    @Bentley Nah I'm not a mechanic bud.

    There isn't much really too these bikes so you pick it up fairly quickly. It won't be long before you're be the one people ask for answers 😄

    Unfortunately, like most, I've learned the hard way. But it's worth every penny as now there is very little I fret in undertaking.

            @Zrako that was the usual recommended one on the old forum 👍 But tbh, as long as your clutch isn't slipping and your gear changes are Smooth enough, your alright!

                @Zrako Austin mini anyone? Shared the same fluid with the engine as the gearbox.

                  @Calum I'm pretty sure the Yamaha WR 125 shares gearbox and engine oil, makes a lot of sense IMO.

                    @Mightyman My point exactly. I use engine oil and never had a problem.

                    Obviously as you put more power through the transmission then it's best to have something designed for the application. But 125's ought to be fine.

                      its because car oil engine make clutch slip, motorcycle/ATV etc.. engine oil is fine.

                        @pelplouffe As said that is all I have ever run and my clutch has been fine. Only with the magnetec stuff did the clutch slip.

                          I'd always check the powervalve is working correctly, the condition of the reeds, clean air filter, clean plug, fueling is correct, to start with. Big gains from doing this this if they aren't right.

                              Most 4 stroke bikes use the same oil for engine and gearbox, so any bike oil will be fine.

                              But car oil is a no no as it has additives in that will make the clutch slip.

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