      No difference in peak power, but using the servo you'll get a broader range, so you'll have better low and mid range. Obviously it depends on exactly where you've pinned your power valve

      Current bikes:
      DT125X '07
      Street Triple R '11
      Aprilia ETV1000 '02

          Mine was pinned when i bought the bike, reinstating the servo etc made a huge difference for me

            Pinned all the way. You gain everything and lose nothing.

            Unless your CDI is restricted, that'll cause the valve to shut after a certain RPM.

            Zeeltronic gives you complete control of when the valve opens and shuts, allowing you to really get the full potential of the YPVS. Big gains to be made with a custom ignition.

              So keeping it pinned is better

                I would try it with the servo when it's pinned there is no power at low revs
                Perhaps it's unplugged for a reason I would take the pv out an clean it toke sure it's not sticking then connect the servo up an try it

                  @vtrn_raptor Jeez I really messed that up. Sorry no, Servo all the way.

                  Don't pin use the servo. I don't know why I said pinned sorry.

                  Servo is much better.

                    Servo for sure, best of both worlds.

                        @vtrn_raptor can you hear it trying to do it's cycle when you turn your bikes ignition on?

                          Not sure I'll check when I'll plug it all in and check when I'm home

                            Sorry to butt in the thread, but has anyone got any idea why... when I connected up a working servo to the plugs it was completely dead? No cleaning cycle whatsoever, cables not connected so no load on it. Just not working at all. What's the most likely causes? Could it be a CDI issue? (03 DTR) I want to put a servo on desperately. Cheers.

                              Yeah motor can be dead, or faulty cdi.

                              Multi meter on the plugs will tell you.

                                  Or overtightened servo tensioners . I was setting them on and if they are not set properly , the servo will not reset when ignition turned on

                                      @ijohney123 just plug and play mate. My servo was unplugged with the cables overtightened so the pulley didn't move

                                          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
