    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

              @vtrn_raptor so it does start without choke? I can't make sense of what you said mate.

              If it starts from cold without choke then it's 100% too rich

                        @vtrn_raptor Yeah that's normal mate.

                        It needs choke to start. That's normal. My DT NEVER started without choke.

                        Once it's warm you can take the choke off that's normal.

                        It must be something to do with the stock carb, as I haven't had this issue with my VHSA.

                        But yes, it will need choke to start. Then once its warm it'll go to die, you then take the choke off.

                        What's the problem.

                            I mean it goes to die before it's warm to keep it going I have to keep the throttle on but anyway just took for a little test ride without the snorkel and was a massive improvement but powervalve still won't kick it it goes to then starts to bog but stays running and it's actually rideable

                                        I'm gunna take the pv cover of and rev it to see if it opens correctly as that could be the issue as was pinned before I got the cdi and put it back on the servo
