Better clarify what i stated earlier,
with a capacitor they will start with a kick starter, obviously would need to be a huge capacitor to enable a starter motor, this is how i understand the MXers operate capacitor & kick and they need to be started in a hurry when they go down, look at a video of Bubba when it happens, one kick and he’s gooooone. Now as an aside isn’t it funny (not in a haha haha sorta way either) how they get all the technology first, Ala KTM all the new stuff goes on the SXs before EXCs, although Gas gas has had it for quite a while now on the 450.
