Every time that chain slapped up and down I kept pushing my phone away and ducking waiting for it to break and destroy. I caught myself 3rd or 4th time and was like its a video dummy.
Probably not that many folks here have run bikes on the dyno but when the ass end starts sliding like this one is around 3:26 that’s a real good sign it’s got a ton of power. I’d guess the numbers they came up with are on the low side of what this bike is actually putting down.
It's a bloody beast, that's for sure. Would not want to be on it when the chain craps out though, might need to take up some of the slack, for piece of mind, if nothing else...
How many miles do you think that engine will last if you used it as a daily driver with occasional strip use??? Oh yeah, that chain needs a little tightening, it's got way too much whip. Sounds fantastic.
It has a factory "style" primary and still can handle the horsepower it puts out. I wonder what primary setup he is using I know it sure as hell not a stock chain lol
Thats what Im taliking about??? Few know, the power of this bike, my bike is only 120" and 144 FTLBS and it is wonderful power, can only imagine what this bike feels like hang on.
Looks like that run was before the tune. I’d like to see it after it’s tuned to eliminate the big dip. And I’d love to know what the build consisted of.
TOTAL TEASE AND A MAJOR LET-DOWN = WHAT THE FCK IS THE POINT OF DOING A VIDEO, WITHOUT SOMEONE TAKING A COUPLE MIN'S TO SHARE, DETAILS OF ALL THE AMAZING, TOP-SHELF, HIGH- PERFORMANCE AFTERMARKET PARTS THAT THE BUILDERS OF THIS QUALITY MACHINE USED TO CREATE SUCH A BADASS BEAST
In all fairness the title says n/a does not specify fuel specs a 143 with the right head work and cam piston etc 200 is not a stretch of the imagination at all but probably not realistic on the street probably running some good compression. The dip looks to be cam pipe combo in that range more than likely a bike to run at hogs gone wild/ drag v twin. Nice job. lots of money
Awesome what a beast. You need to fab a chain tensioner on that so you don't gouge that nice swingarm Eventually it'll wear that rubber or Polyurethane block on the front of swingarm that guides the chain. Ps would love to have 😜
@@chuckleibengood5440 not really sad. That's the only reason it makes any real power. Even Harleys 131 stage IV feels neutered after riding the power cruisers I came up on.
Remember. Tight chin plus torque equals even more tension. This bike makes a FUKTON of torque. If it was as tight as it "should be" the chance of snapping it goes up significantly.
It’s just the slack on the return side where there is less pull. If you run a chain too tight on one of these you’re just asking to walk a bearing in your primary or transmission. The output bearing on a 6 speed is pretty weak to begin with so you want to be right around 1 1/4 inch in your chain slack.
Please help me to understand why. The strongest transmission that I know of would be the Baker Grudgebox, which is only rated for about 165. So with that much power, aren't you going to just keep destroying transmissions? Not to mention a HD cruise drive! The chain is only as strong as the weakest link. Will someone please clarify?
Pull the tire back a hair test with chain gaige, seems A little to much chain slop. Could just be the way it apears. Gauge will say. forsure. Might get better 1\2\3changes, quicker anyway. Doesn't have to wait for the slop to play out.
Is there a reason for the chain being a little loose?I'm thinking for the torque purposes maybe the slack prevents or helps with the chain not breaking under load
All that knowledge but for god sake the chain slap is ridiculous! Tighten it already. I'd like to see the actual dyno sheet cant believe everything u read
If you want to see it brake tightening it up. It won't last. Did you notice how it tightened up under load. Imagine if it started out to tight. Chains need play.
Sure would like to know how you got 210 HP out of a 143. If I had to guess, I'm saying a serious bump in compression, running E85 or MR12, and a really, really, aggressive set of cams with total valve lift around .720 to .750"....am I right?
The s&s t143 puts out 160hp the star racing 160 is a pro stock custom engine. These are not built normally aspirated harley engines. Hell i can take a stock harley engine and nitrous inject it to get big numbers so what? Of course it will fly apart also.
Chain drive also see the belt craze is past after all that's what washing machines have and motorcycles had before they invented the chain far stronger and ain't gonna slip either!
Not with the numbers this man is putting on the dyno he will eat a fxr in the straight line, if you think your gonna get him in the corners, your wrong also he has a raised rear suspension and raised inverted forks from olin let alone Brembo brakes front and rear his lean angle is better than a fxr. that bike would kill a fxr anywhere.
But it seems to allow the motor to breath more at the top end, and the amount of power available at lower revs is more than adequate - indeed it'll make the bike more tractable in town and traffic..... I would say that the bike would be good fun to ride with plenty of torque for everyday riding and lots of brute force above 3500rpm.... plus those open pipes sounds GREAT !!!!!!
It's nitrous, not n/a that's why. As if they've got the secret recipe to 200+ whp n/a no one else has. There's way too many Harley shops out there for this to be the only one to make it magically happen.
@@RidinDirtyRollinBurnouts Then where is the bottle that is the tank for the nitrous ? The graphs show that the pipe is not providing enough back pressure centering around 3500rpm, when the engine gets up around where the torque starts to taper off - this is normal for S&S 143's. The BHP also suffers at 3500 but it is higher at 4 to 5000rpm - again normal for this engine. and such a big engine is never going to breath correctly at lower RPM if the heads are set up (with bigger valves) for top end power. This is showing that the pipes are just too small for the size of the engine - and that is why S&S markets their own pipe just for the 143 which avoids the (probably reversion) problem . Remember this engine was built for baggers and bagger riders don't rev their bikes that high...... S&S know more than most shops and certainly more than you do !
@@OneSikScraper thank you so much I've been using those but it so much controversy about using anything but harley plugs. I noticed my bike runs better with these.
Any one can make power out of a big engine we used to make 1oo hp out of 80inch years ago so not that im pressive when you factor in the cost make it lighter and tune it better way to go just my opioin iy,s callled eficincymake the most of air and fuil in and out just my opion. cheers.
Yeah? And? It's people's passion that build these bikes. It's like buying a classic dodge charger, sure, a brand new vette would be a better investment, but other people sure as hell will love the charger more.
I can build this way under 50k That T143 motor is about 9k before aftermarket work, grab a RG with a blown motor, slap that in, up the compression a bit, run good fuel, I could set this up around 25-30 (unless there's expensive shit here that I don't recognize)
@Ben Franklin If you look at 3:05 with the bike all assembled they are blurring something out by the gauges and the power is not linear it jumps fast at around 3500 so I would question this.
With such a large flatspot between 2.5k rpm and 4.5k rpm I would suggest there is something wrong with this bike - maybe that exhaust needs more volume or something.......
The torque to HP ratio seems low AF to me,on a super expensive build like that the torque should be damn close to HP,atleast that's how its worked out for my 2003 88 ci Road King 103 CI stroker ,and on my 2012 103 ci Fatboy 110 Stroker ,both bikes were easily tuned where HP and Torque are within 3 points of HP ,an over 50 - in torque seems awfully strange seeing how my brothers Street Glide is making just under 200 ft lbs of torque ,as pointed out by dozens of others that chain slap could be easily cured with a tensioner,I run a tensioner on my Buell Lightning and it slowed down chain stretch pretty well .
LMAO! 143ci V-Twin engine. You better pull those numbers! Let's see if it can drive from the NJ shores to CA and back without problems. It's very cool but you should call it what it is... a 143 race engine! This is not a daily driver engine.
Bro builds a badass bike but……. That chain slap is about to fuck your shit up if you keep ripping it like that especially standing next to it like that……
That bike is supposed to be some big deal? It doesn’t even have passenger pegs or Legend suspension. I had an 04 nigh train with a stage 4 95” kit, and it would outrun that thing. 😐
We're talking about a t143 SS not a fuel moto m8 143. Based on your name I'll assume you'll get me saying a lsx 454 hits xxx HP so a vortec does the same. Different animals and you can hear the spray hit.
@@Effininja Hammer performance has made 150rwhp with a 90" sportster based engine... U really think they can't get over 200hp from a 143"??... educate yourself. The stock engine makes over 160. Off the shelf. Its a 2.4 liter motor. U can gain more simply off a fuel and timing change let alone porting and cams. And for the record I actually own a scratch built turbo vrod making 162rwhp on bone stock engine and injectors on 9psi from a t3 turbo off a saab 900, been in the bike and still running strong 13 years later and I built the entire system and thats a 69 cubic inch engine with low boost. As for the 454 reference I also own supercharged 496bbc in a 454ss now making over 1k hp on 12 psi from a v-27 vortech ysi-B billet wheel blower. Afr heads chris Straub custom roller cam hooker supercomps and csu blow thru carb. And an 88 fxr built 96" s&s ported heads woods cam putting down 114 hp 116 torque on 91 octane. Read a book build something and educate yourself.
Pfffft ......guess you forgot to look a sheet thats means absolutely nothing ....nowadays done all the time and more. 175-180hp 140inch with street manors. You might be a bit behind the times....
Doc Holiday then lets see the dyno sheets. I have seen the new 131 run and it was 127hp. I made 105 in the early 80s with lots of time and money in my shovel. It would snap a chain and you couldn’t put it to the ground it would just fry tires. I can see over 150 on race or more blown but lets see it.
Ron Jacobsen wouldnt matter....your out of the loop. Yep still running a 95 hp shovel myself ...but snap the chain? Really....better go figure chassis shit out.... But a 140 evo i have is easy 170 hp with less than 11 to 1. Go do some research my friend.......there is a 326 hp bagger running around NC street ridden bike.... my silly ass junk M8 bagger is already at 127hp nothing special ..bolt on shit ridden everyday here in new england from 28 F to 100F . You do realize there are 155-160 inch motors out there doing 200 all day . Hey have a nice day.....go do a little research 😂🤣😂🤣
S&S has a full race 143 and its only 160 rewhip and not on pump gas i was told so i would like to see 200 from this 143 cu engine. And theres is not street able. I ride a 13 anv ultra limited so hp is non issue compared to my zx14 last bike or turb busa before that.
A stock se 117 only puts out about 94 hp. What bolt on kit are you referring to? A stage 4 new jugs heads injection and tune is hardly bolt on for most of these guys and your still a long way from 200 maybe 120 ish. 300 riding around and a harley? What a nitro burner? My turbo busa wasn’t pulling 3 about 280 and it wasn’t a street ride any longer even if it was legal. You cant go down the interstate lofting the front end every time you shift just doesn’t work too well.also a shovel isn’t a evo as you should know its a farm tractor with all the power down low . Harnessing it can be a problem with high hp. Chain snap. No traction burned up starters. Ectttt.
@@sebastianochs7714 well ya do to get there. It was a cut in where he was already in high gear. As far as knowledge goes. It depends on what ya want to know during other gears. Glad you are looking to be smart.
Not trying to be a dick but I’m not seeing 200plus on gas normal aspiration harley engine pulling 200. I could be wrong but you would need 180 cu at least. Iv run fast harley and over 100 hp to me is great. But unfortunately harley has lost me and many other customers.
@@billgonzales8978 Not a drag bike but it will break 200mph. It's plenty fast from a standing start. Street legal and most important totally dependable. Don't have to worry about it flying apart.
Its a s&s purposely built large displacement engine. Ot a built up stock harley engine. I can put a Pratt Witney f100 engine in a frame and get 1000s of horsepower so what? Lets see a built stock harley engine on 93 no blower turbo or nitrous pull 200 plus.
@Jesse Mitchell I believe u are thinking of the "S1000 RR" not an "S1000R" as he wrote. Which is designed for all the things u mentioned, look it up. They are one of the top choices for riding vacations all over Europe, due to their comfort, power, handling, braking, riding position, equipment, luggage etc. etc. :)
@Jesse Mitchell A couple of their models have had reliability issues (although no worse than a couple of manufacturers I could mention) but in general, for decades reliability and rugged construction has made them the weapon of choice for globe trotters since I began riding in the late 60's
