I'm going to be fitting a carberry vibration plate and upping the drive sprocket one tooth on  21 classic 500.  The bike is reasonably smooth as it is,  however this plate is for longevity of the crank.  A larger portion of my riding is in the 80 to 100 kph range, before I can get onto the back roads and plod along. Could I ask anybody whose fitted a plate if they really noticed any difference in vibes.
Drink now....avoid the Xmas rush.

I fitted Carberry plate to my 2018 C5 and fitted a 1 tooth bigger sprocket. I noticed marginal improvements on vibrations. The biggest help to quell vibrations was fitting a double heavy duty heady steady.

It's good to see the old Carberry Plate for UCEs being discussed once again. All our old models seem to have fallen somewhat into the silent shadows of the loud new kids on the block, the 650 twins, 350 Meteors and their ilk. 

A few years back our esteemed member 'Brad the Maddman' did a lovely YouTube look at that Carberry plate from unboxing and close examination through step-by-step installation and a verdict on its effectiveness in reduction of vibration here: https://youtu.be/SLnhYPl3_Cs. If you're unfamiliar with his channel, it's worth a good rummaging and binge through his back catalog. The Maddman did a lot of great product reviews of stuff, both of particular interest to UCE owners and other models besides. You can also watch him gamboling through the woods like some lethal Pilgrim with his homemade blunderbuss. A man after my own heart, he also coordinated that "Royal Ramble" Enfield gathering in Galax, Virginia so cursed by the weather gods and monsoon-swept that ALL of the attendees to brave the trek arrived without exception in green "Military" trim Bullets, the owners of all other hues presumably being either too sensible or pantywaisted to brave the elements. Like I said then in a fresh take on the Marines slogan, "The few, the brave, the stupid." But the weather wasn't Brad's fault.

Regarding vibration reduction, there's also the "folksy" but often effective technique I recently described here: https://forum.classicmotorworks.com/index.php?topic=32894.msg407887#msg407887

So badass my Enfield's actually illegal  in India. Yet it squeaks by here in Virginia.

This is something l toyed with but the reality is my bike hardly vibrates so l decided to shelve the idea l was lucky l seemed to have got a good one that doesn’t shake.

Onle a few seem to be unlucky and have bad problems. Some vibes are to be expected.

Yeah, my hunch is that by now any REALLY unpleasantly rattly Bullets as a result of slapdash engine mounting have likely either vibed themselves into some sort of equilibrium or out of service. But with his mentioning of that Carberry doodad, I thought that relatively simple and quick technique bore a mention anyhow. Of course, there were other common enough causes for excessive vibration, such as poorly-balanced cranks, I'm told. But better centering those engine mounts were an easy fix. Still, if you're happy, there's likely no problem there to fix.
