For a 1.75" track we use a different helix and secondary spring. The added traction of the taller track will show significant increases in the low to midrange acceleration as well as a much better backshift than stock.
 
Just uncrated the XTX last night. I believe we will have just the Stage 1 kit for the XTX.

Allen did you take a peek to see what the xtx has for gearing??
 
XTX has the same gearing as the regular FX Nytro models. 21/39

what exactly is the windage plate kit?

The windage plate kit is two plates that cover up the exposed fins on the secondary. This usually picks up 1-2 mph on top end.

Has anyone had any experience with the Stage Two clutch kit and its claims?
 
We have setup our own MTX at 1300 foot elevation using the same basic components as our Stage 1 clutch kits. We can set you up with a MTX clutch kit if you would like.
