Here is a rough how-to for lowering your instrument cluster like the previously referenced Monster 696. I don't have the time to post images so you'll have to visualize along the way. This is just ONE way, there are others I'm sure.
Step 1: Remove the instrument cluster from the headlight casting 'ears' (4 screws and cluster pig tail)
Step 2: The scary part...cut off the silver mounting 'ears' from the headlight casting with a dremel or saw...it cuts easy, its soft aluminum.
Step 3: Shape and smooth the cut to blend with two black plastic humps on the the top of the headlight. Its best to paint or PC the whole silver casting after this to make it blend better.
Step 4: The creative part: Fabricating new mounts. You can use 1" x 1/8" alum strips or similar. You can use the mounting holes on the bottom of the triple tree or the upper headlight mounts on the triple. If your using clipons you also have the riser holes to choose from. This step takes some bending, cutting, and fabrication skills and lots of trial and error for proper fitment.
Like I said, not so easy, and definitely time consuming. But looks infinitely better when complete. Good luck!
