saving a 1980 KZ750 twin

I would use tubing between the frame rails and drop say a piece of 10ga. straight down to the engine.

It thought about that but it doesn't allow the coil to be mounted under the tank. A member over at KZR suggested the use of "spherical washers" to deal with the tolerance issues, I had never heard of these before, pretty cool piece of hardware. The only spherical washers i have found can compensate for 3 degrees, but i figure one at the valve cover and one at the frame mount and it would work. I need to evaluate my options.
 
Got started on the muffler, ill let the pictures do the talkin. I need to decide on what style of end-cap I will turn out of aluminum.

Whoa, amazing craftsmanship again man! Love the little tool to make the flares and the fact that you polished the welds. Even though they were nice, it has become such a fad to have the segmented tig'd exhausts!

Edit: End cap No3 for sure!
 
Thanks guys. i just bent some chromoly tube for the passenger footpegs/hanger for the exhaust. I think i will have some time tomorrow to work on it.

Thanks! I hate trends, but by building this style of bike I'm already chasing a trend so I'm trying to keep it different in subtle ways.

My thought also; #2 looks good but would probably accumulate dirt, grease, carbon, etc.

Crazy

Yeah #2 is probably the least practical, but I think I like it the best because it looks like the old kerker baffle, which I am drawing on for inspiration for that old school go fast look.

I had this idea to make a badge in the same font as the old Kerker logo but say KILLER instead. But then i thought... why? because killer is bad ass? I don't know. I feel like a trick exhaust needs a sweet badge.

Haha! just goes to show that NO idea is truly original
 
You are doing a bodacious work on that z750... here's another photo of the badge taken from a friend's bike.

thanks man. that badge is cool. i need to think of something to put on mine.

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 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.

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.

Got a pic from a little bit away? I'd love to see the whole thing with the exhaust now. She's awesome man!!

Small garage ;) I'll role her out soon. I did finish the exhaust, but nee 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.
