Please note my conversion does not use the El Cheapo combined fatbar adapter and riser which stack on top of the OEM clamps like Legos and move the bars up parallel to the steering axis.
It's completely new 28mm diameter clamps with a set of shims to adjust the height.
The handlebar clamps are machined off centre and are reversible to give additional adjustability to move the bars further forward (which makes sense) or closer to the seat (which does not make sense

) The important part is that the bars move up AND forward.
The looks of the assembly are much cleaner than the Lego block type risers stacked on top of the OEM clamps.
