I'm in the US, but sprung for the extra money (which was not really much) to order new seat foam and covers from Leighton. I ordered for both my '66 restoration project and for my regular rider, a '76 T140V. The 140 seat was original and after a half hour was worse than bleecher-butt if anyone here has spent time watching highschool basketball games.
I was very pleased with the foam for both bikes. You can see the finished seat in my restoration thread and I believe I posted about my 140 seat in the general forum. Leighton disappointed me on the cover for the 140. The cover they make for the 140 uses the top from another year and the result is the stitching does not fall into the molded in groove when used on a '76 and to me, it just does not look right. Quality was top notch, otherwise. I ended up getting a cover at a swap meet that came from John Healy and it fit like a glove and was correct for my year.
So, make sure if you are buying a cover from Andrew, that he confirms it will be correct and identical to your OEM cover. Otherwise, I highly recommend his products.
Suspension-wise, there is another thread hear that askes if cartridge emulators can be used in late model forks and the answer was yes. Emulators do a lot to improve the range of a front fork. The problem with damper rod forks is they use fixed orifices as part of the design. That's fine until you get on a rough road or series of bad bumps. I can't remember my fluid dynamics that well, but the pressure across an orifice is something like the square of the flow. So what that means is when you hit a big bump, the fork becomes a solid piece of pipe. Emulators have a disc valve with a spring controlling it's ability to relieve with high pressure. So you get good damping under normal road conditions and when you hit that mutha speed bump or get on a road that is really rough, the cartridge comes into play and your rider is much more pliable. So, spending whatever they cost in the UK for emulators, is probably worth it if you have one bike and ride it long distances.
Regarding your rack, I wished you lived in the US. I have a 6 pack rack on my 140 that I'd gladly trade for a passenger grap rail in the same (excellent) condition.
I have one more trick for you for long distance riding. Go to a bicycle store and by a high quality pair of bike shorts. These are spandex shorts with a pad in the butt area. I wear a pair for the 3 day Motorgiro that I ride with vintage Japanese bikes and those shorts make a major improvement in comfort.
