I've tried numerous gearing, to many to keep track, I find this to be the best one.
It has enough power to make all wheels spin on take off, when I'm on the top of 1st gear, and press full throttle all wheels are spinning when it changes to 2nd gear.
My goal was to make the MT2 crack the 60mph.
I've been to busy this summer to play around with it, not counting I just bought a home, and the money has been going to the home.

I'm hopping to give it another run to see if the mods above will increase top speed or not.
