I purchased pro taper pillow top grips for my son's DR200. The left grip came off right away but the right grip is bonded to the throttle assembly. Upon removal of the assembly I see that there is only one cable connected to it so it is not push pull. I don't want to purchase the stock assembly as I want to put on the new grips. Any recommendations for a replacement? The outer bar diameter is about 1/16" less than 7/8 inch. Thanks in advance.
