I just replaced mine about a week ago. The shop charge me 1.5 hrs of labor= $129
just getting the cables off and on the throttle tube was APITA. i was just replacing the throtle grip/tube due to a broken handle bar. i was soo frustrated i was cursing in so many languages!! I was working on the bike outside and it was cold which added to the frustration on hooking up the cables back on the grooves on the tube.
After the experience replacing the broken handle bar where i had to replace my throttle tube and deal w/ the throttle cables. I gladly paid the $I29. I actually felt bad for the guy that did it cuz he had to do them.
I read the 2 DIY writes ups/ both w/ great pictures, tips, instructions. And i also have the service manual. It doesnt seem that hard, ITS JUST PATIENCE W/ THE CABLES
because there seems to be no slack for the cables to be hooked where they are suposed to be...For me the deciding factor to taking it to the shop was the weather and shop rate.
If i had a garage i could have taken my time and learn more about the bike while doing them and feel good after finishing the job!
But no regrets hooking up the cables really is APITA!!
