    One of the guys shared these on the Aprilia MX group, so I thought that they might be useful to someone on here as well???

      The basic rule for off-roaders is 2%, but as always check what your manufacturer says before listening to advice!

        Yeah, most use 2% as a rule of thumb

        I saw a chart on the auto-pump back in the days, as I recall it pumped out 3-4% af WOT, and way less just idling or at low throttle operations. Kinda shows you the beaty of the auto-pump.

        Some info here: http://www.dansmc.com/2_stroke_oilpump.htm
