Title: Muffler Mod
Post by mscepu101 on 05/24/11 at 14:41:32

Help!

I just purchased a "stock" muffler from someone on this website and it arrived with the baffle removed.

I am very disappointed but willing to try and work with it.  

Does anyone have an idea if an older baffle can be removed (without difficulty) from another muffler an inserted into another muffler.

The muffler on my savage was damaged when I layed it down and I wanted to get it back to stock condition.  The internals of the muffler has no issues.

Does anyone know if I install the muffler without the baffle will I have to rejet?

R,

J

Put a post in the marketplace section of this forum. Folks are routinely changing out the stock muffler and you may get one for the price of shipping.  DONT pay big bucks for a stock muffler.   8-)

Since you stated that you wanted a muff not mod'd (drilled out) I would be very disappointed too, especially if he did not disclose it.

Swapping baffles would at least require a welder and I would rate it difficult.

If you're running stickly stocks jets, yes I would say you need to rejet.  But I would say that you would need to rejet even if you left it stock.   8-)

Oh boy!
You have me thinking!

Why would I need to rejet if I put on a stock muffler as a replacement?

Because it's too lean stock, unless you're at 10,000 feet.  I'm at 6,000, and had to remove half the spacer on the needle, and richen the main jet, and the pilot jet coule probably stand changing to a larger size, too.  It ran like crap with stock jetting, backfiring merrily along.  
Why not forget the stock muffler and get a Dyna muffler cheap off eBay, 80 decibels stock.  I don't like loud bikes, but I like them to run well, and the Dyna is just fine for me and a lot of folks on this site.

The world is a big place.  The altitude goes from sea level to mile high denver and beyond.  What works great for me will be too rich/lean for someone else.

I liked 150 jet with a stock muff.  your gutted muff may take a 160.

I think I have both baffles from mine around here. The small baffle was held in by a screw wedging it in. The large one slid out about 6" as I was going down the road, so I just pulled it out. Mine didn't run right at all without them. It shouldn't be too hard to put them back or get someone else to. I think they'll fit in one of those $10 to anywhere Postal boxes. Pm me if you want them, or the whole muffler, but it has acouple of 1/4" holes in the end. It also has a couple of stains on it that I cannot get out. Not bad but they are there and the heat shield. Whatever you need.

Sorry man, I found the baffles. Didn't look at them when I yanked 'em because they were hot. It looks like they are too short for stock.  While it was quiet when I got it they have definitely been cut. I have a Harley quiet muffler number 65842-07. HARFXS 1584. Sorry to get your hopes up. :-[

All this talk about rejetting with the stock pipe really floors me, I live at about 2500 feet and ride between home and about 3500. My 09 California bike is stock except for a OEM type K&N and 2.5 turns out on the pilot screw. It runs great, rarely makes a little putt at shutdown, has plenty of power (for a 650cc) all the way through the power range. I also own and ride a 900cc Kawasaki and I can tell you this little Suzuki is not only my favorite bike but runs stronger to about 70mph than any other bike I've owned. I can only imagine the power and speed you guys must be getting,but I'm almost 60 years old and don't want to go much over about 70 on any bike or car for that matter so I'll just leave mine alone.

at 2500 the jets are about perfect, more or less what I said.

I have a 2009 stock muffler that is sitting around if you'd be interested?  It has about 1000 miles on it I believe.

I'll keep saying it, rejet because you need to, not because you read that others have done it.
At 800 ft elevation, my stocker w/ drilled exhaust runs perfect w/ the stock 145 main jet. But I did have to do a 1/2 spacer mod to richen the low-mid end a little. I did it because it needed it.
I have a perfect idle, so I don't even think about removing the plug over the mix screw. Backfire ?? Learn to live w/ it,......you may lessen it a little by hacking it, but it will always be there. If mine ever quits backfiring, I'll get it fixed.

From all I've read, 1/2 the carb problems here are cause by hacking,......when most times there was no need to do so.

All IMO only !

We have the same elevation. I have an '06. All jets stock, but I reduced the spacer for the same reason you did. My muffler is stock with the baffle out. Actually that didn't make a real difference in performance without the baffle, except higher rpm seemed to breathe a bit better. There's still two plates deep inside the muffler that IMHO are actually taking care of the require back pressure, and the baffle behind it was just for noise reduction mainly. But I did need to turn the mixture screw out about 2 1/4 turns to make the low throttle and idle running decent. Then I de-snorkled the air box and took the lid off and got a new stock air filter. That made it run too lean at WOT with the stock 145 main, so I put in a 150 main. Before the exhaust turned really light gray to whitish, meaning it was too lean. The spark plug looked about the same. With the 150 main it's more like a nice tan color, both the plug and the exhaust. The pilot circuit runs fine on the 52.5 stock jet. I tried a 55 pilot jet, but then i got black smoke and it ran like the choke was pulled half way all the time. So I put in a 52.5 pilot jet with bleed holes, and that helped with having a little smoother throttle response between 0-1/4 throttle. With the stock 52.5 it was more like an on/off switch in slow corners. That made it a little scary when sand or small gravel was on the road.

I cannot believe all the useful info I get from this site!

This site keeps me inspired to take care of my 99 Savage and keep it running as long as I can!
