sorry to have to do this - I tried email but it comes back undeliverable - need some info on your motion pro - I tried some time ago to get one but was told "special order". Was yours, or are they now available to the unwashed masses

 

I used a "universal" setup for dirtbikes/atv's. Motion Pro "Turbo" twist throttle p/n: 01-057.
The cable I used was definatly for a dirtbike since it is little too long for the atv. But, I re-routed it to take up the slack without putting the cable in a bind, or in harms way.
The cable was Motion Pro p/n: M.P. 01-236.
This cable may be avialable in shorter lengths with the same ends, but, the shop I was at didn't have it in stock, and this worked for me.
I ended up shifting everthing to the left on the handlebar, kept the housing so the 4wd switch would have a mounting place, but removed the thumb lever & linkage inside the housing. (Be sure to plug up the holes).
I'll never go back to a thumb throttle again!!!
