fxt sprocket size
« on: March 03, 2016, 03:12:13 pm »
Building my first fxt mower and wondering what a good starting point for sprocket sizes would be.  I understand everyone will be different but just want to get in the ball park to start.

Thanks

I've been racing for a few years.

12x9x6 tires and probably 6-8K rpms  Just wanted a ballpark.  It will be a horizontal shaft with jackshaft.
