S&S 144 engine Specs

[1FSTRK]

Because "my guy at S&S" is really just me reading here on HTT thought I would ask if there has been any new info on the heads for this motor.
Many have posted or PMed that they would be getting flow numbers, pictures of the ports and combustion chamber, CC's for the important parts and etc.
Just checking in to see if any progress has been made.

Im with you steve on this one - my 124 is stable - decent mileage depending on what map i have in it at that time - and this 124 could give a damn about being doubled up or not - still absolutely hauls ass . You can only get so much of it to the ground anyways , and thats what it comes down to. Im not at all worried about these 144ers - line up next to me - slip just a little bit and ill show you a tailight .

the rider does make a HELL of a difference 

but awfully hard to overcome a 40 hp advantage   

can be done though...but not on a regular basis

there's always somebody faster...

  Having the coin to buy a big power engine is not the same as having the skill set to use it.  Then there is also the limitation of the chassis.  Reminds me of the time I lined up against big muscle big block w/ my 95cuin.  I made it to Sauget and he made it upside down in the ditch.  So, the real way to tell is not by measuring wee wee's on the net or calling people out.  It is actually showing up and twisting throttle that gets it done for me.  I don't race dyno sheets no matter how inflated.  I race on wheels.

And any real racer knows on any given day he can be beat by himself or someone with less power but he also knows that is not the norm and so he will take all the power he can get. Funny how it is often the guys with less power that do all the bragging and claim it is never just sour grapes.
Ever wonder how many guys out there have a bar stool at home to sit on while using their computer?

What was the 1/4 mile time on that 143?  What about 60 ft times?  How did the 180 tire do?  What about 1/8 mile?  Or realistically.  You have no baseline to go on and you have no idea what it can or cannot do.

What I find hysterical is the tall boots that have been needed here on this forum lately.  I guess it's the start of winter.  The keyboard racers are out.

You may have mistakenly posted to the wrong thread. This thread is
"S&S 144 engine Specs"
Not sure what your posts have to do with it.

[hrdtail78]

The Specs of the 144/143 have been covered pages ago.

[1FSTRK]

I brought this thread to the top this morning with my follow up questions on the heads, after that the thing just tanked. No good reason to ruin a thread on a particular subject with all the off subject winter time trash talk. Start a thread on trash or street racing or drag racing and maybe others will come key board race with you but once you drag a thread down we never seem to get back to the answers to any legitimate questions. All the spec questions have not been answer, you have a shop, you tune, you race, if you want to post the answers to my real spec questions I am all ears. The other guy is new here but you are better than this.

Or have never went a round in their life . Much less seen the winners circle .
Got a race bike that is a show bike . Or got a show bike they claim is a race bike .
Couldn't cut a light or find the groove if they had too. But the run a pretty good suck.

I was just agreeing with doubletrouble there, and stating that the motorcycle with the most HP doesn't always win.  There is more to it than that.

This basically covers it.

But your right.  If I got in the way of you getting your info.  I apologize.

S&S oil pump set up no cams for it other than what S&S has to offer. You could remove all of it and buy new pump plate cam cover etc.. More power for what. You got guys out there that cannot figure out how to make 140 hp work with out burning out the clutch, tearing up drive train parts..

Then let the dyno games start  as not like it's a mystery some drums are reading higher than others,....or maybe race track results, who knows ,

But if I can pull a 7.30 in the 1/8 on a  bagger with a basic out the box S&S engine with approx  20 less hp and almost the reduction on tq .. I am betting that bike with a rider that can figure out you dont need max rpm to launch and not burn down parts will be a 10 second member or high 6 if its the 1/8 mile crowd.. 

high 9's  and low  6's .
smoking the clutch sucks ,but it happens. riding home with a squawking clutch is no fun.


anyone have flow sheets on the B3 Heads yet ? its been over a year now

  Jim...I know a guy that has a set of heads that flow 410 cfm's @ .700" lift that is just a phone call away.

  Would be impossible to give seat ID as finished, they are non concentric

The CNC program S&S runs on the heads runs all the way down the short turn and past the bottom 60 deg angle on the valve job

  They do no measure even close to the same at 12/6 or 9/3

  I don't know what they use to flow the heads....I use a delrin ring ring with a 1/2" radius

.4-288.7

.5-322

.6-343.9

.7-350.2

.8-359.8

I think most head porters already know this, but the TB or even the heads is not the problem here.  It's the intake manifold.  I have a set of B2 CNC heads that flow just as well as the B3 heads after a "buff and fluff" but with smaller intake and exhaust valves (2.2 and 1.7).  The heads flow very well and more than sufficient to feed the motor in question but if the intake manifold restricts things too much, that can be a bottleneck for sure.  I think we need to be careful of "bench racing" on a flow chart.  That hardly tells the whole story.  The whole story will be how the build runs with all the assembled parts as a combination.   Regards,  -Tutt

I agree that the launch is going to be the crucial deal and for a guy like that rides the bike and really does care if I am beating the clutch vs a bike that is going to used for a magazine deal and so what if they burn up a few parts are two completely different things. 

As for my clutch I have switched over from carbonite ( black)  to kelvar  ( red) .. Will see how that works. Its not burning the pack like I thought ,  Pack looks decent but its engaging smoothly at all..    Barnett has been great with this and sent me two new  complete packs ( steel and fiber)  to test.. 


Myself would love to buy a 143 and drop it into a road king , extend the swing arm and have it for a pro street style mainly drag bike.  TOO many irons in the fire at this point.. between shop , the truck, bike and then LIFE   

[RevFastEddy]

That's going to be about 670 lift on those stilts, isn't it?  They must feel very confident in their valve train for long term use.  -Tutt

Definition of long term:   The warranty is 6 months.... so long term would be 6 months plus 1 day..

[joe_lyons]

Maybe two days
