        @calum ive been through it more times I can count and never found any issues it's spotless and as for the settings I wouldn't have a clue I'm guess it's way lean on the a:f screw but it turns off on command when hot using the choke

          Sounds rich to me. Lean would cause a high hanging idle. The bike should still rev out, just without much power.

          When rich, everything is sluggish, and going WOT can feel like youre hitting a rev limiter, or as if the bike has a restriction.

          Have you done all the basics? Fresh plug and clean airfilter? Is your floathight correct?

            @jens-eskildsen that's a no on the float I've never really done that unless I really need to and if it's rich what do you reccomend a:f screw for move the float pin? Plug is good and filter is good no air leaks

              You could remove the side of the airbox and do a testrun and see if its better or worse.
              Dont think you can adjust the airscrew enough to sort this out.

                    @jens-eskildsen that's why I said I was trying to restrict air flow but made no difference

                      It's getting difficult.

                      When you start modifying stuff you're making it harder to diagnose the problem.

                      You really should only be modifying stuff when you know what you're doing.

                      If you're stuck, then I would revert it all back to stock and take it from there.

                          @declan Yeah, like I said. Get it all back to exactly how it should be. Then we can help to diagnose the fault.

                          It might be overshadowed by one of the many mods that have been done to the bike, hence why we are all struggling to come up with a single solution.

                          Or learn how jetting works. There is plenty of guidance on this forum for said information.
