If I switch to premix how will it affect MPG? On a S4 can I disconect the rod from the throttle to the OMP to disable/bypass it? BTW the FAQ thread has nothing to do with premix

theoriotically, premixing does affect the fuel economy very slightly, since fuel burns better and cleaner than 2 stroke oil. However, after using it for so long, i can tell you that the difference is not very noticable.

On S4 if you disconnect the rod, the OMP still spins from the gear behind it, rotated by the eccentric shaft. Therefor, small amount of oil will still be injecting into the engine. The best way to by pass it will be taking out the benjo bolts on the OMP, and replace them with regular bolts. This way the oil will not be able to run through the lines.

Unbolt the OMP, oil injectors, disconnect the rod that runs to the tb. Put bolts in the oil injector holes and then get a piece of 1/8 or 1/4in thick aluminum (or steel) and trace the OMP onto it. Cut the shape out, drill 2 holes in it and bolt it in place of the OMP.

Does using premix effect your emissions?

you are now burning oil with your gas, emissions will suffer, and

you will have a nice sotty back bumper to go with it. Havent you ever seen

the smoke and stink that comes from a 2 cycle?
