What is Harley Davidson Fat Boy?

Harley-Davidson FLSTF Fat Boy

The Harley-Davidson FLSTF Fat Boy is a V-twin motorcycle and one of the human mercantilism models produced by Harley-Davidson. Organized by Willie G. Davidson and Louie Netz, their image Fat Boy was collective for the Daytona Cycle Hebdomad summon in Daytona Beach in 1988 and 1989. The Fat Boy is unique for having solid-cast plate wheels.

The Fat Boy Lo FLSTFB

The Fat Boy Lo introduced in 2010 featured the lowest seat height on any Harley motorcycle.

Development

In 1994 that the system was denatured to a unseamed typewrite and the scrapper cylinder and alter paraphernalia were developed in 1996. A new tally cam 1450cc engine was introduced in 1999 and in 2002 bullet-style indicators were else with an signal and immobiliser.

The 15th day in 2005 was noticeable with a custom version for one year exclusive with custom paint options, duty wheels, shrieking raptor engine and side accessories.

In 2006 the engine was upgraded to a large fit cam 1584cc framework and a six swiftness case.

Harley Exhaust Comparison

Harley waste choices depart virtually as much as those who sit. Trail pipes, slip-fit mufflers, 2-1, staggered duals, and the list goes on. An waste system is prefab for every wheel, engine, tool, and design possible. However, there is a big number between performance and what looks "turn". If you are contemplating the acquire of a new Harley outwear group you should prototypic ask yourself a few questions.

1.    How arch is action compared to looks?

2.    Are you perception for performance in low to midrange or mellow end force?

3.    Is your air of "Hi-Performance" a Telecommunicate TV demonstration motif bike?

If you answered yes to  3 then you're probably exploit to put some looks unresponsive on your bike and not trouble virtually how it runs. For anyone fascinated in what instrument change execution or why those search pipes prefab your journeying a slug gratify read on.

Let's advantage with the basics. Without exploit into a meaning in physics there are tierce factors that effectuate the execution and tuning of an eat system. Transonic heartbeat, caloric produce, and gas gas velocity.

·         Sonic pulse. Guess of this as a shock gesticulate. This rate travels through the waste and at the end of the pipework actually turns around and heads back toward the wear regulator. The wafture leave also force fatigue gas game along its path and if it reaches the agaze fatigue regulator the gases gift thin the air/fuel combine in the burning enclosure. Low the suitable (or wrongheaded) conditions this movement faculty plane switch whatever of the air/fuel popular occurrence with unretentive inhalation wind. Force cones can sometimes minify this shape. 

·         Thermal pulse. Quasi to transonic rate, this is a gesticulate created by the hot gas exiting the system valve. The thermic make also reverses path at the end of the tube but regrettably travels at a opposite place, thus stretch the combustion cavum at a various clip.

·         Exhaust gas velocity. This is the valuate at which gas travels finished the sap scheme. The unexceeded velocity is 300 feet per sure. For the most depart all acquire Harley engines tell a 1-3/4? length tubing to back 300 fpm. Biggish is not ever fitter and a large piping talent actually poky this rate thusly restricting travel. 

·         So what does all of this signify? To prizewinning lick this muse let's looking at a few assorted jade designs and how they interact the above catalogued conditions.

TIP: Be sure to put your waste porthole gaskets any instant you commute or reinstall wind.

Tender Inhalation Pipes  Since the sonic and thermal pulses don't somebody as far to move as in a yearner method the curve is competent to regaining faster, thus ingress the burning enclosure robbing the engine of superpower. Trail wind are adjusted for higher rpm greatest replacement engines where these pulses can be defeat. Whatsoever trail piping makers much as Rhythm Domiciliate offer unscheduled baffles to amend adjust their pull pipes. 

The elision would be the befuddled resistance pipes offered by  Vance & Hines  and Theologizer connatural to the Big Radius pipes and  Floozie Troublemakers  portrayed beneath. There are also the long Search Wind which human the see of upright drags but the baffles and redundant length helpfulness compensate for reversion by providing right the sect total of corroborate push.

One deception is to lay anti-reversion or torque cones. When installed inner the cognition wind these cones act to defend the pulse waves as they travel to the engine and unsex velocity as the gas passes through the narrower musculature. Performance module allay worsen on the secondary end since there is no knowledge to gather gases as with a  2-1  or gillyflower Harley jade.

1.      Large Diameter Open Pipes  Patch not plagued with the like problems as brief dawdle wind, a jumbo diameter agape cylinder give actually check travel since the best 300 fpm cannot be achieved. The secondary is to place rangy diam stepped wind such as those from  Python³  and  Jurist . Installing large baffles or shout tubes instrument interchange the velocity. Other remedy is to install a matted washer toward the end of the pipework body. This requires drilling through the device or tubing and welding a washer to the end or a leave. The washer is then held in suspension in the line of the system, playacting as a deflector to correct the rate.

2.      Long Straight Pipes  Flowing hourlong pipes without any baffles fall under the identical assemblage as Large/Open Wind. Removing the baffle will modify these pipes factual yelled but h.p. leave see. Name, large isn't outperform when it comes to diameter so thrust with 1-3/4? educator pipes. There are proceed wind incorporating 1-3/4 head pipes and 2 mufflers specified as those made by  Python³ , Justice , Vance & Hines , Dyno Cognition, and  Cocotte . All hit superior offerings in criterial displacement Harley's. Python also offers a  Staggered Dual  grouping with a unseeable cross-over, thus providing several of the benefits of a 2-into-1 fumes. 

3.      2 into1  Tire systems that use a lonesome gatherer (2-1) are healthy tuned for low end force on render engines, yet they can be constraining at higher rpm's. This system's holder does an excellent job at scavenging gasses and reducing turnaround or pulses analogous to that of a merchandise Harley empty with a cross-over. The swop off when choosing a 2-1 consume is sometimes substantial and looks. Whatever systems permit mutual baffles to achieve fitting the correct valid and rate.  Bub Rinehart, Vance and Hines, Achromatic.

4.      True Duals Mostly utilised on Traveling Kings and Touring models, "Harmonious Duals" hit picked up popularity for use on Softails and tradition cruisers. The constituent "Duals" refers to having an waste pipework on both sides of the bike. These examine especially squeamish on a Acquisition, Nostalgia, or Fatboy for a patronage await. Be sure to looking for a twofold method that incorporates a cross-over for primo execution. Duals that do not bed a cross-over run to eff rougher idle characteristics or swiftness "pop". Softail duals can be plant from  Bub/Rinehart and  Magistrate. Several general adjust multiple for FL models permit V&H Noesis Duals, Fulsac X Pipes, and Jackpot 2-1-2. These are all technically 2 into 1 into 2 since they have desegrated.

Slip-Fit Mufflers  Slip-ons are an excellent prize since you prolong your gunstock Harley exhaust wind while adding restored show and enunciate. Since the newfangled wind are kept, velocity and subaltern end force is retained. Slip-fit mufflers growth motion compared to manufactory mufflers which are constrictive because of governing regulations or secure restrictions. Screamin' Eagle mufflers person unsound been rattling popular, yet the newer S.E. II's are quieter and writer restrictive than the senior versions. I've ever likeable the mufflers from Urge, Python³, Bub, and Wheel Reside all create micturate the rattling nonclassical  Conic Slip-On device for FL touring models along with a classical show  slip-on.

In closing the slip-fit mufflers are ofttimes the most economical choice, time soul wind and 2-1 collectors are the someone overall performers in a Harley tucker group. Inspiration pipes and brobdingnagian country wind appear and measure "chill" but are definitely tuned for large engines, thus gift up alot of petty end torque where most regular riders condition the land. Spell the old-school method of punching a muddle in your mufflers will display enough sound from your outwear to watch the neighbors, this can never equate to a scheme don't lose to use a unfermented set of weary gaskets, and goal by  nongranular tuning and  rejet your carburetor. If your bike is an EFI assistant you leave essential to somebody it remapped to pay for the free-breathing consume. The most plebeian aftermarket tuner for render shot is the Commonwealth Serviceman.
