Syncing Throttle Bodies- Stelvio 8V

Glad you found the guide informative! Thanks.

The balance at running speed is far more important that idle. If you are out of balance (and I mean substantively i.e. > 1.5cm mercury) then this will indicate that the engine is fighting against itself.

Most people think a small 1/2 cm variance is being off. It's not. Anything within 1.5cm is considered "the same".

Like John above, I focus more on the running speed balance and it is imperative that both air bleeds be closed before beginning any of this. You only open the one side with the highest vacuum, to bring it back in line.

I think you are over thinking this.

Also, you will never eliminate handlebar vibration this way. The bar vibrates because it is hollow. There is no way around this. Also, you are death gripping the bar. Focus on relaxing your grip and not laying your weight on the handlebars, and this will dramatically decrease in my experience.
 
Re handlebar VIBRATION: I noticed a quantum difference on my 2017 Stelvio compared to both my 2013 and 2012, namely the frequency of the vibration feels much higher, causing very uncomfortable tingling in my wrists and hands. I have no idea why I feel this difference but it is VERY noticeable. I added handlebar risers (eBay) and use polyurethane foam sleeves on the handles (lots of arthritis) which helps.
 
Thanks all - appreciated, and Scott you pretty much hit the nail on the head wrt over-thinking; it’s certainly not the first time. I simply like to get to grips with stuff. Can’t agree to the death grip suggestion though, this Griso is the only bike that has / does give me such issues; can’t even blame it on a V-twin as can ride my mate’s HD with no such issues. It’s as Nicolai describes, my wrists must resonate in sympathy with the buzzing h’bars! Ouch.
The grips (PO installed) are heated Oxford units, with no fat in ‘em. Next port of call might be to swap these for something meatier & a bit more pensioner friendly.

You could try grip puppies. They go over the existing grip for higher diameter and cushioning.
 
Cheers John, though today I took off the Oxford Heated grips and replaced them with stock Griso grips which amazingly I had squirrelled away for some obscure reason. If this (free) experiment fails your suggestion follows…
