As I said earlier, I suspect the front wheel might hit the oil cooler with full compression of the forks. This is a valid concern, so I want to provide some additional information. I have installed a lowering link, and raised my forks 1-inch in the triple tree. I don't know how much free sag I have with my current forks. The doctored photograph below shows approximately how much the front wheel can travel before it impacts the oil cooler on my lowered motorcycle.
I think I can raise the oil cooler about an inch, if necessary. I can also trim the rear of the fender so the wheel will not grab it long before it would impact the fender. When I get a chance, I will lift the front wheel and see how much free sag I have in my forks.
