...in the area of for example the brake servo pipe or multiram vac lines affect the amount of vacuum that gets to the multirams and thus affect performance?

yes

yes
S'what I thought! Cheers mate :y

Changed another hose on the multiram system tonight.
1, Are the rubber hoses available? Various bits of pipe i had had an internal bore that was a bit big.
2, on checking the vacuum at idle at the ram actuators, i had about 14 hg. Is that about right?
(Marks guide doesn't state any measurements and im sure Mr bear would be interested)

Another thing to check is the vacuum reservoir to the left below the rams. I had the non return valve pack up and it wouldn't hold a vacuum.
Changed it and it made a world of difference to power and response. Pull the ram hose off the reservoir and it should hiss, or take the same hose
of the ram and put a vacuum gauge on. This will show immediately if its holding vacuum. Can't remember what the vacuum should be, but it's
listed somewhere, or somebody will come on and tell you. The important point is, is it holding vacuum.

The vacuum level dies quite quickly on turning off the engine..

interesting this threads rekindled from 2014 ??? ;D
if you pull off (top?) line going in to the vac box at the bottom of the bagpipes it should hiss. if it diesnt its a duff box and will need replacing. robg kindly sorted me out
but also check the vac box to the rear of the pollen filter. dead easy to get to and should also hiss when the correct vac line pulled after shut off.
lastly check the top hat seal (breather bridge to plenum) as ive had two literally disintegrate and also the two o rings from breatherbridge to throttle body. I used a snug duo from a Halfords set cos the OE ones were too thin and leaking vacuum. since I swapped them (ages ago) ivehad no vac leaks
