Any ONE HAD ANY EXP: with 3cv motors

I thought you where using a Rotax on that mini:?: if so witch one ? you can step up the RPM with a programmable Rev-limiter . Rotax has factory gear box's A,B,C,D, E with different ratios but a Cog belt setup for a homemade reduction should work out you need to find a way to lock the pulley in on the shaft as those are splined and if you change that heavy PTO to a Lighted Aluminum you get better Snap

something like this with a different back plate :
