    @calum will normal grease do? Such grease you use on the wheel axles for example?

    @irongamer727 Yeah, as said, I really wouldn't go mad on it, cause it's going to burn off any how. Two stroke will probably be the best option here.

      @irongamer727 I used 2 stroke on mine so do as I did as I think the grease is highly not needed and I personally would not trust the grease as I’ve heated grease up general purpose ad it gets quite waxy and may even combust

        Didnt bother lubing my PV after rebuilding, ensured all surfaces were very clean and mirror polished, it doesnt do a full rotation and moves as much as say a rev counter or speedometer, the bushes would well outlast a piston un lubed, the thing you should really worry about it carbon sticking to the powervalve, so keep it clean and if you can be arsed mirror polish it.

          @glynn123 when cleaning the pv. Should you always buy new o rings or can they normally be reused? How many km until you should inspect and clean?

            @irongamer727 Pretty sure it comes with the Athena gasket kit.

            I can't say I have ever gone out my way to replace the o ring or clean the valve.

                  The Haynes manual says you need to make sure the pv is mounted correctly and not 180° wrong. Is it possible to mount it wrong? I mean it only fits one way?

                    @irongamer727 I guess it’s in the manual for a reason but I don’t actually know

                      @irongamer727 It means ensuring it's not upside down....I'd imagine.

                        Yup, it seems you can fit it upside down, thus restricking the bike.
                        Im pretty sure some bikes where sold in a restricted version like this.

                          Can you twist and turn the servo motor for the pv without risking causing damage to it? I need to do so since the current setting is not optimal.

                            @irongamer727 Your servo is fubar anyway right? So can't see what harm it would do.

                                  my question is wheather or not you could "rotate" the servo manually in order to adjust the pv better. The 2nd pulley is obviously a bit too far out.

                                    Yeah isn't that how you're meant to adjust them anyway. Just use a set of spanners to adjust the locking nuts, the tension ought to pull the servo the right way. Then lock off.

                                    I might be having a mental block, but that's how you adjust them.

                                      @calum think he might mean litteraly turning with your finger tips but the way you mentioned is the best way

                                        @declan I think turn it from the PV housing should suffice.

                                          @calum yep to turn it with with your fingers would be massively overkill really
