I don't have a center stand and I see a mount hole on the Left side, but the closest on the Right side is used by that low mounted tank that sits behind the exhaust pipe.
Do you have to remove that tank mount in order to gain access to the center stand holes?
I assume all of our bikes have the mounts for a center stand even if they didn't come with one from the factory.
2nd question, is it safe to support the bike on the center stand using a bar and jackstands when you remove the rear tire, swing arm, etc... ?
3rd question, is there a special kind of lube for the swing arm? I have Mobil 1 Syn Wheel Bearing Grease, should that be good or should I buy something else?
Hmmm, we learn something everyday, I was not aware of that issue re the Right side.
If there is no straight line of site of adequate diameter, I would assume so, and Id assume it would be an easy do. (all of this is very suggestive that Evap can equipped 919s can't be fitted with a centre stand)
That is my clear understanding, only makes sense, and my guess is that there were way more centre stands retrofitted on a proportionate basis to Euro' 919s than NorAm 919s.
The centre stand is perfectly safe for such work. BUT simply using the centre stand mounting holes for a piece of rod slipped through then supported outboard by something like axle stands, is likely disaster waiting to happen. The diameter restricts the rod size one can use. Rod stiffness varies with the diameter to the 3rd power and length to the 4th power.
So supporting the skinny rod outboard means the 4th power factor will be dominant, and my guess is that it will bend - likely at the worst moment!
The factory centre stand pin diameter is plenty stiff for how the loads are applied to it in use.
In the past I have used an axle stand under the lean stand lug, then another under the side plate (that the swing arm pin slides through) on the right side. I've done it that way a couple of times, no problems, but be careful to make sure the bike is nice and square to the ground. I found it necessary to block up on side a bit with wood. Just be careful jigging it all up.
The issue is water, and being stationary, i.e not rotating.
I would not use a true synthetic lube, as it will likely be chemically neutral or to near neutral.
I would use either a lithium based grease, or anti-seize compound.
I honestly can't remember what I used, as I have both, I think I used the lithium grease I had on hand.
Speaking of true lithium greases, I'm finding it difficult to find it mass market auto departments nowadays.
I have to check further, but in the meantime I found a lithium grease doped with moly'di'.
That makes an excellent combination for a stationary swing arm pin that is expected to see moisture.
If the pin is anticipated to be R & R'd with any frequency, then the kind of grease used really won't matter much if at all.
But swing arm pins should be in place for many years, hence the concern over the lube selection.
Be sure to clean the pin tube in the frame real well before slipping in the lubed pin.
A piece of wood doweling with a wrap of fine emery or wet sanding paper works real well if any corrosion is found.
