Title: Baffle Removal Post by lordzamize on 05/27/04 at 13:56:38 I have a 1997 Savage, and I want it to be louder. I was wondering if I can remove the baffle with out working about the back pressure. Can I drill out the rivits holding the baffle in place? Do I have to adjust the carb or anything after doing that? Z |

Title: Re: Baffle Removal Post by lordzamize on 06/01/04 at 07:38:29 Soooo, I guess no one has ever done this? Or have you? Just looking for some guidance. Z |

Title: Re: Baffle Removal Post by LondonThing-co-uk on 06/01/04 at 16:19:56 Had a listen to that.... Anyone know what it sounds like with only the down pipe alone, and no can at all? (for Americans i mean muffler, lol) ChrisF.. |

Title: Re: Baffle Removal Post by gitarzan on 06/01/04 at 17:35:15 Yes I do. When I put on the Harley muffler on mine, do you think for minute that I didn't start it up to see what it sounded like "raw"?

Title: Re: Baffle Removal Post by LondonThing-co-uk on 06/01/04 at 17:40:21 LOL, i would have done the same, but cant cos myne hasnt run in over 10 years, and iv been trying to get the thing together for the last 6 months! But then i did decide to Drastically mod and chop myne, befor i even got it running as a standard bike, Doh! And i havent got a muffler at all, just the down pipe, if it sounded reasonable, i was just going to put a turn out on the end...??? What does it sound like with the Harley muffler? |

Title: Re: Baffle Removal Post by Paul on 06/01/04 at 18:36:37 I have a harley muffler and it sounds great. I think it's pretty loud. I was told if i want to make it louder use a heat gun too hollow out the baffle. I get alot of comments on how good it sounds. |

Concur. It's quiet, but lower pitched than the stock muffler. It has a lot better low pitched resonance. Kind of a nice thumpa thumpa thumpa sound. And it's a good bit lighter in weight. At least 1/3 lighter, maybe half. I had an extension pipe made for mine: http://freepages.genealogy.rootsweb.com/~gitarzan/bike/pipe2.jpg There is a chrome heat shield covering the Zinc pipe now. I'm considering painting the zinc pipe with high heat black (or maybe orange) paint -the kind they paint manifolds with- and getting one of these over it: http://www.jpcycles.com/showimage.aspx?OID=af0c6f9b-77eb-4d33-bed0-d7c0a7b90c17&IW=200&IH=200 http://www.jpcycles.com/productgroup.aspx?GID=91ff6c5a-77d9-4448-8d6d-2d1df00d7895&cs=Harley |

Title: Re: Baffle Removal Post by lordzamize on 06/03/04 at 16:42:27 Can I change out the stock with a Harley muffler without having to rejet, worry about back pressure, ect? |
|
Title: Re: Baffle Removal Post by lordzamize on 06/10/04 at 04:48:40 Here is what I did... Rather then removing the baffle all together, or putting a HD muffler on, I just drilled two holes through the baffle plate, 5/16" wide. I didn't use the foot long bit as suggested before. It sounds great and does not seem to have any performance changes! ;D |

Funny, after riding around on it for a month it no longer seems to be very loud. I wonder if I went deaf? ??? |

Title: Re: Baffle Removal Post by Greg_650 on 07/03/04 at 04:02:02 I forget who's picture I was looking at, but someone has a blue header pipe on their Savage...well, actually quite a few people do. So... ...if you ask about the effect of removing baffles, drilling baffles, or completely removing the muffler on a stock late model Savage, all you need to do is think "blue". Bluing is not normal, especially when we are talking about a double walled exhaust header. Bluing is the result of running the engine hotter by leaning the fuel mixture or lowering back pressure. That is the effect, and if you don't want "blue", then you better think "jets" too. There can also be more serious impact from completely removing the muffler than simple hearing loss (a condition that I truely have). You also run the risk of burning the exhaust valves. BTW - with the mention of Jon D's site. Yes, he drilled out his exhaust, but now he has a SuperTrapp or Jardine installed. So maybe there IS a better way after all.... |

Title: Re: Baffle Removal Post by TheBabyDerp on 09/26/24 at 09:45:37 Well I am 20 years late. I was 4 at the time of this post, but I recently de-baffled mine with a circular saw drill bit. I forgot the size, I think it was about 1.75 to 2 inches. Worked perfectly. I honestly like the sound, but it does need to be rejetted. Backfires bad running super lean. It doesn't help that I am at sea level down here in Mobile. Once I rejet the bike, I may upload a video and post it. |

Title: Re: Baffle Removal Post by JOG on 09/26/24 at 10:10:51 Step one Get running Step two Tune it, get it running Right. Step three Make mods. If ya make mods before it's running Right ya can't know if it's needing jetted or what. |

Title: Re: Baffle Removal Post by TheBabyDerp on 09/27/24 at 09:13:32 I've never done an exhaust after tuning a vehicle. I've always tuned after the fact. The bike was going to need a rejet anyway given how lean they come from factory. I got a stage 1 kit from sixsigma. Currently restoring a boat so unfortunately the Suzuki is a secondary affair. |

Title: Re: Baffle Removal Post by ThumperPaul on 09/27/24 at 09:27:20 What’s in the stage 1 kit? A 50 pilot jet and 150 main jet should be the biggest jets you need. Narrow down the white spacer on the needle some or get a couple washers at the hardware store to replace the white spacer. I think 2 number 4 washers should do it. White spacer mod ---> https://suzukisavage.com/cgi-bin/YaBB.pl?num=1104205157/0 |

Title: Re: Baffle Removal Post by TheBabyDerp on 09/27/24 at 12:09:38 Not sure off the top of my head. I will check when I get home from work. I will read into the white spacer mod. I plan on doing a cam/piston upgrade down the line. I heard the Mikuni's were superior. Any thoughts on that? |

Title: Re: Baffle Removal Post by LANCER on 09/27/24 at 15:43:46 Did you receive genuine Mikuni jets and parts ? If not, that could be troublesome. |

Title: Re: Baffle Removal Post by ThumperPaul on 09/28/24 at 04:11:56 To Lancer’s point, you want genuine Mikuni jets for the stock CV carb or if you switch to a Mikuni VM36 slide carb. Lancer sells a VM36 carb kit and also genuine Mikuni jets for either carb. As well as his other goodies - hot cams and pistons. The 6sigma website is a bit of a black box. Even when I added the stage 1 kit to my cart (playing around with them), it didn’t tell me what I would get for $50+ bucks. No thanks. If you don’t want to buy through Lancer, you can buy genuine Mikuni jets from JetsRUs.com. They are like $5-$8 each and like $8 shipping. That’s much better than a $50 kit that you don’t know what you’re getting. They also have the “washer/spacers” for the needle, or you can get a half-dozen of the right sized washers at a hardware store for less than $1. The Mikuni VM36 is a great carb. Lancer and his followers can attest and he’s sold many to happy members. I like the VM36 a lot. I also like the Keihin PWK38 a lot. The biggest difference when running a slide carburetor is throttle response. DragBikeMike did a great “carburetor shootout” technical post comparing several carbs.

Title: Re: Baffle Removal Post by Ruttly on 09/28/24 at 09:21:08 Derp , The Mikuni VM36 or VM38 both are fantastic carbs. Easy to tune , easy to get jets and parts. Once tuned properly , it’s all throttle. You will wonder why you even bothered with the stock carb , that can be troublesome. 36mm for a stock engine & 38mm for a modded engine. It makes a huge difference in acceleration. The VM carb has been quite literally used on a million race bikes in the last 65 years. Why ? Because it works !! |

Title: Re: Baffle Removal Post by ThumperPaul on 09/28/24 at 10:46:35 Great testimonial, Ruttly! Where do you draw the line on stock vs modified? I think Lancer tried the 38mm with his hot rod and dropped down to the 36mm for better performance. My memory is bad, but I think it had to do with the velocity of the mixture through the intake valves into the motor or maybe it was better fuel atomization (or both). I’m toying with the idea of experimenting with a PWK36 instead of my PWK38. My bike is what I’d consider stock - just a UNI foam filter and Dyna muffler (no hardcore Stage 3 stuff like hot cam, hi-comp piston, bigger valves, porting, etc…). |

Title: Re: Baffle Removal Post by Ruttly on 09/30/24 at 10:47:31 Stock or modified would relate to engine internals. Carb and exhaust mods still stock. Porting , oversized bores & camshafts, etc , now your in the modified camp. I don’t build radical engines anymore. I build fun , forgiving & fast engines. My preference is the VM38 for my bike. It has some mods too. I have no experience with the PWK , but decades with the VM. For me a big single is satisfaction personified. My tracker is my daily , she has earned her nickname (The Healer). It’s not how is looks , she’s a looker , it’s about how she makes you feel. It’s my mental reset button , the difference of how you felt when you got on as to when you get off. 0 , zip , nada flat spots in acceleration , all throttle , idle to WOT , super linear , smooth , powerful and so so satisfying ! 8-) |

Title: Re: Baffle Removal Post by JOG on 10/01/24 at 22:33:42 I'm in favor of Baffle removal. I'd feel a lot better about it all if I wasn't baffled by what I'm watching. If it leans through corners it's got Healing properties. Having the Oomph to accelerate Out of a corner increases the rate of healing. Honing riding skills, reading Twist of the Wrist ,YouTube , learning how to use what it will do right up to Sphincter Clinch,, and if you're the Skilled rider I am, being able to use everything it can do is beyond what is going to happen. I guarantee you every gun I own is a more accurate Thing than I can be. And every bike I ever had was able to Do a lot more than I could ever get out of it. |

Title: Re: Baffle Removal Post by TheBabyDerp on 10/02/24 at 04:41:27 Sorry for the late reply. Thank you for the advice. I have the stock carb not the Mikuni. And I already have had the kit sitting around for a while, I have just been real busy with other projects. The boat restoration takes up so much time. Spent all weekend working just on the trailer. Whenever you order from 6sigma, they tailor it to your bike and elevation level and what not. And give a few extra jets to dial it in. I believe it has 48 through 50 pilots and 148 through 150 mains. Not sure off the top of my head. As of right now, I am getting the bike set up for comfort and light touring. Forwards, handlebars, backrest, luggage rack, windshield, suspension etc. on my radar. In the future, whenever I get around to doing a piston and cam, I will certainly upgrade to the Mikuni at the same time, but I have no idea how long that will be from now. Yes JOG, I agree about removing baffle. These bikes are just too quiet in stock form. In my defense, I'm used to Harley's and Supersports... Not exactly known for their quietness lol. Once I got into Sportsters I stopped caring about going above 70. lol |
