About your mechanics……listen to your gut or your 6th sense. If you have a hinky feeling, it’s probably for a good reason.

With the dealer giving you those lame one liners as to what they've found, I'd grab my ride and leave.
I've been thinking about this "judder" you feel and the fact it seems to be mechanical. There have been a number of suggested solutions, all being the potential answer given the fact we haven't felt this "judder". I'd like to propose another. Could it be the clutch slipping slightly under hard acceleration. You purchased the bike used. I wonder what oil they used. An oil meant for cars has friction modifiers known to cause clutch slip. Grasping at straws here...
The other "solution" I came up with which was alluded to by another member, would be loose primary wires to the ignition coils causing misfires. Simply removing, then squeezing the push on connectors before reinstalling usually fixes the problem. I doubt this is the issue since you stated you had the bike on a dyno which should have picked it up.
Curious, when it was on the dyno, did they notice the "judder" issue during acceleration???

Hey
Hi Gregger,
It didnt feel like a clutch slip and I changed the oil 100 kms ago myself when I dropped the sump, I want to check the coils but I wonder if the shop will bother checking. If the head comes off they will have to. The dyno guy was very unhelpful and I think I waisted a $1000 there, the dyno sheet looks to consistent and doesnt show any issue other than only 120 hp

Originally you said, "jutter", which by definition is a, "beachcomber"., well, here in California anyway. Then someone said, "judder", meaning, "to shake violently". Can you be more descriptive about what you are feeling/hearing and when you feel it. I am somewhat able to relate to the word, "shudder", which is in the dictionary and means, " to tremble with fear". You feel the bike tremble? I hate being so picky but words matter and all these guys who want to help you need to be sure they really understand what you are talking about before their expertise can be accurately applied to your issue.
So, what exactly is happening when you shift between gears? So far I don't have a clue other than guessing what you might be feeling and/or hearing.
I went back to see what I am missing and I see you said in one post, " ...a judder or faint clunk...". A "clunk" is something I can relate to. My 2006 Classic exhibits a very, very slight clunk sound when shifting from neutral to 1st, gear. Same thing when I shift up through the gears but I do not hear it, I feel that in the heel of my boot when up-shifting or down shifting but it is almost imperceptible. The most pronounced clunk I ever hear is when I am maneuvering the bike in my garage with me on the bike and it is running and I hear and feel a very slight clunking sound, helmet on or off, in the drive shaft in first gear. Do you wear a helmet? I do and at 75 my hearing isn't great so I don't hear much other than the wind and the music I get through my helmet speakers. Sorry to ramble on.

Hi,
The Australian language is somewhat different to the American language in many subtle ways. The shudder/ vibration is after a gear change and when starting to wrap the power on in any gear then settles down once the torque drops off, sounds like clutch but just feels sharper than a slip. Once I get this valve leakage issue sorted and the coils have been re-installed after the heads put back on I will where we are at. It maybe worth changing the clutch just to eliminate it, why not this bike has been the mist expensive bike I have ever owned and I have only done 5000 kms on it. RIP my Thunderbird LT, it was by far a better bike until the accident.
Thanks for your time guys, I appreciate it

Ah, vibration, I know that word. Never felt any vibration in my Rocket other than that between the clutch and my drive train at zero speed maneuvering in my garage or parking lot. So, if your bike is vibrating when first applying power with every gear change, 2nd and up, then that should narrow the causes down for the experienced Rocketeers here. Thanks.
PS Do you have any accessories attached to the bike or loose fixings that might vibrate when the torque kicks in?

I remember back some years ago when another member (Alberta duke) was having similar symptoms . Seems to me it was a glitch in the Tune he was using. A more suitable tune took away the problem.

Just had another eureka moment... Is it possible you are feeling the affect of the rad shroud vibrating on the mounts due to the higher frequency when accelerating. Maybe the rad itself... I can't remember if you stated you only feel the vibes when moving under acceleration or when also reving the engine. These bolts do come loose, along with the exhaust manifold bolts and numerous others which cause undesirable noises and vibes...
Regarding the valve leakage... you stated the dealership has pulled the head??? Are they going to perform a valve job???? Really scares me. I don't think I have heard of anyone needing one. There have been numerous accounts of fellows not getting their valves adjusted resulting in tight valves which lead to leakage and valve damage (burnt valves/seats) but not with 10000 kilometers on the bike. That's only around 6000 miles??? I'm hoping they know what they are doing... Good luck.

Hey
I sent an email to Triumph Austrslia complaining about the dealer and the issue with the bike as it has only 10k on the clock and the head of warranty phoned me. He wants the bike bench run and the final drive checked, there is a spring in there that can break apparently. He doesnt believe there is a valve leak either.
