Well, I just received my 05 Mtnviper cable. Some modifications are required to make it fit on the 02 throttle lever block. The 05 cable housing end is a little larger diameter (approx 1/64-1/32") and a different shape. It does require some drilling in the plastic throttle lever block. Not a huge deal, but takes some more time.
The 05 cable has a splitter in it for the oil cable. When you buy the 05 cable, you are replacing both the oil and throttle cable's with one cable. At the carb's and oil pump, the hook-up's are the same.
The 05 cable is approx 2" longer. I am going to a 3 1/4 pivot riser, from a 2" riser, with the 05 cable I could go even higher no problem.
