small update but I really liked how simple this ended up being. When the forks were turned fully to the left the throttle cables would push over to the far side of the handle bar riser bolt, then when turned back they would get stuck there and cause the front end to get stuck, not good. I made this dead simple hook that bolts on to the handlebar riser to keep the cables tidy and also prevents them from rubbing on the headlight/tach

Made progress on the hanger and exhaust mount. I'm using some Tarrozi folding pegs that were intended for a different project. They're a tad long for passenger pegs so I will probably cut them down eventually. The mounting bungs i originally turned were too big to look good so I remade made them. I'm not sure I like the placement of the "load spreader" (for lack of a better term.) The part on the muffler can that actually welds to the muffler, not the tab that connects to the rubber mount. It looks a bit odd to me, i might end up cutting a trapezoidal one to follow the lines better. I think there has to be a cooler way to weld on the tab but I'm not sure. Also I'm wondering if its thick enough; its only .065" while most I've seen have been .125" I don't want it to crack.

i would double layer and stitch the .065 together down the seam for the mounting tab and just use a single layer for the load spreader.
thats my .02 fwiw.

Seriously WOW, Nice work. those are some fantastic welds. Boy how I wish I could weld like that. Been practicing so I can try to build some chambers for my H2 but when I see the good guys do it I want cry!!!

Just lovely! You have a good eye and the skill to back it up! Beautiful build!
I believe its called "Oppositional Defiance Disorder"

thanks guys

Joe - Those welds on the muffler came out extra nice because i went through the trouble of back purging with argon. When you back-purge the stainless welds up real nice. Also a trick my buddy put me on to is get some really thin stainless 304 "crafting" wire for filler rod. The stuff i used was 26 gauge or 0.0187" thick. really makes it easy to get a even flush bead on a butt weld.

Here is the revised mount. the weld got a little funky where the load spreader meets the muffler cause I put some solar flux behind it to minimize "sugaring" and the solar flux contaminated the weld a bit. I will hit it with an "air file" and no one will be the wiser. All that's left on the exhaust is the end cap, packing, and springs/holders for the slip fit.

I pretty much finished the exhaust, but still need to trim a tiny bit off the exhaust flanges and pack the muffler first before it can go back on. Exhaust cap came out pretty nice but i want to trim a little bit more off the lip.
