If I am not mistaken, you will need two kits for each caliper. Each caliper has four pistons. Someone correct me if I'm wrong. The fiche shows only one exploded caliper, but since you have two calipers, you need twice the number for a single caliper.
The 1985-1992 bikes have brakes with one pair of pistons, per caliper.

Thanks to every response to my brake caliper rebuild post . I'm 75 in age and own 2 gen 1 V max 1200's . the one I posted about is a 1993 . The other is a 1989 I wore out riding with over 100 K on the clock .I'm located in New Franklin , Ohio and apologize for my lack of computer internet skills which was all my wife's job until she went back to God 10-28-22. I don't know who loved the '89 more , her or me as whenever we hit V-boost she'd scream yeah ! can we do that again ? I miss the '89 and most of all I miss my wife who got so much pleasure riding Mr. Max & gave so much to me . Thanks again !

A real big thaks to Fire Medic for the great responce to my caliper rebuild questions & most of all for guiding me as how to navigate on the forum . Although I still don't quite understand all of it at least I now know enough to navigate better than I have so far . Gentsvmax advised not to spli the calipers . Any advice on why not ? and how do I rebuild them W/O spliting them ? Today I removed them but havn't bought the rebuild kits yet as life has it's way of slowing my production down when it comes to the things I enjoy most like my V max . Pre thnks too !
If you search the factory shop manual, you will not see any instructions for splitting the calipers. That is why gentsvmax did not want you to split them. Also, though it can be done, if it's done wrong, think of the consequences: loss of brakes, which can have very serious consequences. I will leave it to you to imagine the outcome of a worst-case scenario.
Yes, it will be more-difficult to clean any oxidation/corrosion from the bores, if you don't separate the halves. An experienced mechanic may approach the overhaul differently than an amateur would. You could ask at your local Yamaha dealer, "would you overhaul my brakes, and would it involve splitting the halves?" They probably would tell you, "we will not do a partial job!" You may find an independent shop which will overhaul your calipers.

Most caliper rebuild kits supply the two O rings that seal the two caliper halves. I have split several of this design caliper on my Vmax 1200, XJ900 and XJ750 and I did not find any problem doing so. Just make sure that male and female threads for the two M10 bolts are OK (and use Loctite), the new O rings seat properly and the mating surfaces are clean and all will be hunky dory. Torque not specified for bolts and that is where some experience is required. If I was asked to specify I would say use 5ft/lbs more than the generic value for an M10 bolt.
Yes it can be done. However, study the Yamaha dealer parts fiche and you do not see any o-ring shown for splitting the caliper halves. I checked K&L for their caliper rebuild kits and saw no o-rings included for caliper-splitting.
Not knowing about the OP's mechanical skills and expertise, any overhaul of the calipers should be left to a professional. I think that is a safe way to proceed. Have we done a caliper-split before? Many of us may-have, but there is an inherent risk in doing that. That's why dealerships and bike repair shops carry liability insurance. That is why I say, "err on the side of safety."

Here’s a kit right here…
https://brakecrafters.com/products/bc08s-1993-yamaha-vmax-1200-vmx1200
seems to have the orings for the caliper halves…..not sure what the big deal is…calipers are split everyday to rebuild …of course you have to be diligent but that applies to everything you do on these bikes.
standard qualifier applies of course…if you have the ability.

That is what I've suggested. Anyone here is able to work to the limits of their abilities. Something like a caliper full disassembly & re-build is not what I'd suggest a novice, or inexperienced in mechanics individual should undertake. Period. There is too-much at stake for someone who is prone to make a mistake in the mechanical repair of an essential part like a brake caliper, to undertake the repair on their own.
The solution is to find someone who is an experienced mechanic, who has the needed knowledge, skills, and abilities to do the work properly and safely. The owner can remove the calipers, and hand them to the mechanic, and get them back, ready to re-install (A suggestion here for using a reverse-bleed method to bleed the system quickly, completely, and properly).
Its not a big deal, cleanliness and getting them tight is all that matters.
I'm not offering advice, just saying that I chose to split mine and I didn't have any challenges.
My advice is contact Sean Morley and for pretty short money get one of his upgraded brake kits. The most noticeable in the saddle upgrade you can bolt on. (Not including nitrous of course lol)

I split my calipers to rebuild them and had no issues at all. I don’t know how you can completely rebuild/clean them without splitting them.
My calipers sat for 16 years before I got them. Yah got to split them to clean the crust. I also, used brake crafters parts. so far so good. 1K miles
