Two Strokes don't have exhaust valves water cooled four stroke technology is totally different from 2-stroke technology so you're blowing it out your ass.
Oxygen is an accelerant if there is enough fuel to burn it will burn faster with a maximum efficiency of oxygen.
And if you're tuning your shit so fucking lean that it can't fire efficiently you're already so lean it's going to bog and you'll never get any power.
Yes you're a fucking retard it's a 2-stroke that we're talking about.
And these four strokes referring to have an ignition system that's putting out 80 KV.
And is running a very large gap in order to ignite the fuel fuel molecules within that Gap.
It's not a fucking moped moron.
Most moped even with a CDI your lucky to have 25 KV maybe, 15 kV on a point system.
And most of the Wiki's out there in the universe are made up by fools like you. (edited)
