Hi
Just to show one way of putting in new diaphragm , I ordered types like the original, so you need a rubber ring and clip (seegerring) to hold the new part, when you cut of the original plastic retainer...
See pics, got a few banks of carbs from the scrapyards, to clean and sell on, costing between 30 and 50 dollar per bank...

I hope, this one does :Facepalm:
Nope, no pictures.
Are you sure, on the UK website it seems to work...
I can see them
I can see them from the second link.

I can see from the second. He is Using a large circlip to hold the diaphragm in place.
Yep, my bad...2nd link works...
Here's what the pictures look like.
I recall several years ago RPM Randy tried some aftermarket diaphragms only to find that under full throttle (full vacuum) the carb slides did not raise all the way up. The thicker, less pliable material was the reason.
It would be interesting to see how these performed. You would need to put the bike on a load Dyno and look at the slides under full throttle.
Hi
The diaphragms used are very light and feel the same as the original, 5,1 gram, as soon as I've put all of them in, I will test them, NOT on a Dyno, I hate that...but on the German Autobahn and see what it does.
Cheers, Tom.

Tom, what brand of membrane did you obtain?
I did some testing on the JBM replacements in Garth's carbs many years ago. I found they did not have the same stroke as the original and would not allow the needle to lift fully. The lack of travel put the bike in a lean condition at 3/4 to wide open throttle. The full topic is is over in the carb files: http://www.fjowners.com/index.php?topic=5340.0 (http://www.fjowners.com/index.php?topic=5340.0)
Here is photo of what I am referring too

Hi Randy
I could not find a name, I will ask supplier, but they are very similar to the originals, travel is the same, I will check how my FJ goes as soon as they are all done, waiting for Viton flat washers to put under the clip to hold the thing in place....
Cheers, Tom.
