I noticed my sons XR650L has a vibration dampener fitted between the mirror stem and the the handle bar mount. It looks to be an add-on by the previous owner. Has anyone tried this on the stock SCR mirrors to see if it helps cut down the vibration / distortion?

The 89' XL600V Transalps I had came with those dampeners on identical/nearly identical mirrors.
To see if the XR's came that way, check and see if the mirror stalk's thread diameter isn't smaller than the mirror mount holes in the bar clamps.
That is to say one cannot unscrew the mirrors, remove the dampeners and simply mount the mirrors directly. They won't fit.

The bad news is one can't just get a set of Honda dampeners even if they were the same diameter.
The right side Yamaha mirror has reverse (LH) threads.
=(

You are correct, again. It is a Honda part listed for that application.
What is your opinion on the ability of that little rubber insulated mount?
Do you think it would help much if one could acquire a properly sized item for the SCR stock mirror?

I'm not sure it'd work to the point the mirrors wouldn't still shake to a blur at most speeds. Couldn't hurt to try, if the price wasn't too out there.
I had high hopes that adding a set of SV650 bar end weights would sufficiently quell the vibes on my SCR. Those hopes got shaken free and are still lying by the roadside after the maiden ride following the two hours spent installing the weights. The weights look okay, though. ;-)

I can vouch that the combination of Renthal bars and decent (read ‘heavy’) bar-end mirrors has reduced vibration considerably, and the mirrors are now usable over a much wider range of revs. Whether this is down to the bars, the mirrors, or combination of both, I couldn’t tell you.....my feeling is the alloy bars on their own are responsible for a lot of the vibration-dampening (I never tried the regular mirrors with the Renthals). Depends how far you wanna go to solve it, I guess......

I had similar hopes when I added some mass to my bars in the form of handguards. Wasn't enough I guess.

Slight tangent (sorry), I once spoke with one of the designers of the original Keurig coffeemakers who told me their early prototypes would vibrate quite a bit, and the quick-easy-and-cheap solution was to bolt a hunk of steel to the inner frame. I really wish Yamaha had thrown a bigger slug into our bars. And threaded it :|

Thinking about it a bit more with the Renthals - if they didn’t quell the vibes enough on their own, at least you could then also add some bar-end weights too (given they are open-ended), without having to resort to what @eddie did.

It was a venture into the unknown for me and the bar end weights.
Now that I've done one, it's an hour job, maybe.
Carefully cut the end of the grips off, drill and tap 1/4"X20 holes in each end of the bar, install the SV650 weights with 1/4"X20 stainless bolts from the hardware store with a touch of Loctite and ride. =)
I later added some Progrip 714 gel grips and sanded the cut ends tapered down to meet the weights to complete things.

There is another way. On my old Concours (which was the absolute worst vibration I've ever felt on two wheels!), there were folks who used something called a bar snake, which I believe is no longer available. But the poorer mans version is ... lead shot. Get the smallest you can get and fill the bars up. It actually works pretty well, assuming the bars you use have open ends to get the shot in. Just fill it up and the shot vibrates taking the resonance out a bit. Some bar end weights and viola.

They do make weights that simply toque down with a bolt, but I've found they don't stay torqued down long. Agree with the loctite. Use red.

Haven’t I seen you mention elsewhere that they’ve not actually done that much for the vibration issue though?

If they did help, I can't tell it!
It was an exercise in futility.
It also kept me busy and off eBay for a while.
Sort of like the day I drilled the brake levers for aesthetics.
LOL

They look ok, and have you seen the price of the official Rizoma ones??! Oooff!! :|
Ben

Bought the Suzuki ones listed here and then actually found a set in my tool box from when I put a pair of Napoleon bar end mirrors on a former SV and forgot about the factory weights. Doh!
For the price, they are really nice, even if one cannot used the bolts with the stock SCR bars.
