    Something is definitely amiss. I've seen people on here get like 20K out the original piston. Someone claimed they have 40'000Km out of the original top end on here.

    From experience it tends to be running too lean that kills two strokes. Though a 2 stroke makes more power the leaner it runs. At 57mm you often have to modify the power valve for clearance. And the head gasket will need opening up. When the barrel 1st seized they might have replaced it with a 'good' second hand barrel that had already been taken out a few sizes.

            @gilerasc125 Are you using your phone to access this forum??? As that will cause problems uploading pics. 😉

                  @gilerasc125 That's why you can't upload any pics, as the forums software is buggy with mobile devices. Using a PC of some form is the best way to access this friendly forum. 😉

                    @NINJA I rarely have issues with this forum from a mobile device. What browser are you using? I always use Firefox and can use all the features just fine.

                    You should be able to request a desktop version from your mobile.

                    The website is written in Bootstrap CSS, meaning that really its the same code for desktop and mobile. So any bug that exists would be present in both systems.

                      @Calum Good_to_know, others have reported issues when using mobiles etc. So I was just going on what they have experienced.

                              @declan You did say exactly to be fair. If you didn't mean it then why did you say it.

                              I'm messing. That isn't my exact location.

                                  @declan Bike theft is everywhere in the UK No Exceptions.

                                  The law needs to come down hard on it in my opinion. It's disgraceful
