I definitely didn't make it easy on myself to pack the muffler with the kinks in the can. I bought a kit with stainless mesh, stainless mat, and fiberglass mat, its is in there very snugly. The perforated core isn't attached on either end but is wedged between the two ends, hopefully this will negate fatigue issues. I also finished the left passenger peg.

Got around to finishing the top motor mount. I ended up doing something similar to what NebrRex suggested. I used a 3/8" reamer in a hand drill to bore out the mounts and at the same time got them pretty close to axial, they were a little off before preventing a bolt through bolt mounts, so now I can through bolt side to side with spacers so it not only supports the motor but ties it all together and increases frame rigidity. I also milled the valve cover to remove the draft on it and now the mounting points are parallel. I ended up having to offset the coil to make clearance for the throttle cables and electrics that will go through the backbone as well. I like that you can see the mounts if you bend down to inspect the bike. I also refinished the tank and side cover badges I bought as I hate flat black paint, and the white didn't match the shocks or tank. details....
