That was a hard bullet to bite for me, bought mine off e bay and at least saved the shipping costs. They went on pretty easy, even the brake/clutch bleeding went pretty well following the instructions. And that is my tip, no matter how many times you have done this type of install, follow their directions if you do it Except for this point. When they say now tighten the Brake line extenders, dont. Just barely tighten them, when you get it all mounted and pretty much lined up, (Sit on it and dial it in) swivel the lines into the right position so they don't touch anything and then and only then crank em down.
It allows you to sit more upright and more weight gets on the seat. So you will be more comfortable. I doubled my riding time in one shot just installing the Heli Bars.
