So after putting multiple bandaids on my exhaust bracket and race exhaust mount, the time has come to officially do something about it. You will see from the pics below what had happened. Here you can see how the exhaust mount has been rubbing and eating away at the hangar.  Here you can see the elongated mounting holes from the vibrations as well as the crappy weld from it cracking in half  A shot of both together. As you can see they are not in good shape.  So on to the fix. First i started with water jetting out a new hangar made out of solid 3/8" thick plate.   Im sure i will have to counter sink the holes where it bolts to the motor but for now this is my starting point. I am welding up a new mounting bracket for the exhaust clamp that will look pretty much exaxtly like the old one, just new. Then i will machine some delrin sleeves/ spacers to go into the new hangar. Stay tuned for updates. | ||

Wouldn t the updated y bracket work? Also if you want a more stout race muffler shoe search the site Dave made some that are better | ||

S1owner. Im sure the Y mount would have worked but i didnt wanna try and track one down and also i can use all the material and machines for free so i figured "Y" not. It may not even work in the long run but i figured it couldn't hurt to try. Literally have nothing to lose. | ||

Makes sense I am not familiar with the race set up that well! Def looks beefy!! | ||

If you want the updated shoe Dean adams can help you out http://www.badweatherbikers.com/buell/messages/476 23/786234.html?1464388446 | ||

Thanks will keep that in mind. Gonna weld up the mount here first and see how it works out. Will update with more pics. | ||

OK, So i finally got some time on the waterjet and was able to finish the assembly. The bracket that mounts to the pipe is basically an exact replica of the original. I couldn't find the bushing so i had to get creative. The bushing is rubber with a delrin core in it for the bolt. Its nice and solid but you are still able to slightly move it around so i think i will work well with flexing and vibration damping. I think it came out pretty good. I still have to paint it obviously, but you can see how it looks for now.   | ||

I like the delrin in there. Nice work. | ||

Looks good, Can You post a link for the rubber and delrin core? Thank,s | ||
| S1owner |
Looks nice Did you re fabthe shoe also looks heavier? | ||

everything you see besides the rubber and the bolt is fabbed up from scratch. As for the rubber and the core. Now don't laugh but i had to get "creative". The two rubber halves consist of these 5/8" rubber leg tips. http://www.homedepot.com/p/Everbilt-5-8-in-Off-Whi te-Rubber-Leg-Tips-4-per-Pack-49118/203661014 The ID of these are the 5/8" and the OD is slightly bigger that the hole in the bracket. After sanding 2 of the down to create the "halves" i ended up with the bushings. i then took this Nylon Spacer http://www.homedepot.com/p/Everbilt-1-4-in-x-5-8-i n-x-3-8-in-Nylon-Spacer-815078/204276563 And used that as the "core". Since the OD of the spacer is the exact fit for the ID of the rubber bushing then all i had to do was open up the hole to fit the mounting bolt. I know they are not perfect but i think this might work. Obviously i have t put some miles on it and see how the heat is going to affect it. The way i see it is I have about $10-$20 into this whole project so i dont have much to lose. Anyway, here is how the bushing is arranged.   In the bottom pic you can see the Nylon "core" that fit snugly into the rubber bushing. Like i said, time will tell how this holds up. | ||

You may find that you need more of a lip on the shoe to stop the clamp from sliding off. | ||

Or just put a couple of nylon washers on either side of the support over the bolt. You probably don't actually need the compressibility out there, where you want the flex is probably that inside bushing. | ||

Here is the main bracket installed. And yes, i know my chin spoiler has seen better days.  | ||

@Mike. I love Hardware Store Engineering, and I sincerely mean that. I have to say that I'm amused at your combined mix of H/W store Engineering and High Tech Metal work.  . I hope it works out. | ||

Thanks Jim! I am a mechanical engineer so i have access to some pretty cool toys. I dont have any access to anything that has to do with rubber so thats where i have to get creative. I will be sure to check back in after i put some miles on it. |
