I cut off the buckles (leaving the loops intact) and drilled some holes in the seat pan to get a Coleman Comfort Ride(TM) Seat Protector to fit like a glove.

Trunk fit beautifully, just needed some large nuts to raise it enough that I can get the seat on and off and the rear slots had to be filed a little bit to line up with the bolt holes on the Hawk. The trunk is easily removed, just turn the key and press a button. Now I just need a tank bag and some saddle bags.

With the stock carb, I removed the plug over the idle mixture screw and turned it out 1 3/4 turns. I used a center punch to indent and then tap off the tamper proof screws, shimmed up the needle with three #4 washers and replaced the main jet with a large round size 110 (N100.604/110).

Replaced the front sprocket with a 17 tooth one. Discovered you can't get the cover back on with the chain on the 17 tooth, have to put the chain on after the cover is installed.
