====== Overview ======

From 1986-1987, the stock Sportster carburetor was a Keihin 34mm, fixed-venturi "butterfly" model, as used on the Ironhead models from 1979 onward (BT models still used the 38mm version). Contrary to popular folklore, all Keihin non-CV carbs did come with accelerator pumps.

In 1988, the stock Sportster carburetor was upgraded to a Keihin 40mm, slide-type, constant-velocity model. It was quickly discovered that the lack of an accelerator pump was a shortcoming. To help that situation, a special needle, identified as 27094-88 or N65C, was used to help off-idle performance in the 1988 models.

In 1989 and thru 2006, the Keihin CV40 carburetors were produced with an accelerator pump to smooth out initial throttle response.

====== Keihin Butterfly (non-CV) Carburetor (Stock on 1976L-1987) ======
  * The Keihin non-CV carburetor is a horizontal type with a fuel bowl, single ring-shaped float, an accelerating pump, idle mixture adjusting needle and a throttle stop screw for speed adjustment. ((1970-1978 HD XL/XLH/XLCH/XLT 1000 FSM))
  * The throttle body casting contains an integral venturi and a fuel valve seat that is pressed into the body. The underside of the throttle body contains a boss. The main jet screws into the boss and holds the bleed tube in place.((1970-1978 HD XL/XLH/XLCH/XLT 1000 FSM)) 
    * **Operation**: Fuel from the gas tank passes through the fuel valve, onto float chamber. The fuel entering causes the float to rise until it shuts off the fuel valve, stopping the flow at a level predetermined by float level setting.  ((1970-1978 HD XL/XLH/XLCH/XLT 1000 FSM))
    * **Idle or Slow System**: The slow system functions at idle, low and intermediate speeds when throttle valve is closed or only partially open. At idle, fuel enters the main jet and, after being metered there, enters the slow jet where it is metered again. Fuel from the slow jet enters the slow jet bleed tube where it mixes with air through the slow air passage. Fuel mixture is regulated by adjusting the idle (low speed) mixture screw. When the throttle valve is closed, fuel mixture flows into the venturi almost entirely through the idle port. As the throttle valve gradually opens, fuel mix discharge is transferred to the bypass. The slow jet bleed tube is actually a part of the slow jet. ((1970-1978 HD XL/XLH/XLCH/XLT 1000 FSM))
    * **The Main System**: The main system functions at intermediate and high speeds as the throttle valve opens further. Fuel is metered by the main jet and enters the main jet air passage. The fuel/ air mixture then exits from the main nozzle and into the venturi. ((1970-1978 HD XL/XLH/XLCH/XLT 1000 FSM))
    * **The Accelerating Pump System**: The accelerating pump system works with sudden throttle openings (rapid acceleration) to quickly inject fuel into the carb to provide extra fuel for the engine demand. Rapid throttle action pushes the pump rod down, flexing the diaphragm, which compresses fuel underneath the diaphragm, forcing it up past the check valve and out the pump nozzle into the venturi. The check valve prevents backflow while the pump nozzle meters the flow. Spring action then returns the diaphragm back to it's original position. As the diaphragm returns, a new supply of fuel flows in and under it so the system will be ready to repeat the cycle with the next rapid throttle action detected. ((1970-1978 HD XL/XLH/XLCH/XLT 1000 FSM)) 
    * **The Choke System**: The choke is manually set by pulling out on the choke button. Pulled all the way out is fully closed (for cold engine), partially open (for warm engine) or pushed all the way in, fully open (for warm engine). ((1970-1978 HD XL/XLH/XLCH/XLT 1000 FSM))

====== Keihin CV 40mm Carb (1988-2006) ======
  * Constant velocity, gravity fed - has a float-operated inlet valve and a vacuum-operated variable venturi (movable slide).
  * Both the CV40 and CVK carbs are made by Keihin in Japan. But only the CV is specific to a Harley and has the bar and shield and HD name on the side. ((CVPerformance of the XLFORUM http://xlforum.net/forums/showthread.php?t=1729649&page=2)) \\ CVK is for Kawasaki and various other makes that contracted Keihin for that carburetor. \\ There is also a CV40 making the rounds that is distributed by a Florida company that looks identical but not all the specs match up. \\ There is no guarantee that any part (original or CVP) will fit those knock-off carburetors. \\ If your CV carb does not have the name Harley Davidson cast above the bowl on each side it is a knock-off. 

^Torque Specs ^^^
|1988-2001  |Intake Manifold Flange to Cylinder Head Bolts/Nuts  |72-120 in/lbs (8-14 Nm) |
|2002-Later  |Intake Manifold Flange to Cylinder Head Bolts/Nuts  |96-144 in/lbs (10.9-16.3 Nm) |

== Operation: ==
  *  The carburetor atomizes gas in proper proportions to the air  pulled in through the air intake. At idle, a small amount of gas is siphoned through the pilot jet by the incoming air. The more the throttle is opened, the air begins siphoning through the main and needle jets. The tapered needle increases the flow of the needle jet as it is lifted since it's taper gets smaller as it sets inside the needle jet thus allowing for more flow when lifted up and out. Vacuum from carbs intake,the engine side of the throttle plate, is used to lift the slide barrel/ needle jet. At full throttle, the carburetor venturi is fully opened and the needle is lifted far enough to allow the main jet to flow at full jet capacity. The choke circuit is actually the starting enrichment valve system. The choke knob opens an enrichment valve. With the choke knob in the open position, the slow jet sends a stream of gas into the carburetor's venture thus enriching the gas/air mixture when the engine is cold. The accelerator pump circuit injects a fine spray of gas into the carburetor intake during sudden acceleration to reduce engine hesitation.

===== Factory Keihin CV40 Carburetors by Sportster Model/Year =====
===== Emissions Observations ===== 
by Almond farmer: ((http://xlforum.net/forums/showthread.php?postid=5567479#post5567479))


  * There were no HC emissions changes from 1981-2003 @ 2.5 g/km .
    * 78-79 is 14 g/km
    * 80-81 is 5 g/km
  * Any carburetor can meet those standards
  * In 2004 CARB went to 1.4 g/km and EPA (49 states)in 2006, last year for XL carburetor.
  * CA is the only state in the country with its own emissions standards which are currently the same as the EPA standards.
  * In 2008 CARB mandated only .8 k/km HC and EPA with the same requirement, followed two years later in 2010.

<blockquote>The above #s are combined HC + NOX</blockquote>

  * Noticed the Keihin 40mms CV used 160 main jet for the 883 up to 2003, then 2004-2006 went to 175 (1.75mm) for 49 state bikes, not CA bikes.
  * This change makes the air/fuel mixture run richer, therefore, a richer mixture results in lower combustion temperature with resulting lower HC +NOX to meet more stringent emission standards.
  * Notice the 49 state 1200 used 170 jet up to 2004, 180 main jet (MJ) in 2004, & 185 MJ in 2005-2006.
  * CA 883 went from 170 MJ to 2003 then changed to 180 MJ in 2005-2006.
  * Again making the air/fuel ratio richer.
  * CA 1200 cc went from 160 MJ in 1989 to 185 MJ in 2006. So, the 2006, 1200 evo with Keihin 40mms CV with vertical needle used the same main jet (1.85mm)for all 50 states, since CARB & EPA had the same emission requirements on the MoCo in that time.
  * Note that jets are selected for operation at below 4000 ft elevation.
  * If installing CV to 1000cc IH would first select 170 main jet below 4000 ft elevation. This Keihin CV should return lower emissions than any of the Keihin Butterfly carburetors and even satisfied the tier 1 CARB emissions requirements.
  * Unfortunately, CV could satisfy tier 2 emissions at only .8 g/km.

====== Enrichment Cable ======
===== Sub Documents =====

  * [[techtalk:evo:carb01f|Repairing a Broken Enrichener Knob]] \\
\\

The CV40 has an Enrichener Circuit - The knob is labeled 'Choke' but that is a misnomer. It is NOT a choke. \\
A choke sends less air into the venture when closed thus richening the mix. \\
An enrichener shoots gas into the venture thus richening the mix. \\
It may seen more semantic to call them different names but it is important to realize that the two have different functions to the same end. \\
(to richen the mix for better starting). \\

{{:techtalk:evo:carb:enrichener_cable_1_by_hippysmack.jpg?direct&300|}} ((photo by Hippysmack)) \\

The enrichener knob should stay open and remain open when pulled out and close without binding when pushed in. \\
Pulled out engages the enrichment circuit and adds extra fuel into the venture. \\
Pushed in closes off the enrichment circuit stopping extra fuel from entering. Read more about it's function [[techtalk:evo:carb02#enrichener_function_choke|here]]. \\
To adjust the knob, gently pull it out to the full length and let go. Do not pull hard or at an angle or it could break the knob. \\
Tension from the plastic nut behind the knob keeps it from pulling back in. If it tries to pull back in on it's own, the plastic nut isn't tight enough. \\
You can tighten it with one hand by hold the knob all the way out with your finger and using you thumb and next finger to tighten. \\
There is no need to take it off the bracket for this. You just want to create enough resistance to keep the knob from pulling in on it's own. \\
**Caution**, the plastic nut fits onto plastic threads and should not be tightened too much or the threads will strip. \\

====== Discrepancies in the FSM(s) / Parts Catalog(s) ======
Upon perusing 1986-2006 Parts Catalogs for carburetor information, it's clear that the MoCo was trying to save space in these books at the expense of legibility. Below is a chart showing the initial intentions on the top and the MoCo's mis-interpretations on the bottom. They give no notations (from year to year book) on any changes to the nomenclature. I.E. one way to display a year/ model number is displayed differently in other year books. This chart is not complete nor factual in numbering but as an example only. 
For instance:
|Parts Book|Description|For Model(s)|Part fits model(s)|Notes|
|86-90|00000-86|88 - * XL1200|(88-90) XL1200|Easy to understand, * means \\ to the last date the book covers|
|86-90|00000-86 (86-87 883)|90-XL1200|(86-87) XL883 & (90) XL1200|Little harder \\ (more to think about)|
|86-90|00000-86|86-* all models|(86-90) XL883 all & (88-90) XL1200|Easy to understand, blankets all models 1200 \\ first made in 1988 but it leads you to believe \\ they were made from '86|
|86-90|00000-86\\ 00000-86 (Cal)|89-* XL1200 \\ 88-* XL1200|(89-90) XL1200 - (49 state)except California \\ (88-90) XL1200 - California only|No suffix after desc. means domestic models \\ (Cal) after suffix is California models only|
|91-92|00000-86 \\ (91-Cal)|91-* XL1200|(91-92) Xl1200 (domestic) \\ (91) Xl1200 (California)|Both Cal and Dom models|
|93-94|00000-87 (93-Cal)\\ 00000-86|93-* XL883\\ 93-* XL883|(93-94) Xl883 (California) only\\ (93-94) XL883 all models|Reads it but doesn't mean for Domestic\\ Domestic (49 state models)|
