Here are some mods I made to my Duncan Mosquito.
As you can see it is a hybrid between a sticker recess an a sili recess. For those of you that are observant you can see that it is highwalled. For those of you that are not human in your ability to recegnize mods you will see it also has a longer axel than a regular Mosquito. This along with an extra hex nut makes the adjustable gap more adjustable. I also did some reshaping to the outside to take off vibe.
