For a small tight track,you should run small tires,like 58frt,60 rear, the Rev works its best with small tires.The clutch setup, you need to find a 1/8 scale hard spring,second the flyweights should be drilled an add 2 grub screws in each flyweight.Also did you see if the V1RRR clutch or Mtx4 clutch kit.I,ve been running since day 1 an still running it.
