I have swapped plugs with the same results, just checked the battery connection and they were good. 02 sensors are original. I had something similar happen a few years ago in the mountains in Colorado. Shut it off and when I restarted it, it ran fine never to bother again.

These guys are right. Always do the easier checks first. The 29 lb difference between cylinders is concerning but doing a wet warm comparison would be closer to how it is when it's running.

Possibly a weak coil or bad injector would be on the list of things to check first.

When I had the coils out I checked from the outside prongs to the center and have cotinouty I've checked the wires and have 4.8 ohm and 5.4 ohm I don't know how to check the injectors. I'm going to order new injectors.

Okay, here is how I (after resetting TPS etc) would check the injectors; Disconnect the coils, Take the rear injector loose and find a way to put it in a container to catch fuel.
Probably best to do this in a safe area like outside. You may need a second person for this potentially sketchy project. Then turn the ignition on. At that point there is usually a push from the fuel pump.

Watch for dripping from the injector. It should not leak. Then if no leaking is observed engage the starter while watching the spray pattern. Engage the starter for an exact time such as 6 seconds. Look at how much fuel is in the container.
Do the same with the front injector. Compare them as they should be the same.
Yeah, not perfect and if you are not careful to disconnect the ignition coils it could be a lot of messing around with limited intel. That said the resulting conflagration would be something you could tell your buddies at the local watering hole in ten years or so after the trauma fades in your memory.

So under no circumstances do you do this without disconnecting the coils!!

Thanks I'll try this, looks like it's a chore to get the injectors out.

TPS? Are you referring to the computer

 

[tezinsma]

Did you download the service manual from BBobs mediafire?

TPS - throttle position sensor.

there is a specific procedure for resetting both the TPS and IAC. Quick and easy place to start

I have gone to Boba down load and can't find the service manual for my cct 2016

 

[tezinsma]

I see quazi already linked it for you, but my screenshot was straight from Bobs list.
Hopefully you have it now.

I do, thank you so much for your help!

 

[tezinsma]

Please update us on what you find.

I will... thanks again I have a fuel filter ordered

Replaced the fuel filter and ran a fuel pressure test, 51 psi pressure. Taking it for a ride in my trailer to the Vic shop in Iowa and haveing the hole bike gone over maybe a rebuild.
