- How many miles on the bike - out of warranty?
- Before the problem started were you flogging it (running really hard, redlining...)
- Will it still start?
- Send a video of it attempting to start and/or run.
That helps. I see the video now - last on your page of photos.
It's hard to tell anything definitive from cell phone audio, or maybe it's just my old ears. Doesn't sound right though.
The bike does run and idles (holds steady) properly.
Based on the p0068 code I'm guessing your throttle bodies are out of sync, linkage is sticky, and/or fuel filter issue.
When you did the compression test how did the plugs look?
Have you tried riding the bike? How does it perform?
You're coming up on the 20,000 mile service interval which includes replacing fuel and air filters, spark plugs, valve check, and timing and throttle body adjustments.
Did you or the dealer do the 10k mile service?
If you're able to pull the tank and do a compression test you can do the 20K service yourself.
Part 1 This includes valve clearance check and shim replacement. Also air, fuel, spark plug and coolant replacement, and bleeding the clutch. This is a work in progress, so edits and further information to come... Get the service manual here...
Just a side question for the OP, what's the small square box you've mounted near the clutch master cylinder? I also noticed you had the 3 keys on a key ring sitting on the seat, I hope you don't use the bike with the 3 keys together as Triumph says this could cause problems.
