Using the standard compression gauge, it would show you the highest reading of the 3 chambers. So if 4 bar is what you read, you need more than another way to test. Have you taken the exhaust manifold off, looked up into the exhaust port and pushed on the seals with something plastic or wood to see if they are free to move? they are spring loaded, make sure they are free to move.

Update: In the SAE Paper on the RE-5, there is mention of the Plating and the Apex Seals. The Apex Seals are listed as a proprietary product of "Ferrotic". There was/is a company by that name in New York state. I E-Mailed them and a week later there is still no reply. I will try again this week. I really don't expect them to have any just lying around but there may be a trail here (Hopefully a better result than my search for mag wheels awhile back...).

Good luck Charles, you never know.
Here is the gold standard...Have you taken the exhaust manifold off, looked up into the exhaust port and pushed on the seals with something plastic or wood to see if they are free to move? they are spring loaded, make sure they are free to move. Jeff
Be cautious what loostener/solvent you use to be compatible with the neoprene seals, if they are stuck, be patient and rotate rotor 1/3 (top backwards)to seal the solvent and let it soak. One more concern, don't use a solvent that will dry up harder and compound your situation before you can start the bike. Change oil again or very very soon as that muck is bound to end up in the oil. Please let us know how you are making out.

Good evening,
Thank you for all your help.
Sorry for the delay, i have a lot of work this end of year.
I find something (thanks to fonnyth).
I dismounted the exhausts and check the seal by the output of the gaz.
2 of the 3 seals were "glued" by the dirt. I deblocked them and find more compression but not a starting motor.
To answer to Timpa 136, i deblock the throttle gaz in the rotor. It's the butterfly mounted directly in the end of the carburator.
(Sorry for my technical english)
Thanks

One more thing, i used the WD 40 and the ACF 50 to deblock the seal

I thought that when they mentioned 'ferrotic' it was to do with the metallic (Fe) properties of the seals. They were based on cast iron with a few additives and a special heat/laser treated wiping edge.
The ever reliable and accurate (!) Wiki says: "Apex seals were made of a special material known as Ferro Tic, which was a combination of sintered ferrous alloy and titanium carbide.[38]"
To me, they look and feel like fairly ordinary cast iron. Magnetic, rust when wet etc. Only really know if I put a sample through the mass spectrometer. Don't have one of those in my shed!
To be a bit nerdy, the best coating or composition for our apex seals with current knowledge should be something like tungsten carbide or molybdenum disulphide. Norton motors use the latter in their internal coatings- not sure about their apex seals though.
A bit off topic, so good luck with the motor and getting enough compression to start! Sometimes a good squirt of oil into the motor followed by a tow start or hill start will get them running... but keep a close eye on the oil pressure light as you don't want to stuff the bearings!

Tchuss,
I had a set of running lights I used similar to those mounted on your bike. I think I have a brand new set as well, super bright , flat top beam cut off.
In the past I have warmed up the sparkplug with a few matches that seemed to help.

The ever reliable and accurate (!) Wiki says: "Apex seals were made of a special material known as Ferro Tic, which was a combination of sintered ferrous alloy and titanium carbide.[38]" That Wiki article is heavily referenced to source material. That particular citation refers to "Motorcyclist, January 1975, page 25". The article is a pretty extensive test. I quote from that magazine "...Suzuki employed a special material called Ferro-Tic, a combination of sintered ferrous alloy and titanium carbide...." So it's not really Wiki's fault, or the original author of that Wiki article. Presumably the journo writing that Motorcyclist article got his info from Suzuki source material and perhaps there's some chinese whispers going on. Don't believe everything you read, like the test on the GL1800 which waxed lyrical about the air assisted rear suspension which allowed you to go from zero to 25 psi. Other than the zero to 25, it's not even close. Or the RE5 magazine test that spoke of valves in the exhausts that controlled the flow of fresh air. People have been looking for those valves for 40 years. Or the superlatives laced through the early RE5 articles only to be replaced by decades of journalistic contempt. When you have direct experience with a an event that is subsequently reported in any media, you suddenly realise that the proportion of bollocks contained within can probably be generalized to almost everything you've read, heard or seen by reporters. But I'm off topic...........again What is it Andy, "Ferro Tic" or Ferrotic ? Cheers,

Don't tell Tim those valves don't exist. Those are fighting words.................

Hell...
I've been looking for those damn things for 40 years...
Leave it to Wayne to burst my bubble.

Oh, Furrow-tics ! Yeah, they mostly live on drop bears down here but occasionally they fall outta the trees into yer hair. Yer really don't want one in yer hair. On another note, ta Andy. Being another Aussie, you'd remember the Mitsubishi Starrion ? I always wondered what the original intention was when they thought up that name. Then it went to the Tokyo translation department before they made the brochures and name badges. Maybe aforementioned Motorcyclist journo got his factory blurb from the equivalent Suzuki department. So much fun reading Japanese owner's manuals from the sixties.
