    @OllieDTR The 170 kit is ace 😉

    Works really well on my setup and it's made the bike a lot more enjoyable to ride IMO.

      Mother Nature isn’t so bad, it’s the local council and their grit lorries! 😉 …

      Fair play, it was black when first registered, just with a red frame…

      Getting the rack fitted nicely took a lot more than it should!…

      PS I don’t have any smiley face emoji’s showing up, is that an iPhone compatibility thing?…

          Pissing coolant from the bottom of the barrel, where the casings meet. They’re not a matched pair and one is a hair higher at the front on the clutch side. Perfect at the back…

          Going to lap the front with wet and dry and a 10cm (10cm X 10cm) square of plate glass…
          It was the one time I never used sealant on the base gasket, plus I used my Vertex gasket on the Tzr! I ended up using one of those 0.5mm fleabay ones. A decent thickness gasket and copper spray sealant and I’d probably never had a problem…

              Don't forget to file the inside of the piston as I've mentioned on another post.

                  File each side of the piston,the bearing must drop and have a little play.
                  I believe 0,5mm or 0,75mm of each side will do,measure your bearing because they are not all the same.

                    Why thank you Sir!…

                    I did get round to doing some things today, once I stopped feeling sorry for myself:

                    alt text

                    Lapped it smooth and ‘all over’ even as I could with what I have to hand…

                    alt text

                    I always hate putting on a top end with the engine in-frame, but what can you do?
                    March or die! Can’t give up either way…

                    I had to remove the side cover and rotor so I could remove the stator, all so I could replace and tighten the coolant pipe-mount/engine-bolt! I did manage to torque up the stator nut this time because I could lock the crank via the little/small end…

                    🤞

                      I forgot to ask: Does the Athena kit give the kickstart a more ‘compression’ feel than the standard? I used to be able to turn it over by hand on the kickstart…

                          Yeah, I did wonder…

                          I’m going to leave it overnight for the leak-down test, before I start throwing it back together again. It’s dry so far…

                            Yes it does. The first time I tried to start the engine it kicked back like a 4T and did little damage to my ankle. I had tha face "what the fux it's my XT600 all over again".
                            After the run in km's never happened.

                            Your spark plug wire must go from the other side,if you follow Yamaha schematics.

                              The high tension lead? Interesting. I guess all my loom and wiring is bass ackwards! 😜 …

                              I had a 400 single that you had to find the sweet spot on, or it’d try and break your ankle! It had a decompression valve/lever that I could never get on with. You got to love 4/ singles. It’s like riding a 2 wheel tractor 🙂 …

                                Looking good spook! Have to let us know what the 170 kit is like and jetting wise. I’ve got to Abit of time to order mine be good to see how it goes with the TM32mm carb, are you running stock oil pump? I have the newer oil pump setup so can adjust it more be good to see if anyone has a guide on how much it needs adjusting by

                                I’m going to be running the standard pump to match the standard 28mm carb…

                                ——————-

                                I think you need to work out the cm2 of the 28mm carb. Then the cm2 of 32mm. Figure out the % increase of the two. Then increase oil at WOT by the same %…

                                Or does that sound like BS?…

                                      Yeah I know, I live a very sedentary life. I get bored easily 😉 …

                                        Went for a test ride, it was OK but getting misfires/knocking at certain lower revs. That and it was taking a bit of effort to tick over cold…
                                        First thought was check the plug. It looks sweet. Looked to the right at the carb thinking it might be an air leak and remembered I’d changed the rubber inlet manifold. I forgot to blank off the 2T oil pipe inlet! What a twat?!….
                                        🫤

                                        Gonna test it tomorrow with the oil pipe blanked off!…

                                          Oh, that's a shame. Hopefully all sorted now.

                                          Took me a little while to get the jetting right on my 170 kit, but now it's done it's lovely.
