I am changing my 07 450er back to the stock thumb throttle from twist. I feel that I am pretty mechanically inclined but for the life of me I can not get the cable into the the throttle housing. As far as I can tell the throttle arm does not unbolt which, would solve all of my problems. (yes I have the cable inside the throttle assembly, I just cannot connect the cable to the arm because of the angle). The throttle assembly is a stock 2007 450er.

Thanks for the help
