Title: Think I found the hole!
Post by islandwahine on 10/16/07 at 16:01:13

Well I tried to "feel" today where the hole in the muffler might be. I started her op and felt around the area that had a bunch of soot (underneath the bike). I felt air hitting my hand and sprayed soap on it, sure enough, bubbles!
Just so you can see what we have to deal with here in Hawaii, a picture of my unsightly muffler.

I think this bike was dropped at some point, or hit a high speed bump. Look where the bracket is bent, and poking into the muffler pipe. I think that's where the culprit is. What do you think?
How am I going to get that straightened out? I'm going to have to bend the metal piece just to get to the bolt.
this is going to require lots of liquid wrench!

Small chisel & a 1 pound hammer, drive the bent piece off of the head of the bolt far enough to get a socket on. You may be able to get something longer, like a pry bar on there, I dunno. I like hallering on longer things, it gives my fingers time to retreat if I mess up with the hammer. Yea, the fact it's been smacked is part of the problem. Most likely, anyway.

The air you're feeling is coming form the slots in the end of the muffler, bad gasket thing/doughnut.  That is if yo have the OEM muffler.

I think clamp most likely is history.  Trying to save it may need more banging than the muffler could handle.

 I think a dremel and cut-off wheel would be a good choice.  Get the strap almost cut thru and then a small screwdriver to break the remaining metal.

Is the strap an OEM part, or can I get a muffler clamp from the auto part store?

Start with WD40 when it is cold.  Liberally.  Wait a long while.

Try to bend if off the bolt head (as mentioned) and get a socket on it and loosen it...

Could get a torch involved too to loosen it up but you might need help with that....T-Mack mentioned a Dremel.  Yep.  Be careful.

Somebody was leaning good on that side, eh?  Or was it a speed bump?  Or climbing a volcano?

I think if it had been a volcano the muffler might have actually looked fascinating!

Well, you can look at it like this...that rust is in the best possible place.  Out of sight :P

Before any grinding, make sure the battery overflow is either plugged or isolated.  Or remove battery entirely.

Sparks can ignite battery fumes which are hydrogen.

Don't want to see explode the battery.

Gee, I can't believe I forgot to ment ion that little detail. Good call, cuz I popped mine..it was pretty spectacular, too.

I ended up buying a pretty expensive battery when I got the bike, it doesn't have an overflow like the OEM one. But I'll disconnect the negative just for safety.

harleys use exhaust clamps like those, automotive type look more like "u" bolts. a chisel type tool, should be able persuade that bracket clear enough to get a socket on the bolt. i'd use a 1/2" drive ratchet, and plan on the bolt breaking, but your luck may be better than mine.

These folks seem to have most of what I've looked for in exhaust supplies (and a lot of other good stuff too).

I guess by seeing how many posts I've posted since the end of July, you can establish I've not been very lucky so far. In fact it's dawning on me that I bought a lemon! Still love her, but boy!!!! I'm just about ready to put her into a junkyard!
(nah, not really, but I am getting tired of fixing things).

Why do you call it a Lemon?  I'm thinking that it was just abused.

Now, did you feed that clamp some WD40?  It looks undernourished.

Might also be a good time to introduce it to an impact wrench and socket. You know the routine, introductions, a little WD 40, close contact, and you never know what may happen.

Seriously, WD 40 (or liquid wrench) and an impact wrench can remove a lot of bolts and nuts that you would never have dreamed could be removed. The shock of the impact wrench tends to break loose the rust in the threads without damaging the head of the bolt. If it breaks off, then problem also solved.

Some of these former Navy folks have some real answers to stuck/rusty bolts. Seems I saw wintergreen oil & Kroil oil mentioned. I found Kroil & used it. Works great. I like it better than WD 40 for penetrating oil.

Thanks everyone.
Got too busy with work so I haven't gotten to it yet.
Would have been nice to have an impact wrench. I did recently purchase a nice long solid wrench that you use to attach sockets to. I bought it and an 18mm socket so I can get the rear wheel adjusted. Earlier some of you guys suggested the reason my tire was getting scraped on the left side was because it was in crooked. I have not been able to get that bolt off. So now with this huge wrench that I can stand on and use my weight to get it of, I might actually be able to get the darn thing off. Hope that $25.00 bit of iron is gonna be worth its money!

That is called a "breaker bar" ;D

That's a very appropriate name for it! You can definitely break  something (or someone  :P ) with it! ;D

AND if you get a piece of pipe and slide it on the breaker bar, you can break even more things too.

Maybe we should have a "Glossary" topic in the tech section.  Might help clear up the meanings of "thingie" and "do-hickey" too. :P

For future reference when searching for exhaust leaks:

Disconnect the petcock vacuum line at the petcock.  Start the engine (it will run for a short time on the gas sitting in the float bowl).  Let the vacuum tube suck a little Sea Foam into the intake tract.

Shut 'er down.  Reconnect the vacuum line to the petcock.  Wait about five minutes.  Start 'er back up.  There will be lots of smoke coming out of the exhaust.  If you have an exhaust leak, you will see some smoke coming from the leaky area.  To help things along, you can partially plug the end of the exhaust pipe with a rag to try to force some smoky exhaust our of the leaky area.

IHTH someone!
