    Well I've took the servo and everything off made sure wasn't over tight then plugged back it but does the cleaning cycle really fast and doesn't move at all with the bike on any ideas

    @vtrn_raptor it won't move until you start to rev the bike mate. I think it starts to open up around 6000rpm

              @vtrn_raptor Yeah it won't, I don't think it does at all in neutral.

              It's easy to tell if the servo is operated as it will pull right through the rev range.

                It doesn't move at all and the cleaning cycle is really erratic

                  @vtrn_raptor Bad battery can do that. Also if it isn't setup the correct way, i.e. the cables the wrog way round.

                    The cables are the right way round I followed a Haynes manual the servos exactly the same without cables connected so ima try the new servo then battery if not either I'll replace the cdi bike was pinned via the servo and could be the reason it was pinned in the first place

                      Any news on this thread? Did the new servo sort it as mine does the same thing.

                        Old thread alert, but! My servo was doing this when I used inferior 2stroke oil and the power valve was gummed up and sticky. As soon as I cleaned of the varnish/gumpf it operated sweet and smooth…
