    @2stroketerry I’m surprised you lot like the o rings I hate them with a passion I love the simple metal one like dt has I’m always having leaks and such from poorly fitted o rings even though I try my best to fit them perfectly

      @declan That's your problem then isn't it. Poorly fitted.

      I've not had issues with O-Ring gaskets. Usually a dab of grease to hold it in situ is enough to sort any problems out if you're having them.

        @Calum none of that worked for me they wouldn’t sit still the last one I did I used the lightest amount of super glue just enough to keep it in the groove and that worked any other time and it would always slip out an pinch the ring I should add this is on the cheap replica rs cylinders so the machining wasn’t exactly flawless

          @declan using glue is the last thing you want on an O-ring just a bit of silicone grease, but having a poorly machined groove the O-ring sits in probably doesn't help.
          Yamaha use an O-ring on there best 125 cylinders the SP although don't actualy make that cylinder themselves.

            I seem to remember someone once said that applying a bit of petroleum jelly, aka the good ole Vaseline works wonders for keeping your 'O' ring in good order.

                      Like with most things, the work is in the preparation.
