Title: Muff aggro - RESOLVED!
Post by skatnbnc on 05/06/08 at 10:56:19

I've about had it with the HD muffler on my bike constantly having to be retightened. Dang thing comes loose every week and has ended up being a daily check along with the usual tcloc.

You all have plenty of posts about alternate types of mufflers to install, but has anyone had the muffler WELDED onto the header pipe? How did that work? Any suggestions (or don't ever do this) advice?

I've got a local welding shop that might be able to do it, but wanted to see if there are any issues before I take the bike in.

Or...should I just replace the clamp-on HD muffler altogether?  :-/

Skatnbnc,
 What are you using to clamp it on to the pipe???  Also, same question for the hanger.

My Dyna (aftermarket) pipe is fairly solid but I had to modify the Suzuki clamp.  (drilled out the threaded part and used a grade 8 bolt).

T.M.

I used the HD camp, and it never came loose.  I used Loctite red stud setting on the threads.

Never had this problem in particular, but Loctite Red has stopped a lot of problems over the years and I would try it before resorting to the weld. Good stuff!

Ride safe

On the FireLizard my Jardine is welded to the pipe. (It was that way when I got the pipe). Don't really have any problems with it except when I have to take the pipe off to do engine work, even then it really isn't a problem so to speak, just awkward because of the size, length and weight.

Get a "U" shape car muffler clamp and crank that baby down hard. The weld might crack from vibration unless you seal the entire joint.

i have one of those u shaped muffler clamps on mine, it hasn't come loose yet. but it does leak a little.

Post by Max_Morley on 05/06/08 at 18:05:09

I find the HD clamp works very well but I'm using a correct size adapter pipe between the OE head pipe and the muffler as there is some slight difference in size. Max

Hi skatnbnc,

I think it's just a matter of really cranking down on tightning and " Loctite " wouldn't hurt either.

I cranked mine sooooo tight, it started to collapse the pipe  :P

Take care and good luck...Dennis

I had mine welded on and I haven't looked back.

My leg-shield keeps comming loose and rattles, but the muffler is staying in place.

If you have a leg shield, then by all means, get the sportster muff welded in place.

Post by Rockin_John on 05/06/08 at 19:47:31

I'm another from the "welding" school of thought. Get it how you want it; weld it, and forget about it. I had a nice shiny TIG weld done on mine, but even gas welding can look ok on oipes. Plus, you're going to cover the area with a heat shield anyways.  8-)

I'm clamping mine with 2 stock clamps until I'm sure I like it , then I will have the local muffler shop weld it solid.  

Then it will be "No worries" ;)

Hi Skatnbnc,
               If you get to frustrated I have a "Jardene " muffler for sale in the market place,it's a perfect fit all around,it comes with a complete set of jets and a needle,I have it listed for $125 but I haven't had an offer ,so if you make one I would consider it,
be warned this muffler is LOUD ,it also gives you a bit more power.
The chrome is good,very slight bluing at the jount,it's a slash cut ,and looks really cool, let me know.
  PS it come's with all the hardwear you will need.

Post by skatnbnc on 05/07/08 at 05:16:52

My HD was a PO addition, so I do not know what kind or model it is. The muff diameter is smaller than the header, and fits into it.

I've had to make my own attachment for the back portion screw that attaches to the bike (a funky bolted thing), and right now that is mainly what holds it on. If that came off, the pipe would fall off (and it HAS once on an exit ramp during rush hour traffic - urg.)

The clamp holding the muff to the header pipe is a circle clamp with a thumb screw turner (yeah, there is probably a tech term for this, but heck if I know what). I have used lock-tite. It works for holding the pipe about a week longer than when I don't use it.  :P

Muffler fits into the header pipe......   :o  

Most of the HD mufflers I saw numbers on would slip over the outside of our header pipe.  

You may want to have an adapter pipe made to convert from one to the other.   A muffler shop could do it for you.    You may have to bat your baby blues (green or brown....) since when you get there, the pipe will be a tad hot.

Also, the picture you tried to post looks like it is a link to your "e:" drive.  It needs to be up on some web-site, hosting service or web-server.   If your internet service provider (ISP) lets you have a personal website (most do) then store it there.

I think 99.9999% of the muffs fit over the header(yours being the .0001%)
aka Band clamp adjuster, Hose clamp screw, doohicky.

How about using 'muffler cement' ( comes in a tuna fish sized can and is a very thick metalized paste) as a joint sealer, and then 2 tack welds from a mig-welder, and then the clamp?  If you had to remove the muffler, you could easily grind off the tack welds and they are covered by the shield anyway.

Okay guys - tell me the pros and cons of this one on ebay.  It's another HD, but I think it fits on differently than the one I have now.
Item # 150246478019

I skipped on the Jardine because its too loud for me. I commute in a really small town, and my hearing is damaged already so I'm not looking for more noise.

What I am looking for is a muffler that stays on my bike!
http://w3.bikepics.com/pics/2008/01/28/bikepics-1163925-200.jpg
It came off again on my way to lunch today - arrggg. I kicked it back on, (damaged my boot toe) but it was too hot to tighten the clamp, so once again the bolt is holding it in place until tomorrow morning. >:(

Well I managed to scrape the sh*t out of one side, I don't like the sound and it is getting a knarly blue mark from backfire burping where it meets the connector. (see photo above) So a new one is looking better than this one which I have never liked.

Hey MICK that's a real good price on the Jardine Muff and with a Jet Kit???? :o I wish I knew that a few weeks ago! :'( I just paid 170 for muff and 30 for jet kit and YOU are correct!! It Sounds like a Big Boys Bike and does Kick Ass. ;D I used the Clamp  that came with it and if you position the clamp the CORRECT way and with a NEW Gasket from your local StealerShip it tightens down just right with NO LEAKS. What I did what get as TIGHT as I could and then took out for ride up and down street to get pipe hot and then CRANK DOWN one more time. This got that last little pin hole leak to stop. The Clamp is really a good and strong and is meant to take a beaten, BUT it's all on how you position the clamp to the slots in the MUff. Hope it works out for you. Gar ;D

Okay this afternoon I rode around to a few places and got some news - the current clamp is not what originally came with that muffler.  The clamp in place now is beyond repair (heat weakened it - cannot tighten any more)
Then the HD dealer tried to sell me a HD....geeez, get a real bike dude.  ;)

A U clamp was tried, but it doesnt quite work. I am bidding on a new muffler on fleabay once I get an answer as to how loud it is.

And best news of all the afternoon stops - the local car muffler guys agreed to weld my muffler on for me for no charge!  :)

Go on back to the HD place, march right on past the salesman who said buy a real bike (fierce look, flip'em off if you want) go right back to the parts desk and ask for a take off from a dyna (no cross over).  Tell you're gonna beat it over the head of the salesman.  If he don't jump and grab you one, tell it's really for a project bike.  If'n you need to loosen him up a bit, ask him for p/n 710.  Black knob, with white letters.   ;D

Dude, no lie....I did that after work yesterday (before seeing your message) and here is what happened...

Upon arrival I asked for service/repair and ended up talking to the shop owner. I insisted the pipe I had on was a HD, despite the clear skeptisim from the service dept and owner.

He went out with me and looked at the bike ("is that a 250?" "no, a 650" "really?!") then at the muffler.  "ohh yeah, it says right on the pipe HD and an item number"...duh. ::)

Back into the stealership and he looks up the number. Its an 03 Dyna (no surprise). The surprise was this - he flat out refused to sell me one.

He said at first that he knew he had some "in the back" from people switching out to louder pipes, but then said he had no time to go looking for one. I looked around - the store is empty of customers. Like what - you're so busy you can't sell me a flipping pipe?!! >:(

He rudely told me that my bike was running lean (like I dont know this!?), and if I put a new pipe on, it would turn blue, so why did I want to bother with a new pipe...Ummm maybe because I want to replace the banged up one with a wrecked clamp that keeps FALLING OFF??!!

Then he said I had to re-jet before putting on a new muffler, and his dealership does not do metric, and he cannot recommend anyone who would re-jet. WTF!??  Did I say I wanted you to re-jet my bike? All I want is a fricking PIPE!!! >:(
RUN AWAY!!!!!!

I went down the street to the Suzuki stealership, knowing before I even went in that this was going to be interesting. They had no mufflers at all. They did find a muff clamp in the catalog, then told me it would be $290 to re-jet my bike. I am so in the wrong business. ::)

End result:
- I still have a dinged up HD dyna muffler halfway attached to my header
- No one in town wants to sell me Dyna
- I am watching a Dyna on fleabay. If I get it, I'll have it welded on.
- I am still fairly pissed off  :P

Why is it that one little project turns into a major production twice as long and four times as expensive?

OK, the direct tact is the wrong course.

Seems like many of the shop owners use to be salesmen.    They're too much into money and prestige to understand the fun and satisfaction of wrenching.   The Mechanic-owners tend to NOT put up with the politics of running a big dealer  :(

Here's some come backs to those guys :

To the Harley dealer:
to his "dealership does not do metric", reply   "What?... oh yea... this is a Harley dealer, you don't do modern stuff!"

to his : " no time to go looking for one",  reply "Yea.... I guess you make so much money selling accessories for these boats that you can leave inventory lay around."    

to his "he cannot recommend anyone who would re-jet" ,   reply  "I don't own a Harley,  my bike is easy to work on."  

to his "is that a 250? no, a 650, really?!",   reply  "yea,   it's horse power to weight ratio is better than most Harleys "   (note: don't tell him that the 5 gear should be a little taller, he doesn't need to know).

To the Suzuki dealer:
to the " $290 to re-jet my bike", reply "this aint' no Hayabusa, there's only one carb and you can take the bowel off without taking any covers off"

I was treated the same way when I was looking for a Sportster pipe for my bike.

Me: "Hi.  I need a Sportser pipe"
Them: "What year?"
Me: "Doesn't matter.  I just need one without the crossover hose"
Them: "What year?"
Me: "2004"
Them: "XL? Custom?"
Me: "Uh, no. Its for a Suzuki"
Them: "grunt"
Me: "Excuse me?"
Them: "We don't sell stuff for metrics."
Me: "All I want is the pipe.  Can you sell me the pipe if I promise Not to put it on a metric?"
Them: "No, you ride a ricer.  We don't sell stuff for ricers."
Me: "Okay then..."

Left the store.  Empty handed and determined NEVER to place my arse on any Harley, so help me GOD.

The attitude of those people is un-freaking beleivable!

Anyway, Skatnbc...  I have a second HD sportster muff that I won off of ebay.  It does have the cross-over hose, but I had the muffler shop that welded its twin (I won 2) onto my header also weld a freeze plug over the hose fitting.  No leaks and its in the back of the muffler so you don't see it.

If you're interested, I can finish grinding the tube down (inside where the cross-over connection would go) so it fits over the Savage header.  Once thats done, its just a matter of having the plug welded in place and then welding it to the header.  Let me know and we can work something out....

If I get around to changing my exhaust, I'm going down to the John Deere dealership.   No kidding.  If I can find one that will fit, I just might try it out.  I like the sound of those things.  Especially the old one and two cylinder John Deere poppers.  I'll bet it would be the only bike around that sounded like it should be out baling hay.

Of course, I got over my fear of being laughed at some years ago.  This idea might not be for everyone.

Finally got the new Dyna muffler on, and today took it to the welder. We had a think on it while it was cooling off, and decided to try something different.

Instead of welding, we cut off 1/4" of the end of the header pipe so the Dyna pipe FINALLY fits flush with the ring like its supposed to.  
Clamped it down and it works like a champ....even backfires still when I want it to! Yahoo!  :D

Post by Max_Morley on 05/27/08 at 18:03:11

Had to do that on the SuperTrapp that I gave Sluggo when we fitted it up. Seems to be some variation in the amount the inner pipe protrudes past the ring that seals the inner and outer pipes. His is a newer model than the 96 I bought it for and it worked fine on mine. I just ended up going another way at the time. Still have an Aluminum Honda 500 version of a Trapp sitting in a box for when this HD one dies, assuming it will in time like the first 1/2 of the pair did. IMHO the one that fits the easier is the HD FXD/F (I think that is Dyna Wide Glide model, stacked mufflers on the RH side like a sportster, and with the almost 1300cc engine which makes the flow rate correct for our 650 cc ) version as it is slotted for the mount and a carriage bolt work well.

Ya know - we should have that as an option for muffler install in the tech section - cutting the header pipe a bit if all else fails.  

It only took a minute with a sawz-all, took off just 1/4 inch, and I am very happy with the results.

Include how using a grinder to shorten the header can be hazardous. The sparks past the battery vent tube can ( & WILL) ignite the hydrogen, popping the battery case. You KNOW how I know this..

Dang!  I totally forgot about that - and we were zipping a few little sparks! Thankfully hardly any because the blade kept getting too hot and we had to stop often.

Definitely worth mentioning and noting for future use!  :o
