My shen doesn't like taking my BCG motor (with either the bit pinion OR the shen one) or my BCG gearsets...whats the deal? Should I try the 7 tooth pinion or what? The mesh is so tight when I put in my other gearsets that its hard to even turn by rolling the axle with my fingers.
Anyone else with shens please post about your gearing and if it was possible for you to change the setup. Thanks guys.
hmmm very strange, I have no problem changing gears/motors with my Shens and MSizers. Though I find the Shen Motor out performs the MSizer. Let me know what you find out. Sorry I can't be of more help.

You can tighten up or loosen up the gearing a little by rotating the motor in the compartment. If you place the the motor in with the metal tab toward the front of the car, it will push the pinion gear away from the chassis gear a little freeing it up some. If you place the motor in with the metal tab toward the rear of the car, it will press the pinion gear toward the chassis gear and tighten things up. I hope this helps you out. I haven't had this problem with my Shen car. I just pop in a 3.8 and zoom zoom zoom.
