Thanhs for the replies, the cylinder I have is, I'm pretty sure the one you refer to, L/R part no 90569126, but it has different size ports. That said, if the end furthest away from the the push rod end is the resevoir, then I can use it. The old one off the S1 had the resevoir connected to the port in the middle of the cylinder, and I thought that the newer one would work the same way, I dont have a manual for a series II/III landy to check. However, i'm told that I could get a suitable adapter from a scuba diving shop, the UNF threads are used in diving kit, should I need to.

I'm converting the brakes on my S1 80 as I rebuild it. I am using 3/16 pipe and suitable cylinders, and have purchased a non-servo master cylinder for a series 3. This cylinder uses 2 sizes of brake pipe, 1/4 for the brake system and 3/16 for the reservoir, which I didnt expect, I thought it used 3/16 through out. Is there a master cylinder that uses 3/16 pipe for both, or can I get an inline adapter to convert the pipe size? I've done a search via google, not really come up with anything.

Chris, do you have an updated link to the video, this one is broke. An excellent wading video! Andy

I want to do the same, but not sure where on the gearbox the breathers are? Axles, flywheel and timing cover I can see, but the gearbox ones are not so obvious to me.
