Wow!
I just went and dug out a KIT pinion, and it does seem to make my shen a little faster! Very cool!

ZZ NOS motor, 7 tooth pinion, and the 8.25:1 rear is a nice combination for me so far. I can hardly wait to try the 2.6 and above motors with this setup.

Great idea!


It didn't work so well on my Cyclona though, but no matter. It's set up to me the next notch down anyway, so no biggie.
