Below are a few pictures of the assembly going back together. If you look at the pictures carefully, you will be able to orient the (2) cables properly in the housing. Then, you simply screw the housing together and you are done.
If the mod is done properly, you will notice that it takes significantly less twist of the wrist to get the throttle open.
Since the 250's do not output a lot of juice, this mod can be quite helpful, especially on freeways or riding nice and hard.
I just finished completing the mod only moments ago, so I will do a review on my test ride today.
