Whats the top speed everyones gotten on a savage modifications or not. im just curious i can get to about 80 before the engine sounds like itll blow and i slow down

I have gotten to 80mph but that is because that is as fast as I wanted to go. If I wanted to ride fast, I would have gotten a monkey on a football bike (aka crotchrocket)

With a jardene muffler, 150 main jet, 85mph,
I ran a tank of drag fuel through it once 110 octain ,better acceleration,but still the same top speed,  85mph.
There are some here that claim 100 mph, I think they have speedometer problems.

  Completely stock i went up to 80 that was fast enough on this bike,it was still pulling good,I would bet $1000 it will do 85,and $100 90 thats stock,It pulls quiet a bet better with the 150 high speed jet.I weight 165.

The Harbor Freeway runs at about 85 mph when the traffic is light.  MAC muffler, carb may or may not have been worked by P.O., I was keeping up with traffic but the speedometer was blurry from the vibration.

I have done 85 on the Super Slab a few times, but that's about all she got, stock. It's quite frightening actually, but invigurating at the same time. Quite a bit of vibration rendering the mirrors useless.

Why did I do it?
Because I could ;D

190lbs and 125kph wih throttle to to spare. 2088 stock.  This was passing on a 2 lane hiway. I would go faster if necessary when passing. The bike does 110kph comfotably which is just fine for me.
I have no need to be 1st at the crash site.

Post by seviersavage on 11/10/08 at 19:12:12

When I first got my bike, completely stock except for jardine muffler,
(read no backpressure and way to lean) 80 was top speed.

Now I have rejetted and added K&N filter and went to a dyna (some backpressure yet more open than stock).

On the freeway yesterday, I hit 80 quickly, had 40 percent throttle left-
I backed off because it felt like it was floating, fast enough for me.

I bet it would go high 80's like it is now, possibly 90 with a smaller rider. Also I know my speedo is off a little due to oversized tire.

With a K&N and a Dyna muffler No other mods you'll be running way lean.    Rejetting carb will ,working in concert with those two mods help your top speed.

I've tapped 85 mph once then eased back down. I had a little more throttle left to go but didn't do it.. Flat straight road and a stock 05 S-40 i'm 225lb

Yeah the mirrors are just a blurr what with all the vibration and 85 seems really fast when I almost outweigh what i'm driving. lol

A lambda sensor on a Savage?  With a carb?  Is he just using it with a data logger to record exhaust levels?

164kph/102mph is quite believable with those mods- is that measured true speed, or indicated?
That aside, do you know what he's done with his clutch to take the power from those mods?

He ran a a/f meter for a while to sort out the fuelling. He said there was no way to get decent fuelling with the airbox so he removed it. 164 kph is either with well calibrated Sigma or GPS. It bumps into the hard limiter, shows rich (no spark) until 158 kph when it fires up again. I need to contact him about the clutch but I don't think there's anything out of ordinary there, stock components I suppose.

I have an 05 S40 with a 155 main jet, airbox door removed, k & n drop in filter.  I weigh about 215 or so.  On the flat in Arizona whether it be 100 degrees or 60 degrees, I can consistently do 95 and if I have a decent length flat can get up to about 100 or so within a mile and a half.

I have had a friend in a car drive behind me and verify the speed was accurate.  When my bike was stock, it did 85 mph before it stopped but had half throttle or so left.  I think I just got lucky with a bike that has more power as they are all a little different when built.

I am sure glad that with my mods I can get to 95 or so because some people on here have the same mods and more and can't get there.  I do not understand why that would be?

I think your friends car is off as well your bike,unless you have a chain drive conversion,there is no way a Savage will do a 100.

With proper gearing and mods a John Deere riding lawnmower can do 100 mph eventually  ;)

No doubt a Savage could be modded to get there.  I'd think that a stock bike will surely top out around 85-90 mph. Seems like there could be two different threads here:

1) Best way to mod a Savage to run 100 mph
2) Top speed for a 170 lb rider on a stock savage at sea level on a flat road.

The fastest I ever cared to go was 80.  (70mph speed limit in W.Va, so I was not far over the limit).

At that speed the bike is pretty much maxed out.  If the vibrations don't get you, the screaming of the engine will......

That's odd, a windshield usualy improves top speed,if it's put on right,
less wind resistance going over a smooth wind shield than all the nooks and crannies of the human form.

Unless you're scrunched down, in which case you'll be getting less wind drag.  My 100cc '67 TwinJet hit 65mph on the Davidson Freeway.

Mick,

I thought I'd be more aerodynamic as well, so I was disappointed to find that 80 was the top speed. I believe it's properly installed too, there's no wobble and my helmet isn't being rattled by wind. I did find a gain in gas mileage which is nice though.

I neglected to mention I was riding in a tucked position when I hit 90 mph.

How about the magic TON though,I dare say my steed will do a bit more than 85 if I had a longer straightaway,one great thing about our Savage, hills don't seem to bother it.
I googled Savage performance figures ,non of them gave top speed ,
but one of listed 16.? seconds in a 1/4 mile 77.? mph,shoot that's almost as good as my B/in laws drag pick up truck.and that was stock.
Beside the small gas tank,I think our Savage needs a 6th gear,or make 5th a little higher.
I guess thats the kid in me,faster faster ,I could never get enough speed,to this day I still lust for a 1100 ninja,but I know I would kill myself on it,actualy off it ,not on it,you know what I mean.

Ah, I think you;re remembering the Long Beach Freeway which serves the docks.  Big rigs three across all times of the day, pavement broken into jagged slabs by the pounding weight of overloaded trailers.  90% of the drivers illegal aliens -- talking non-human extraterrestials, not merely Mexicans; they think they are someplace where the laws of physics don't apply.  I don't use it.  To get to downtown LongBeach, the Aquarium of the Pacific, Parker's Lighthouse, etc. I take the Harbor freeway south then east accross terminal island -- much less traffic and joins up right at the southern terminus of the the LongBeach Fwy.

The Harbor Freeway terminates onto Gaffey in San Pedro, mainly carries commuters, especially south of the 405, so off hours it flys.  Which is amusing when you realize the CHPs base just off the Torrance exit.

Downhill and with a tailwind, I guess that could be done.

You've adjusted gearing, but most people have to remember that ALL factory speedometers over-read by a few percent, rarely less than 5% and usually by 8-10%.  

So, when most riders see around 90 on the speedo with standard gearing/tires as top speed for their Savage, they're probably doing 82-4.  Call it 83mph.

So what do you need to get to 100mph?  Wind resistance/tractive force is proportional to the square of velicty, and power is tractive force times velocity, so power is proportional to the cube of speed.

So, to rise from 83mph to 100mph you're trying to go 20% faster.   If 32hp gets your Savage to 83mph, to get to 100mph you need 32 x 1.2 x 1.2 x 1.2 = 55hp.  A 70% increase in power.

Sorry guys, there's just no way on this earth that a standard Savage is going to hit 100mph whatever the gearing.  Unless, maybe, you find a 50mph tailwind, a 1 in 3 hill, or ride off a cliff.

As Scotty said, "Ye canna change the laws of physics, Cap'n"

Been thinking about how to get to the ton on my '02. So far I've seen 94 mph twice tucked behind a laid down small wind shield. Took about 2 miles to get there on a loooong flat four laner. I'm wondering if the tweek on the ignition module will give me the needed extra rpm to reach the ton. Thinking about bending up a new right side piece of sheet metal to use as a air scoop to force more air into the air box, already have the air box door removed. The faster you go the more air will be forced into the air box. Need to grab ahold of the bike with a wish and a prayer and just let it run.  :). In stock trim the bike won't get there but I'll bet with some common sense tweeking it will.

Sort of Half English, Mum was a War Bride, British Army.  And, yes, I do drink tea, black tea, with sugar and milk.  But I'm lazy and use those new fangled "tea bag" things.

However "English" is a rather large group, the Island having been invaded a few times.  My ancestors were in the last sucessful group, the Normans in 1066.  I'm Norman English rather than Saxon English.  The Saxons had displaced the Celts who moved to Scotland and Wales.

While the Normans came over from Normandy, what is now France, they were not French.  They were Vikings that had settled in the north of France.  The Vikings pretty near went whereever they wished.  Except Scotland.

Somewhere in the past a Scot joined the family, Clan Cameron.  So I am also part Celtic.  Growning up I was told that my slightly darker complexion was from a Spanish great-great; but sis says mum now denies any such.

Mum, on her 80th birthday:
http://www.andruschak.net/Mums80th/Im002252T.jpg (http://www.andruschak.net/Mums80th/Im002252.jpg)

It's a lot easier on my father's side, straight Ukrainian, Zaporozhian Cossack.

When you do "the Ton", are you talking English or American?  The English use what we refer to as a long ton, 2240 pounds.  Except I would guess that they're now using a tonne since they've gone metric, which is roughly 2205 pounds.

Assuming that by "the Ton" we're talking the long ton since that is where the phrase originated, we have:

The Ton, English ---- 100 mph
The Ton, Metric -----  98.5 mph
The Ton, American -- 89.3 mph

If we really do go metric  the ton should be 100 Kph, or about 62 mph -- as in when going really really fast you are "going like sixty."

yeah I did 150km/h once just for sh *ts and giggles. Thats with a stage one dyno jetkit, 146 main needle (dyno needle) and a tapered exhaust. She is happiest at 110km/h though, as am I.

I was wondering about this one... has anyone ever told you that you have a slight accent?[

Yeah, but it's not from that.  Your accent is formed in your youth and is fairly fixed by age 15.  Years 1-11 were spent in Detroit.  Years 12 & 13, while my accent was still being formed, I lived at 18 Oak Road, Slade Green, near Erith, Kent, England.  When I arrived in the summer of '58 my Uncle Jack picked me up from the airport in his motorcycle-sidecar rig, a big two passenger sidecar.

  I asked once,no one said,How fast will a s40 go in 4th gear?

My red light came on at 78mph @5500rpm in 4th.

Redline (6500rpm) in 4th is about 94mph...I think we run out of power before we run out of gearing...
max in 5th would be about 100mph,..if we could get there...

What did the factory speedo indicate at the same time?[/quote]
The fact speedo indicated 98-99 mph with the stock tire.
At 60 on the sigma, it indicated 62-63. Now with the 140/90 rear it (fact speedo) indicates 59.

We all have thrown out different ways to get to the ton mark, mainly with engine mods and the chain conversion. How about aerodynamic changes, something to reduce our main enemy, air drag. My question to everybody is do you think there is less drag with saddle bags?. It's counter intutive but a set of bags cover up the sides of the rear tire and fender where I think there would be a lot of turbulance. I would think that they would also help smooth out the airflow coming off the rider's legs. Any thoughts on this or am I just tripping  :D

Aerodynamic efficiency certainly is one of the areas that has to be looked at coax a Savage to 100 mph. The classic teardrop shape generally offers the lowest drag coefficient.  I would hazard a guess that properly designed saddlebags that tapered smoothly to the rear within the teardrop envelope would reduce the drag and turbulence.  Iif the bags extended outside the envelope they would likely add to the drag forces. You'd probably get more benefit from adopting more of a cafe racer style with aerodynamic fairings

Now if you put a jet pack in your saddlebags...then we may have a winner...  :-)

My Baron's Tach shows 6,500rpm at 93mph in 5th gear. So does the tach run fast, or the speedo slow? At 60mph, the tach shows 4,200rpm in 5th gear.

Motorcycle Cruiser magazine..."RPM at 60 mph, top gear: 3940"...
translates to 99mph redline...
close enough...
your tach a little off.

How much difference does the Dunlop vs. stock make? Someone pointed out that the rear wheel is narrow enough to pinch the tire & make it even taller. If its supposed to redline at 99 mph with the stock tire on & someone gets to redline with the Dunlop on, then seems like they would just did the whole ton +a little.. Where are the gurus on this?

Post by serowbot on 11/20/08 at 09:06:21

The 140/90 Dunlop raises the gear ratio enough to make the speedo accurate...probably 3 or 4% when new...I figured it out once, but have since forgot.  Of course that changes with wear...
So, if you managed the ton, on a new Dunlop, it would really be the ton.  On the stock IRC's you better hit 108mph just to be sure.
