Mini apes will bolt right on, you don't need new risors or relocate your speedo. Just longer cables an wires. You don't say if it's a custom, that may be a little more challenging, but doable. Theres pics in my garage.
Bars are bars, you take the top clamp off and put a new set of bars on. As long as they are the right size ( 1 inch ) they will fit. What you will need is longer cables and wires. I went through Burly Brand for my 12 inch apes that are on top of the stock riser on my 02 sporty. Great instructions and great quality.
