        you should consider using a better quality oil and using yamahas ring free.

          It runs on all 6 cylinders anytime it's in gear. The middle two cylinders are shutoff only when it's in neutral. I agree, run a better oil and run RingFree or SeaFoam in the gas.

            first of all to hamfisted. this the 250efi does not run on all 6 cylinders when in gear. only above 1800rpms does it run on all 6 cylinders. dont confuse this with the hpdi. now to martin, i agree with jb. use yamaha oil and ring free and it should cure this plug fouling problem.

                de-carb and run ring free
                run upper end oil also
                we slow ***** from salmon and after 800hr and ring free no o2 sensor change yet
