thats wack 😀
normally the 2speed isnt that fast, ratios are way to tiny
as shown here there is a big difference fith the 2speed and 3 speed.
you might want to experiment with the pulley on the engine, i think it wont go super fast like variomatic or normal gearbox
but then you cannon shift 😀
i love shifting gears, can`t wait to hear you rip trough the gears with a big 46mm block 😀
