Someone pointed out that the cam chain tensioner plate, the thinner outer one, should be upside down. Does anyone know why. I don’t see an obvious advance.

I wonder if that's a MkIII thing. No rubber on the earlier tensioners, I believe.

I saw an earlier manual (with the magneto) and it said the plates were on the same.
What's right for a 'magneto' model isn't necessarily right for a Commando.
Factory pre-Mk3 manual, Clymer manual, Mick Hemmings in his video all say outer plate long end up.
As does the factory pre-Commando manual for 88, 99, 650 SS, Atlas, and G15Factory pre-Mk3 manual, Clymer manual, Mick Hemmings in his video all say outer plate long end up.
Pre-MkIII as in 850 or 750?
See Paragraph 10.
Then what is the manual that I linked to from? And do you see where it doesn't mention the plate orientation? Am I missing something?
Interesting side note I just discovered. The slipper/adjuster for the two chain engine and one chain engines are different. I never noticed this before. The orientation of the slot is different. Luckily, I didn't mix up the timing chest components of the P11's and '68 Commando with the later ones.
Pre-Mk3 manual is for all models "from 1970" (to 1973) and the manual you should have been referring to and not the '68-'69 manual.
Sorry to say it, but it sounds like you are trying to justify fitting the plate the wrong way up as the information IS in section C30, 7 of the appropriate manual.
More questioning the "why it makes a difference" aspect. I have my suspicions but would like to hear other people's opinions.
Well, I can only suggest you go back to my first (and second) reply as to why it makes a difference, however, that's just my opinion.
