    Could be a conflict between old generators and new CDI's (for example) but with that amount of money being spent on it chances are its now something relatively simple

    I do however appreciate how frustrating these problems can be at time and how you want to murder someone when you've taken a carb apart 58 times 😉

          @vtrn_raptor Sounds like it's running rich. Is it sooty? Could be too much oil.

          Two strokes don't have too much compression.

              @vtrn_raptor really start from scratch your only confusing your self more it does sound like your running rich like @Calum said but I would not say that as you have still not put a picture of the plug up or taken a video and it could and most likely is too much fuel and that's why I said to run the bike for 10 sec's and take a picture as your descriptions are bad but considering that your at least trying I will tell and show you the differents alt text

                    the top one is a plug with too much oil
                    the bottom one is too much fuel

                    which one is your closest too

                                  Will it start without choke?

                                      That looks and sounds like it's overfueling to fook.

                                      Quick check, remove the snorkel, does it get better or worse. Restrict the airbox, does it get better.

                                          Idles fine until giving throttle will gradually build up to 6k and even past it but does what happens in the vid if you give it full throttle with choke on it dies instantly but will start with it on but have to turn it off usually starts first kick from cold I'll take the snorkel off in a sec and give it a go
