i was cleaning up my 99 S-3 for a ride to cedar key tomorrow...80 degrees and sunny.. i looked at the front muffler mount on my race pipe and i see that the bracket that clamps onto the front of the pipe is broken.. i see that American Sport Bike sells replacements, but this part looks like it will break again...any permanent solutions... how about any short term ones that will let me ride to cedar key?  i know that i dont have the upgraded Y bracket, but thats not the part thats broken.. | ||

Many many posts on this, and the y-bracket has little to do with this, in my opinion. There was a bracket posted elsewhere that used a band clamp, and I thought that looked really good. Full pipe enclosure, still allowed some growth/flex, etc. | ||

The first thing I see wrong with that picture is your front isolator bushing is wiped out. The shoes have a decent chance of survival if all the bushings are in good shape and there is good vibration dampening. Once the bushings wear the metal fatigues quickly. Also when you mount up your complete ex system front to back there should be no preload on these bushings. In other words you should not have to force the mounting bolts thru the bushings, the lower exhaust should just kind of hang in the bushings not be forced into an unnatural position by them. Unfortunately this is sometimes easier said than done. | ||

should the bushing be trashed with only four thousand miles on the bike? | ||

 this is a picture of a front mount and bushing collars I made(from an earlier post)I also mocked everything up and tack welded the shoe in place so everything fit just right. Then removed it and completely welded the shoe in place.The original shoe with the clamp,would tend to walk down and across the pipe to a place it was happiest because of the shape of the collector at that point, but thats not where the bushing would prefer it to be. My original problem was wearing the bushing out laterally. It looks like yours was preloaded longitudinally | ||

should the bushing be trashed with only four thousand miles on the bike? Yeah mine never lasted to long, finally one day I sat down and took a look at the whole exhaust system and tried to cypher out why I was having this problem. Unbolted things and looked at all the mounts and figured it out. If you look at your exh sys mounting carefully you will see that it is totally mounted to the motor essentially. Unlike a lot of jap bikes where the front headerpipes mount to the engine and the canister mounts to the frame. At first I thought that was the problem. So even though our motors vibrate a lot the exhaust is at one with the motor, our exhaust is not fighting a rubber mounted motor against the frame. Our front and rear ex mounts both mount to the motor assy.So I came to the conclusion that preload on the bushings was the most likely cause of my mount/bushing failures. Since I looked at it this way and configured it accordingly, I havent had any issues. also check your upper rear "Z" mount bushings, there are updated parts for these. The following I cut and pasted from my earlier post so you wouldnt have to search, it goes with the picture above "Machined this front mount from 7075 aluminum. I made it to accept the updated upper rear "Z" mount rubber bushings. Then machined 2 stainless steel flanged bushings to fit inside the rubber bushings and between the pipe mounting bracket. Then reinforced and TIG welded the SS pipe mount bracket to the pipe(no more funky muffler clamp to break).Had the machined bracket black anodized to match original also. Works very good so far, and the bushings are readily available.Never liked the looks of that retrofit Tri-Y bracket buell came up with" | ||

My 2000 S3 bushing only made it to about 3000 miles -- had lots of issues with broken metal mounts and one broken exhaust stud -- installed the Y hanger 7000 miles ago -- no issues since -- | ||

Dave(Werewulf), pictured below is my cure for many of these breakages we experience. Not the greatest looking but a band clamp completely around the pipe and these springs, really work. I do both front and rear hangers as you can see. They aleviate much of the strain on parts and allow SOME flexing, which is good, to keep strain away from the header to head, bolts/studs. Occasionally a spring will break showing that they really do work for their intended purpose and they are available at Home Depot for a few bucks for four(4). At least another consideration.

Check this mount for the race kit exhaust by Stenzel. I don't know anything about it, but it looks cool. The mount is shown at the bottom of the link. http://www.stenzel-parts.de/14321.html I'll be trying this if my cobbled together race kit header/V&H muffler combo doesn't pan out (it has so far). Instead of modifying the part that has a reputation for breaking on the race kit exhaust, I changed the forces it had to deal with by using a lighter aluminum muffler rather than the stainless steel race kit muffler. I still use the stock single point mount (not the Y) and haven't had a problem in 15,000 miles. Still on the old rubber bushing too. | ||

Here's a link that shows my set-up... it's in the middle of the thread. http://www.badweatherbikers.com/buell/messages/384 2/297373.html?1187494647 | ||

Dan(Djkaplan), I really like that mount (yours) as it uses the rubber bushing to relieve some stresses and a full circumference band clamp. Nice job my friend. Bob | ||
| Djkaplan |
That's the same race kit mounting shoe and clamp as Werewulf's. I didn't change it at all, I just hung a much lighter muffler from it. It's exactly like Werewulf's set-up that broke. You would not believe the weight difference between the large SS race muffler and the much smaller aluminum V&H. The race muffler sounds better, but I think the weight of it kills the mounting shoe, even with the Y-mount it seems. | ||

ref: http://www.stenzel-parts.de/14321.html .. anyone speak german?? i sent an order via paypal 2 weeks ago and have not recieved the part.. i sent him an email and i could tell from his answer that we had a language problem... i emailed him again and got no response... how long should it take a part to be mailed frome germany?? | ||
| Werewulf |
im tempted to put the stock pipes back on and get them ceramic coated... my S-3 runs so fine with the race pipe, that i would hate to mess that up, as i dont know if the power would suffer a bunch from the stocker... | ||
| Werewulf |
well, ask and you will recieve... http://www.stenzel-parts.de/14321.html just sent me an email... the parts were mailed and returned to him, due to lack of a zip code... he even sent me a photo of the package... i think he is a good and honest business man... | ||

Thomson, is that a CHERRY BOMB UNDER YOUR BIKE??? | ||
| Hugie03flhr |
Wish I thought of that!!! | ||
| Werewulf |
looks like a kooks set-up.. i just saw one on ebay.. | ||
| Bob_thompson |
Bill(Hugie03flhr), Yes, pretty much what most people call them. after installing a 2 1/2" bend to the stock header I used one from either Jegs or Summit racing. Inexpensive at about $30 and many different kinds to choose from. I now have a full fairing on my M2 so it looks really great (read hidden behind the fairing). But you can get many kinds with packing, spiral baffles, and others systems in SS, chrome, aluminum and carbon fiber. Just pick what you like and can afford. | ||

I'm kind of wondering what the point of the Stenzel top brace mount thingie is.... | ||
| Werewulf |
it is claimed that the stenzel stabilized the motormount and prevents the head bolt breaking... daytona harley used to sell a stainless glass pak for the tubers made by sebastian stainless company, if i remember correctly.. i called the company and they refused to make up one for me...the said they had too many mount failures.... | ||
| Bob_thompson |
Dave(Werewulf), did the company you called explain what the failures were with the mounts? Usually this has been welds with other mfgr's and why I use full circular clamps and hangers. My own experience has been very positive with my setup. Again not real pretty but highly functional. It could, however, BE pretty with a nicer looking carbon fiber or other unit. Bob | ||
| Werewulf |
bob, the company just said that they couldnt keep the mounts from breaking... i asked if he would make up just one more and he declined...i like your mounting system, do you have a close-up of the front mount? | ||
| Bob_thompson |
Dave, thanks. No closeup and its behind the fairing now so kind of hard to photograph but it uses the stock y mount and two small tabs on either side bent out slightly held by the stock y mount bolt (the long one). Then the springs are attached there and at the bolt that goes through the 2 piece clamp on each side. Same in the back. Stock hanger, etc. A spring on each side stabilizes it side to side and the stiffness of the springs keep it up securely but all this still allows some vibration damping effects. This is an old dirt bike trick where almost all singles vibrate tremendously. I might add, I did this some 7000 miles ago and have had only springs break as a sacrificial lamb. No cracks anywhere and head bolts for exhaust are still tight. Bob | ||
| Djkaplan |
I like the way it looks, Bob. There is an aesthetic quality to function sans form that I appreciate. Plus... you can't beat the price. | ||

Thanks DJ and Dave(Werewulf), I photoshopped my original picture to be lighter and zoomed in. Any closer and it became blurry due to my 2.0 digital camera. see below. Hope this helps and thanks again guys. Form FOLLOWS function every time for me also.  |
