    Brakes on my DTR were horrendous.

    Don't have that problem any more, bike stops on a DIME!

        @SpookDog It's definitely bled properly?

          @Calum

          I don’t think that it is. There’s no play on the lever, let alone sponginess, but I don’t think it’s getting the full pressure of the system at the pads. I can’t see any other reason…

          47,125 miles today! That’s 34K since I’ve been riding 🙂…

            @SpookDog Mate, that's a mental amount of riding!

              @SpookDog In practice the linkage bearing sleeves often don't wear so if you vernier your originals up and they're still close to 20mm OD you can just get the linkage parts separately. Relay arm bearings:

              https://shop.marksman-ind.com/93315-32052-00-equivalent-yamaha-bearing-29446-p.asp

              Linkage bushes:
              https://simplybearings.co.uk/shop/p142950/MB2020X-Bronze-Backed-Steel-Bush-20x23x20mm/product_info.html

              Seals:

              Double check all of these dimensions before ordering as it's a while since I did a DTR linkage job but I'm pretty sure these are correct. Just rip the piss out of me if they're not.

              Is there anyone who knows the sizes of the needle-roller bearings and the phosphor bronze bushes definitely? The only way I can find out is to strip down the linkage first. I don’t want to take the bike off of the road though. Also I’ll probably destroy the bearings and bushes during removal! From what I remember the bearings were loose rollers that I had to stick/pack into place with grease, only the outer ‘cages’ were drift~fitted inside the linkage to frame union. They were very thin gauge metal and easily damaged…

              Ta!…

              PS. Is the 20mm inner or outer?…

              Edit: The inner is 20mm on both bearings and bushes. Are the bearings 23mm outer like the bushes?…

                Well, I couldn’t confirm the sizes, so I’m hoping that they’re right so I don’t have to Rip t Piss out of Hotshot!! 😜
                I’m just praying that the sleeves are in good enough order (especially the roller bearing one) to match up nicely 🤞 …

                  Stopped riding for about six months cause of old git health problems, only just renewed my CBT again!
                  Took me over a year to fit the new bearings and bushes into the rear suspension linkage! Didn’t realise how big of a faff it was going to be to get them pressed in straight and to the depth that’s needed for the seals! Done though. Nice and tight on the ass end! No more ‘snatchy chain’ feel when pulling away 🙂

                  Is HotShot still around? I need some info on wheel builders in Dorset. I can’t find the old post recommending a particular one. My back wheel is a bit up and down, as well as being a bit side to side…

                  Unless anyone has a decent straight rear wheel for sale?…
                  Ta!…

                    Oh hey blast from the past!

                    Yeah @HOTSHOT-III is still knocking about.

                    Sorry to hear about your health problems, considering how much you use your DT that's a crying shame.

                      @SpookDog Hey bud, hope you're feeling better. I did wonder what had happened to you.

                      Good to hear you've sorted the rear suspension 👍

                        Still going well mechanically, just looks like a dog 🐾

                        Cheers for the link bud!…

                        I really need some hubs if anyone knows of any for sale? Back one is way more urgent than the front!

                        Only issue is it seems to be running a bit hot. I removed the plastic cover from the radiator and it was an improvement, but not great. I’m wondering if being stood up and hardly ridden since last winter has let the radiator clog up? The radiator was well hot when I checked it. Like it’s not shedding the heat. The ‘fins’ look clear, so I’m wondering if it’s an internal obstruction?
