Rocket running poorly, suggestions welcomed

I had a similar condition a few years back, ended up being a vacuum hose came off the Mass flow sensor attached to the intake plenum.

Definitely worth checking! This could cause all kinds of bizarre behavior. Easy to check all 4 hoses for cracks too with the K&Ns fitted instead of stock spaghetti.
 
Thanks Rob and all.

Update:
1. Walked a mile to get another plug socket.
2. Worker At NAPA informed me that there was a MC shop a mile away. K&G Cycles.
3. Dang the 2nd socket is too big.
4. Checked everything under the tank and buttoned it back up.
5. Reinstalled cleaned air temp sensor filter.
6. Called K&G and they said to bring it over.

Hoped on and rode to their shop without incident.
Hmm, did crimping the coil wire connectors or checking other connectors fix it or did I just not ride far enough?? TBD I guess.

They will install new plugs, check the battery voltage, adjust the clutch cable and see if they spot anything else first thing in the morning.

Unfortunately they do not have the Triumph diag tool and never heard on TuneECU.

The option to have Triumph of Pampano fetch me tomorrow still stands if the problem persists.

No sense in having a new TPS shipped here if they don’t have the capability to adjust it...
 
Fwiw, I just replaced my coils, "I think" I fixed a cutting out/dropping a cylinder problem I chased for 2 years, it was so intermittent that it took a while to figure out it only happened when hot, but I thought I fixed it 3 times previously. Just throwing it out there, if it's intermittent.
 
Vacuum lines are your problem on the 05 Rocket. 2 and 4 silicone is your line size on Amazon. Auto Zone will have your regular line that will get you back on the road. Replace the caps two you will more than likely have to put a screw in the end of the hose for the new caps on the carburetor.
