    The athena head drops into the skull cap as a snug fit, then miraculously becomes a nightmare to remove 🤣 At least that was my experience.

    Cheers bud! That’s is actually very helpful!…

    OMG! I have fallen in love with Permatex Copper gasket spray! Why haven’t I found this before? It really is the mongrels dangles! Perfect application 😇

          Do the piston rings go a particular way on an Athena piston? I can’t see any difference between them. The only thing that might be a marking is a [ kind of shape, but horizontal. That’s only on one ring though…

            @SpookDog No? I just put them in so that the text was facing upwards and that the ring end gaps met the dowels in the piston grooves.

            Wossner are notorious for leaving one of the ring end gaps out of spec, gives the fitter flexibility to dial it in. The Athena ones I done recently were both spot on, but needless to say, you should check it against the spec.

                Don't chuck it on FFS! Amatuers! Place it on lovingly. Caress it, hold it, love it!

                Does look good though! I mean fair play to you and your workbench! You're doing it guerilla stylie.

                  Chuck is a term of affection from me! 🙂 Seriously! All new bearings and seals throughout, new Jamasil crank. I can’t afford to be ‘blasé’ 😳 I even removed, cleaned the threads, greased and re-inserted the barrel base studs and dowels to a tightness that they’re removable in the future, if needs be. The head studs I always remove and service…

                      The umbrella? 😜 …

                      Blaster 200 small end bearing didn’t fit. Was too wide to fit inside the piston. Luckily I had a dtr bearing that has wider roller/needles than the others I’ve got. Even with a bit of side to side play it still has good coverage of the conrods top eye width…

                      PS I just noticed that the Athena top end gasket set doesn’t include the orange PV bush seal! For nearly £50 you’d think they’d include it?!…

                        Just gonna replace the rear shock while the swingarm bolt is out. It doesn’t feel broken but it was crusty 30,000 miles ago. So, yeah! There is that…

                            To fit the small end bearing from the Blaster you need to file each side inside of the piston 0,5mm. To be on the safe side I removed 0,75mm from each side for when everything heats and diolates.

                                A little tip for people like me who have to ‘apply’ bearings with a hammer and ‘drift’ 🙂

                                alt text

                                Use a jubilee clip to hold in place whatever tool you are using, in my case a screwdriver…

                                alt text

                                Make sure it’s clear of the bearing, especially the race. It allows more of the force to be applied downwards, without worrying so much about slipping and destroying the roller~race. It makes the blows less ‘tentative’, more effective. It really makes a difference…

                                If you have a suitable tube then ignore me! 😉 …

                                        Just trying to muster energy to strip down for the new motor. Poor old frame hasn’t been tret well by three winters worth of road salt!…

                                        Fuxin surface rust everywhere. I dread to think of inside the tubing. I need to get it dipped and coated professionally this spring-summer…

                                        I’d like to have a different frame to work on really, If anyone knows of a usable frame for sale, please let me know. 👍

                                          @SpookDog I was thinking of getting another frame. I'd like to reshell my '05 into an '88 🤣 By 2028 it'll be MOT/Tax exempt 😛
