Hello Guys,
I had been offered this wheel balancer stand : https://www.louis.de/en/artikel/rothewald-wheel-balancer-for-motorcycle-tyres-inclusive-axle/10009184?list=187899321&filter_article_number=10009184 because it was in sale.
I mount my tires myself. I used a pocket wheel balancer until now (two little plates fitted with two roller bearing each, the whole suspended from the ceiling) and I used the wheel axle with a tube as a spacer to suspend the wheel.
The nut at the end of the axle was torqued near the correct value in order to avoid any roller play and or wobble.
Now, I'm at lost. Because the wheel axle are too short to be used with this device.
If I use the two black threaded fixtures, I distort the whole contraption before reaching near the proper torque. And keeping the wheel centered is a challenge.
If I use the upper axle with the two conical support, I can't apply any pressure on the bearings so I'm left with some play into them.
What would you do if you had this device ? I'm puzzled...
Thanks for your advice.

Georges,
It usual to use the two conical supports centred in the bearings with only light hand pressure but then most wheel bearings are not spaced taper rollers like ours and will not need torquing up to remove all play.
If you need to use full torque to remove all play it might be your wedding band spacer too thick ? You could always remove it for the purpose of wheel balancing and put it back afterwards.

That is a very nice looking stand
You cant use the tapered cones unless you remove the top hat spacer.
If you are doing a bearing service at the time you change the tire Its not a big deal
This is what i use
No disassembly required
This is Special made just for the axle diameter

Yes, I've seen the Marc Parnes contraption, but they have two "problems" for me :
the locking screws are prone to make some unbalance
the ends are in ball bearings I already own.
Given the above advices, I'll remove the gasket and top hat spacers, or have an axle turned and tapped to be able to put the bearings under proper stress before balancing the wheel.

Wheel balancing.
I have never been a great believer in the various potions that can be put into tyres and tubes to hopefully seal punctures before all of the air escapes.
But such fluids do have a very interesting property - they dynamically balance the wheel.
I buy a bottle of [insert favorite magic potion tyre sealant here] sufficient to treat 4 car tyres and put half of the bottle into the front and half into the back wheel.
Viola! balanced wheels, and just maybe it might save me a puncture one day. The reason I use so much fluid is to provide the weight needed to balance the wheel.
Oh, and if following this idea, make sure your [insert favorite magic potion tyre sealant here] is water based - it helps with the cleanup and I suspect would be mandatory for tubeless tyres.

I stay in the closet on this issue because I am the only one this works for but I will open the door for just a second................ I have used "balancing beads" of one kind or another for years. The "Tire goop" would do the same thing if it would stay fluid and give the secondary benefit of sealing a puncture maybe.
The big question, is it still fluid and pliable to move around in a tire or is it formed into a solid un-moving coat inside the tire after a year or so? If it won't move it won't balance.

I was kind of curious how long the tire sealant would stay in a liquid state .
My bikes don't get as much use as they used to, so it's 7-8 years between tire changes on the R65's and Guzzi .
With temps here averaging 105 F for 6 months of the year, and tire temps in the 195 F, 95 C area during our ' hot ' season, I've been hesitant to use a liquid sealant in my tires .

The tyres I recently pulled off the wife's bike had been there since 2005, the tyre goop in the tubes was still liquid, however I threw them away as I felt expecting further service was pushing th boundaries a little too far.

I just locate them 180 deg apart

Put new Michelin Pilot Activ tires on a few weeks ago a the Metzelers were 20 years old and a trustworthy and lifelong experienced rider friend suggested I try DynaBeads balancing. He had it done to his '99 Harley Sportster and '69 BSA Rocket III and he swore by the process so I had them balanced with the DynaBeads.
Broke them in for a few dozen miles then did a 600 mile road trip over that weekend. No Problems! No bouncing, wobble, shimmy, skitter or anything to indicate the tires were out of balance. Never balanced tires that way before but I'm a happy camper and there is nothing on the outside to distract from the beauty of those wheels!
