Title: Fuel mpg Post by MMRanch on 06/05/21 at 21:43:10 I started keeping track of Kate's (W650) mpg after our Texas ride . Now remember Kate is a under-bore machine with only a 72mm bore - but - a 83mm stroke. So its really easy on fuel. The last tank of fuel was 93 octane of real 100%Gas. got me 64.48mpg. I was in shock/denial --- So , I reset the Garmin Trip set to check the odometer on the bike . Well , the bike showed 17.8 miles while the GPS showed 18.3 miles on the way home from todays outing - so actual mpg would be even higher by a little. The tank full before that was 89 octane of E-10 that got 59 mpg. I've been trying to get that kind of mpg from my S-40 for years but haven't ever got more than the high 50's. Is anybody else doing better ? |

Title: Re: Fuel mpg Post by Dave on 06/06/21 at 03:46:58 If I ride my Cafe' bike nice and gentle - I can get up into the mid 60's. On rides in the mountains playing Hooligan I have gotten as little as 48mpg. I have a Wiseco piston, tall gearing and the bike is light. You have a windshield and saddlebags - those are very likely going to reduce the mpg as the wind resistance is increased. |

Title: Re: Fuel mpg Post by DragBikeMike on 06/06/21 at 15:14:21 MMRanch, sounds like that big Kawasaki is running real good. Do you happen to know how much it weighs? The bore/stroke (87%) is interesting. Reminds me a bit of a Harley (Big Twin Evo is 3.5 x 4.25 or 82%). Does it have carburetors or is it injected? Regarding the LS fuel mileage, I've started to keep track of it for my projects. All stock I get about 55mpg. With a free flowing airbox and exhaust I've been running about 65mpg. With Lancer's souped up flat-top piston and a bunch of mods it routinely yields low 70s, usually about 72mpg. That piston really gets the job done. |

Title: Re: Fuel mpg Post by MMRanch on 06/06/21 at 20:51:22 that big Kawasaki ;D It totals 676cc , and is lean running . The EPA would "LOVE" me ! ::) If Kate was any leaner it might lope down the road like a horse. Its carbureted (34mm-?) with CV's * 2 and four valves per cylinder . Its the 2000 W650 , I recused it from a barn last fall. So How do I get my S-40 over 60 mpg ? :-? If I take the air box out and put a air breather on like this one. A pair of these are on Kate now , I got tired of taking the air box out every-time to tweak the carburates What about keeping the noise low and having a free muffler , any good ideas ? |

Step 1 - Remove the windshield and saddlebags. Those are displacing a lot of wind. (Just kidding as I know this is a touring bike......however those items do have a big effect on the mpg you can achieve). Step 2 - Read DragBikeMikes muffler thread. You currently have a baffle in a very small pipe - I am sure it is restrictive. DragBikeMikes best muffler had a perforated pipe inside a glass pack. The perforated pipe has good flow and minimal resistance - the glass pack soaks up the noise. The parts to build this are pretty cheap. You have a lathe and welder and you could make this muffler easily. http://suzukisavage.com/cgi-bin/YaBB.pl?num=1609379913 https://www.ebay.com/itm/203354099219?_trkparms=ispr%3D1&hash=item2f58d94e13:g:iX4AAOSw569gfoGm&amdata=enc%3AAQAFAAACgBaobrjLl8XobRIiIML1V4Imu%252Fn%252BzU5L90Z278x5ickkrmmq8hWevtuKE7%252F%252BLfVXtnDIx8lWtE%252B2URw7WXwDBBkHZ2vlMMe4VmOFdho%252FUJ4rjn5NdRQdeULHJuaF8hWpzdnhRhYmOpii1hmJHdDYD7wlM453wmSBioYIjqfV3NdnpFPKXpvi2u38jvNAip1JUzubTbHMte6mCXKhtNGpxr7vmRawtiijLhMoHqeTP%252B4%252BYH8IKVGA4iOwYyfi5bxYozP3qgBKdrYNBudRiFPP8VJ1PNF45aY0irLsAKBt555ph90fvtjDKlDUyvBySC3s7VCMfYgMde0OgtMHqOTEh5rFhvU9rKfxWdd6PKOkr6r4%252FndmE2DQgHECShhWyqhhi%252B7blLH%252FABObaMbfCDLGUloAKgh9qW0Q4Kjx42PSmmoowwUkMYrPMYPlthyQVsiYZerHwLU34XuQRspwQz6PpyPv8ehdMPJRQh5DMwU%252BCKUkmbLCMxyzmbtvkP1Z7YyyBttvdicB9OuQ7XF%252Fx1p7bg0q%252FhL03ldiKnzoAwigghELwyniS2HLCjyi8Py4LoUEMeCGygW86p7%252Fa2q6oxRemHny1cRC3HajJNV237MG3tp2A%252FbbZ3UuKyM%252BULPOn64bgOA4az%252Bq5L%252Bmpza%252F1hIz04iwd%252FbbPYrv%252B7qJM7BudGeENIM5TbC6VTdNazJZNZeOU%252FsYJZnUZsjR2C0KqQ6rAtuLyx3SPEYjorg4oJOk2mKg52pEnFi0ey%252BAtJO3KgcpkhKJheQwCv1MXtYgPSBKJzEqmLQNT%252ByHjbq8s3GcTeZkTZMqNJHWxVSSUJTbjotI%252F6hArJSTGeFF7OrMJ3Ve%252BRs%253D%7Ccksum%3A2033540992194f94714d5ddd4db78f9af72b2ed15cc4%7Campid%3APL_CLK%7Cclp%3A2334524 Step 3 - Try jetting your carb. I have spent many hours riding behind your bike, and my sense of smell has never detected an overly rich fuel mixture (I have ridden behind a few poorly jetted Savage motorcycles and I can smell the rich exhaust). I believe the slide needle setting is the most important for achieving good mpg during steady cruising......try lowering your needle a little bit after you get a better muffler installed. Step 5 - Get a new and improved Wiseco piston! The things that improve performance and acceleration are not always related to the mpg while cruising. The needed flow while running at wide open throttle may be drastically different at partial throttle when you are running far less air through the engine. A piston however can make for an improvement that works at any rpm or throttle setting. Step 5 - Lower your expectations! If I ride my Savage with a bunch of old fellows who never pass a car, always ride 10 mph below the speed limit and slow down for every corner - I can get over 60 mpg on my Cafe Savage. The bike has a high compression Wiseco and I have used an Oxygen sensor to jet the carb.....I know I am running with a good fuel/air mixture. My fuel injected bikes with windshields and saddlebags show around 55mpg - they are using the fuel properly and the air resistance just doesn't provide for a way to get better mpg (unless I ride really slowly).....I think that 55mpg is a reasonable for a bike with a windshield and luggage and riding at the speed limits. |

Title: Re: Fuel mpg Post by MMRanch on 06/07/21 at 09:35:03 OK Thanks Dave and DragBikeMike , I'm ordering this 2" muffler .

Title: Re: Fuel mpg Post by sjaskow - FSO on 06/07/21 at 11:33:35 In looking over my Fuelly history for the S40: https://www.fuelly.com/motorcycle/suzuki/s40_boulevard/2006/sjaskow/19052, it appears that most of my 60+ MPG tanks were on trips on two-lanes where the speed limit was 55 or under. If I did 4-lanes or interstate, high 40s weren't that uncommon. |

Mike: In order to quiet it down - you need to be able to insert a perforated pipe inside the glasspack. Just having a glass pack without the center core will guarantee is will be loud. DragBikeMike used a 2.5" inside diameter and proved it works...you have reduced the ID to 2" - that doesn't give you much room for the perforated core. I have some 1.5" perforated core I can send you. Do you want me to weld the center blocking plate into the core before I mail it....or do you want to do that? |

Title: Re: Fuel mpg Post by MMRanch on 06/07/21 at 22:17:05 Hay thanks Dave ! I've got some of that SS stock , but mine is a flat sheet. The guts in my 12" shorty is set-up like the diagram (some what). Its got a 1.25" going from the header into the muffler 80% through - solid block with 1/8" bleed holes for 2" then a 2" solid pickup forcing the gas to do a 180 deg. , to the start of the 2.5" dia. where it gets the full dia. of the muffler to reverse directions again and go to the exit.. That center 1.25" pipe must glow red when the throttle is open ! ;D I'm sure the 12" shorty I'm using now has some back-pressure at open throttle but very little back pressure at normal throttle. It got 56 mpg on todays fill up after putt-putt-ing around at +-50/60mph with 89 mid grade E10%. I'm thinking the motor was designed when 89% was normal regular and mine works good on it. But we have to want more all the time ! :) I'm trying to get away from a solid block in the middle of the muffler if possible ? So , let me get back with ya on the insert after a trial week of just muffler. If it does need a solid block in the middle then what do ya think about a 1/2 length SS mesh gas pick-up coming from the rear that is a loose fit inside the muffler guts with a 50-70% block in mid pipe. I'm going on assuming the gasses are cooler/smaller at the rear of the muffler than the front of the muffler. From making my own muffler guts , I've found that a big group of 1/8" holes are quieter than a few 1/4" holes , and that mid muffler blocks are quiet without the hole in the washer. something like this coming from the rear of the muffler , but longer/bigger dia. with smaller holes. |

Title: Re: Fuel mpg Post by Dave on 06/08/21 at 03:01:26 Mike: What you are basically doing is the back half of the DragBikeMuffler. It might work - I am not sue how durable it will be if the front of the inner pipe/baffle is not supported. Those small baffle inserts you show will create a lot of back pressure - you need a lot of holes to get the exhaust flow of big single moving through without creating a lot of pressure. |

Title: Re: Fuel mpg Post by MMRanch on 06/08/21 at 07:27:29 You know exaust flow can be a fickled thing to deal with . On that HD 883 I had the factory rear muffler stopped up when the muffler guts melted in the front part . So I put a pair of 12" shorties on it. They were quiet with only the factory guts in them. That same muffler on the S-40 w/factory guts is crazy loud ! :-[ Sometimes Ya , just don't know till ya try ! :) I wonder if the smaller exit hole had anything to do with it ? A exit the same dia. as the inside of the header would be free flowing. The gases are cooler at exit so maybe even a little smaller exit would be OK. ? :-/ Remember seeing the "Fish-Tail" muffler exits . ;D I could do a down-turn exit and bounce the noise off the road for the world to hear ! and keep the rain out too :-? ....................... Those small baffle inserts you show will create a lot of back pressure Dave , I can make my own with the same size dia. pickup pipe as the inside of the header pipe , and use steel instead of tin. 8-) I hope the muffler with a down turn will be quiet and free flowing enough ? |

Title: Re: Fuel mpg Post by DragBikeMike on 06/08/21 at 10:59:38 MMRanch, the Northeastern muffler you show is too small. Once you put a baffle inside it will be too restrictive. It uses a louvered core which reduces the inside diameter by at least 1/4", possibly 1/2". You need a 1.75" baffle tube to achieve maximum flow. That would be 1.75" OD, 1.65" ID. The area of the cross section outside of the baffle has to be close to the area of the cross section inside of the baffle. I suggest you try and follow the design I came up with. Use a 2-1/2" muffler with a perforated core, not a louvered core. Thrush offers stainless steel glasspacks, and that LCGP unit is fine too. I bet Walker also has a good stainless steel glasspack selection. Just make sure the core is perforated, not louvered. The Northeastern length is also too short. You really want to use a muffler long enough to accommodate a baffle tube with 216 holes (108 each side of the center plug). The holes should be 11/64" diameter. If you stick to that number of holes, and that hole diameter, you will achieve maximum flow with minimum noise. I spent a lot of time testing and evaluating that LCGP muffler. Made two versions, one with a 1.5" baffle and one with a 1.75 inch baffle. Did a bunch of flow tests with my home-brew bench. The 1.5" version was good but the 1.75" was a lot better. The final version works really good and it's very quiet. It absolutely yields improved performance, both acceleration and economy. I just recently tested it with a stock header pipe on a stock engine and it yielded an 8 mpg improvement, and lots more performance in the acceleration category. It sounds really good too. Looks to me like you have all the tools you need to make a sweet muffler. It's an easy job with a lathe and a welder. Go for it. |

Title: Re: Fuel mpg Post by MMRanch on 06/08/21 at 18:10:05 Thanks for the reply DragBikeMike . I did change my order to the 18" + ends version and if I can leave it open (see-through) then all is well with no restriction at all . I've made the same design as your using a 12" shorty muffler with a 1.25"-ID. middle pipe and white fiberglass 1" wrap in the large dia. muffler area . They are quiet . The white wrap don't last long enough. But the Factory Glass pack would solve that ! :) Did ya ever figure out where the idea of a little back-pressure is good comes from ? If I need to make it more quiet then I'll cross that bridge when I get to it , but like the wise + smiley Versey said : That's a '400' vs a '650' with the same muf. maybe you have to increase the muf by a third to get the same results? so 18" instead of a 12"? It will be here in a week . :) |

Looks like you're getting plenty of feedback from much more knowledgeable folk, but I did want to comment on your data. If I'm reading your MPG correctly, E-0 (pure gas) netted you 64.48 and E-10 was 59. Were both tanks similar riding? The same speedo/odo error (looks around 3%, which isn't bad) would be on both tanks. If those were similar riding conditions, and my math is right, E-0 netted you about 9.5% better mileage. That's pretty amazing, interesting, but not totally shocking considering the industry "narrative" sticks with 3%. This makes me really eager to find out my switch and tracking (started today) will work out. In addition to the mods suggested, perhaps also switching to E-0 will put you over the top. |

Title: Re: Fuel mpg Post by Dave on 06/23/21 at 11:43:17 MM: I got to thinking about your mpg issue. I wonder if you are still using 20W-50 and then adding STP? That thick mixture could be creating a lot of drag inside your engine. The ball and roller bearings likely don't care much - but the cam bearings, piston/cylinder and oil pump are likely causing you some losses in HP and MPG. Enough to make a noticeable difference - I don't know....but I suspect that the reason a lot of modern cars are going to thinner oils is to allow them to increase their MPG numbers. Why don't you try using the 5W-40 Rotella T-6 next time without adding the STP? Youzguyz has proven that you don't need any "thickeners" to get high mileage out of a Savage engine. |

Title: Re: Fuel mpg Post by MMRanch on 06/23/21 at 21:32:07 Dave - You may be on to something. How about the Zinc for the tappets ? The Guzzi just rolled over 20K-miles and its time to change oil. The manufacturer recommends 20w-60 , and I could put 10w-40 . I'm more likely to play experiment with the Savage. :) ..................... I've got so much to do for the next month , I may be a while getting back to changing mufflers. The hay cutter tore-up 10 days ago and I just got parts for it today. The property next door came up for sale and our loan officer led us around for 2 month then quit working for the bank - leaving us without anything -- so we're having to start over with out all the paperwork being returned ! The sellers of the land are growing impatient and I don't blame them. I'm shopping for a new hay cutter and there ain't anything but the really big dollar stuff left. I ordered a carport kit ... its been here a week waiting for me to find my round-to-it. There are numerous holes in the fence up on the hill in the woods and the calves are getting to the exploring stage of life. And its ridding season so I want to take a ride everyday ! The muffler may just have to wait a while ? ::) |

Title: Re: Fuel mpg Post by Dave on 06/24/21 at 03:49:42 MM: I would use whatever Suzuki or Moto Guzzi (or Honda or Chevrolet recommends you to use). They designed the engine to work with a specific range of viscosity. If Moto Guzzi recommends 20W-60 - then the inside of their engine has clearances that require that oil viscosity.......if the builder wants 0W-20 you know the clearances are much tighter and designed to work with the thinner oil. Adding STP changes the viscosity and you no longer have what the manufacturer designed for. Rotella T has enough ZDDP for the Savage and currently you don't need to add any additional ZDDP. Youzguyz is still running his original cam and rockers at 212,000 miles, and I don't believe he has ever added supplemental ZDDP. A few years ago the forum's experimented with adding ZDDP turned out to be a bit of overkill and unnecessary with a proper oil - and the Redline ZDDP was costly and it would get a pink sludge in the bottom of the bottle soon after it was opened. Once the pink sludge formed in the bottle we had no idea if you could still get any benefits from adding it. When you use an oil with 1,000 ppm or more of ZDDP you don't need to add any additional ZDDP. Rotella and Mobil 1 have proven to be good oils in the Savage and they don't need any additives (STP or ZDDP). https://www.mobil.com/en/lubricants/for-personal-vehicles/auto-care/all-about-oil/ask-our-auto-experts/mixing-motor-oil-to-reach-the-right-zddp-level-for-classic-cars I have attached the chart for the LS650 oil viscosity that Suzuki recommends. There are a lot of options and although they are all listed - that doesn't mean they will all perform identically. The 20W-50 is listed - but it will be thicker and require more energy from the engine. I would stick with the recommended 20W-60 in the Guzzi, and use a 15W-40 or 5W-40 oil in the Savage. (The 5W number being smaller than the 15W is actually a good thing - as that value shows the oil will allow the engine to start easier when it is 32 degrees......while the viscosity at operating temperature (212 degrees) is the same 40 weight). |

Title: Re: Fuel mpg Post by SCS40 on 06/24/21 at 04:21:58 Well darn. I saw the post on oil recommendations and additives and just went with Redline. I guess I’ll be short changing to M1. :/ |
|
Title: Re: Fuel mpg Post by MMRanch on 06/24/21 at 06:32:10 Just looking at the information , it would be logical to only use 10w50. But You say 10w30 would be better and easier for the engine to pump around ? |
|
Title: Re: Fuel mpg Post by Oldfeller--FSO on 06/24/21 at 07:11:06 Rotella 5w40 is ideal if you want a full synthetic that has enough ZDDP in it. Remember, the full synthetics do not thin down with heat like a dino oil will do. If you prefer dino oil Rotella 15w40 with enough ZDDP in it is your huckleberry ...... Both kinds of Rotella are sold at your local Walmart. Please don't get confused when people are talking to MM, he runs MotoGuzzi's that use antique Italian oil ratings and he likes his odd oil treatments to go with it. |

10W-30 is only recommended up to 86 degrees - you and I often ride when it is up into the 90's. 10W-50 is going to get you back into the oil that is thick......yes you can use it - but it is not necessary to use an oil that stays that thick. I keep suggesting 5W-40 or 15W-40! |

Title: Re: Fuel mpg Post by MMRanch on 06/24/21 at 13:05:14 So , I need to give 5w40 a try and see if the MPG goes up.

Title: Re: Fuel mpg Post by MMRanch on 06/28/21 at 21:01:02 Hay , I tried that new muffler to day. I was really surprised how quiet it is ! It is 18" long , made of stainless steel , the hole is 1.25" strait through for zero back pressure. It has a 2 inch ends on it and a 3.5 inch body . It also gets too close to the rear foot peg ... so ... I'm getting the 3 inch body model and putting a heat shield on it. I would have expected a lot more noise , but like Versey said : refering to the 12' mufflers on the 883 sportster That's a '400' vs a '650' with the same muf. maybe you have to increase the muffer by a third to get the same results? ................. I just ordered the 1.75" version of the same muffler 18 inches long , the hole in the middle can be one inch and still zero back pressure I think. It should be here in a week , I'll let ya'll know how it works . :) |

Or ... now that I have a big cutter to go with the big tractor and a fixed small cutter to go with the small tractor , I can have a friend over to cut hay with ! ;) I could have bought a new RE-Twin for a lot less ... come to think on it : Its more fun to ride motorcycles than tractors , just by a little ! :-/ I did get a dealers price , but I have to put it together myself but saved near $3,000 on it. |

Title: Re: Fuel mpg Post by MMRanch on 07/01/21 at 19:46:24 Oh yea , They say "Thank You" all the time but they have trouble with the pronunciation so it sounds like Moooo :) ......................................................................... Getting back to gas millage : I've got a muffler with the 1.75 inlet/outlet w/3" OD. ordered . I think it will be just fine with no obstruction to make back pressure . The larger one is too big around to pass under the passenger foot peg. I'm sure Marcia would be using it for a foot warmer . Anybody need a stainless steel 2" in/out x 3.5" dia x 18" + ends muffler ? |

Title: Re: Fuel mpg Post by MMRanch on 07/02/21 at 22:05:41 twist rate may be what makes it quiet ? That hole is more than an inch , might be 1.25 inch ? It will be Sunday afternoon before I get a chance to hear it . |

Title: Re: Fuel mpg Post by LANCER on 07/03/21 at 16:17:00 The muffler on Rex has a 1.5” central core just like yours with another larger spiral around that and it is LOUD. Your core is smaller so maybe that will reduced sound level a bit. |

Title: Re: Fuel mpg Post by MMRanch on 07/03/21 at 19:36:38 Hay Lancer I had a few minutes this evening so , I slipped the small (1.75") on to see what it sounded like . The smaller one was louder ! The larger one has more rolls of cups , the smaller one only has the seven rolls , the larger one has thirteen ! I'm thinking of playing with the exit hole size next or just fix a lower mounting fixture and use the larger diameter one ? :-/ Its nice to have a bike to ride while I experiment on another one. :) |

Title: Re: Fuel mpg Post by MMRanch on 07/05/21 at 23:11:10 Hay Versey , I took some 1000 grit sand paper and polished the SS muffler . This one is the 3"dia. one , the 3.5" is the same material but a little quieter for some reason ? |

Title: Re: Fuel mpg Post by MMRanch on 07/06/21 at 18:05:03 Hay without any back-pressure the LS650 pulls really STRONG ! :o I got everything together this afternoon after cutting this hay field. Here's a picture of both. The polishing on the new muffler looked really good till the heat from a 30 mile lap around the country block got things "WARMED-UP" a bit. Now its just the "RIGHT" shade of "YELLOW STRAW" but still sanded smooth as glass. :) This picture was on the way out the driveway but facing the house. ................................ Another thing occurred to me ! I have installed the 25 tooth front pulley and am running a 16" rear tire . So the odometer is not right or the speedometer either. I have ordered a GPS speedometer and should soon be comparing miles to miles ya might say. ;) It should be here by next week at this time. Maybe using know to be good data might make the MPG figures more "factual" , at least I'll be sure of where I'm at. The free flowing muffler and the higher gearing should return some high MPG numbers that are reliable. Now if I can get the nut between the seat and the handle bars to loosen up on the twist grip on the right handle bar I should get better MPG ??? ::) |
