I just put the shogun frame sliders on my F4i and thought it was cake...I do build customs trucks and have mechanical know how, but its really not that hard....if you pull the fairing, theres a foam pad on the backside....I unscrewed the upper engine mount bolt enough that when I put the fairing back on, it left an impression in the foam....the drilled a pilot hole and used a hole saw kit....I believe the hole saw was 1 3/4 and both sides came out dead on the money...make sure you use duct tape where your drilling to keep from scratching the fairing or messing up the paint...take your time....measure twice, cut one time... Holla if you have any questions...Peace Jack
