i looked 4 your article but no found tell me how you did it talked to mike pennland today and he said he would make me up 1 twist throtle that is what cable and what throtle did you use thanks

 

700WHEELIEMAN... you can certainly get one from Mike Pendland if you'd like to...
or
you can order one from Motion Pro, for the 400 Prairie... it fits right on, the problem is the 2 X 4 - 4 X 4 switch, that is attached to the thumb throttle... to fix this, I cut a rectangle just slightly bigger than the switch it self ( not the switch body )... I did this on the handle bar shroud on the front, at the bend ( this leaves room for the switch ( removed from the thumb throttle ), between the shroud, & the bar )... 2 screws hold it in place... works perfectly...
