i just mounted the motor in the frame and i am on step # 6 from his webpage. it says to tighten down the throttle but there is just one problem, there is no way for me to tighten down the throttle. attached is the pictures of the pieces i have for the throttle, which look nothing like the pieces he used in his picture. at this point i'm kinda dissapointed and frustrated. what do i do? on a side note the last picture is where the throttle is going. this is a grip-shift bike. has anyone ever installed a throttle on a grip-shift bike? the throttle fits on but i have not been provided (at least i don't think i have been) any tools or pieces that will tighten it down. any suggestions?
