      So let's say you put 10ml into your fuel will that be the same as the oil pump would normally do when at idle?

        I don't know if anyone would have measurable amount for you, but I'm just wondering why you want to know? Are you seeing how little you can get away with whilst you are tinkering with the bike?

          @Mightyman no that would end in catastrophe lol I just want a little extra protection at idle and low revs while I run the autolube

            No that's not how it works.

            The fuel/air is drawn in through the throttle slide.

            So has you increase the throttle, you increase the fuel/air. If you mix the oil in then altering the throttle alters the fuel/air/oil. Therefore it works just like the oil pump on idle.

            Again, please open these up in the correct section.

                  @declan Well it's a carburetor engine isn't it.

                    @Calum what I'm asking is what amount would you reccomend I put in to richen the oil mix in conjunction with the oil pump currently I'm running 150ml to 5l with the oil pump and it seems like 50ml with the oil pump would be decent I know it's not a very straight forward question but I'm just gauging your opinion and input as all of this is a learning experience for me thank you.

                      @declan Why are you adding oil to the fuel?

                      150ml to 5L of fuel, dayum, that's like no oil pump territory.

                          @declan Yeah well it's going to foul plugs at that rate mate. Which means it's going to break down and run like a dog.

                              Running that much oil with the pump as well is seriously pointless. If the pump is working correctly there is no need to be putting more oil into the fuel. I put double my usual amount of oil into my KTM 250 EXC a couple years back and I'm pretty sure it was the cause of the piston seizing, about 15 minutes into riding.

                                @Mightyman Gums up the piston rings causing them to stick.

                                Also fouls the plugs. It's going to cause more problems than it's worth.

                                  @declan Please follow the Manufacturer recommendations first before asking any of us.

                                  It's best to 'guestimate' a healthy oil supply from that. But, from experience, as less oil you can work with the better!

                                  I run my DT on a 42:1 mixture still. These road going 2strokes just don't require heavy lubrication.

                                  Keep it real

                                    @Darty true! And tbh even today's Mx bikes don't need a ridiculous amount of oil. KTM recommends 50:1 with most of their line up. I think the freeride series are even less like 80:1???
                                    Just read their newer bikes are on 80:1 with some people even going as low as 100:1 !

                                        @Mightyman I was reading in Motocross Action Magazine that Husqvarna were recommending going from 40:1 to 60:1 to fix the jetting issues the MXA test team were having when running the 2017' TC250.

                                        And it it worked! Incredible for a complete MX race engine.

                                          @Darty I wonder if that's because competition 2 strokes have a shitty service life so they only need to last a race before rebuild since leaner is faster in most cases

                                            @declan yeah that is probably also the case.
