I am on my second rocket. This one was new in April has now done 4500 miles and still there is a pronounced vibration at 4000 rpm. I never had this on my previous Rocket and this one is more vibey at anything over about 3200.
Triumph don't really want to know, and so their dealers don't either really. So I telephoned an ex-triumph dealer and managed to speak to their engineer who used to look after the Rockets.
He said when a bike did this, they used to slacken off all the engine bolts then retorque them up to spec.
So firstly - does this sound a plausible, and secondly are all the bolts reasonably accessible (how many are there?). I have a list of the torque settings.

I have heard this recomendeded many times over the years on other bikes. I'd certainly try it. Maybe there's even a correct order to torque them.
Throttle body synch might help too.
I'll bet Warp knows for sure the sequence and the torque, not to mention the number of bolts.
He can probably rattle it off right out of his head for you.
sounds reasonable,
I know if you install the crash bars and don't get the bolts just right,
she'll shimmy.
First balance the throttle bodies. The dealer might say that it idles okay, but they still may be off. It is easy enough to check and correct with either TuneBoy or TuneECU.
The engine mount bolts need to be tightened in a particular sequence. The manual has the info you will need. However, to do this correctly you will need some special Triumph tools for the castle nuts. It would probably be cheaper to pay the dealer to do it than buy the tools.
I agree re torqueing the engine mounts in the proper sequence might just help. You can knock the lock spanners loose with a brass punch. Or make some of the special sockets from a SAE socket. I believe Ruzzle had some pictures of the one he did. I would support the motor and lossen all of them and then torque in the right order per manual.
thanks Warp - as it happens that's what the dealer is going to do tomorrow.
IDK - am I understanding you correctly -I realise that TuneEcu can check the throttle body balance, bit can it 'correct' it?
Thanks
Mike
