- | There are a lot of Sportsters out there that do not have their original Bendix carb attached to them. \\ | + | 76-78 Keihin carbs do not have an HD number on it or a stamp pad for numbering. The Keihin number is stamped in the flange. \\ |
- | Consequently, this page will try to bring to light at least some the differences in these carbs. \\ | + | The best way to identify a 79-up Harley Keihin carb is to read the Keihin number. \\ |
- | One could say it's a blessing that Bendix carbs for Harleys will interchange. \\ | + | It's the first 4 characters stamped on the (R) choke cable side just above the bowl. \\ |
- | One could also say it's a curse. \\ | + | The HD part number on some models is on a sticker placed on the top of the carb. \\ |
- | Bendix carbs for Sportsters were set up for Sportsters. \\ | + | Older carbs either weren't labeled or the sticker may either be missing or unreadable. \\ |
- | Bendix carbs for other HD models were set up for the needs of those motors. \\ | + | |
- | Changing the jetting alone (on other intended model carbs) to Sportster specs may still not give the results intended. \\ | + | |
- | The 27155-72A Sportster carb has another number stamped into the ID pad (13732). \\ | + | |
- | This Bendix part number denotes a certain configuration carb body and / or internal parts. \\ | + | |
- | **Change Letters**: \\ | + | |
- | You may have noticed a letter beside the HD part number or it may be arbitrarily stamped in the ID pad away from the HD number. \\ | + | |
- | Carbs with changes made during the build phase had the change letter included at the end of the HD stamped part number. \\ | + | |
- | Carbs with changes made at the dealership (customer owned bikes) had the change letter stamped into the existing ID pad...somewhere. \\ | + | |
- | This explains the arbitrary location of some of the change letters. \\ | + | |
- | For example, an "A" stamped into the ID pad away from the HD part# is a Bendix modification letter, not a suffix letter to the HD part#. \\ | + | |
- | **Bendix model 13479**: \\ | + | As for interchangeability between butterfly carbs; \\ |
+ | Any Harley Keihin butterfly carb will interchange but the ones for big twins will need to be re-jetted for a Sportster engine. \\ | ||
+ | The chart on the [[techtalk:ih:carb01#sportster_keihin_carburetors_by_year_model|Basic carb information page]] has the factory jetting information for Sportsters. \\ | ||
+ | You may have to go up or down from there depending on what's already in your carb and your specific engine/A/C/exhaust setup. \\ | ||
- | The model 13479 carb was used on FLP, FLH and FX model Harley Davidsons. \\ | + | Also, 76-78 Sportster carbs have a 38mm venture (measured at the smallest point near the throttle plate). \\ |
- | The letters A, B, C, D, E and F stamped near the basic Bendix part number (13479) are change letters. \\ | + | 79-87 Sportster carbs have a 34mm venture. However, the carbs installed on BT's may be 38mm. \\ |
- | Meaning they denote certain changes made per carb model. \\ | + | To find the venture size of the one you have, cut a piece of cereal / kleenex box cardboard 34mm wide and insert it into the most narrow part of the venturi. ((IronMick of the XLFORUM http://xlforum.net/forums/showthread.php?p=4457592&highlight=keihin+bowl#post4457592)) \\ |
+ | Tight fit = 34 mm, loose fit = 38 mm. \\ | ||
- | The following changes are noted in Technical Service Bulletin (614A). ((HD TSB 614A dated April 14, 1971)) \\ | + | See the pics below for a visual confirmation of year model features. \\ |
- | * **Change for 13479A**: | + | |
- | * The float setting was changed from 1/8" to 3/16" to remedy a rich condition occurring at steady speeds. | + | |
- | * The clearance between the float tang and the wire clip on the needle decreased. \\ It should be .005"-.010" between the top of the tang and bottom of the portion of spring that hangs over the tang. | + | |
- | * **Change for 13479B**: | + | |
- | * A new choke valve has detents with a spring loaded plunger engaging the detents to provide positive positioning throughout the choking range. | + | |
- | * New part (27664-71 choke shaft replaces 27664-70. | + | |
- | * New part 27665-71 plunger added. | + | |
- | * 27666-71 plunger spring added. | + | |
- | * **Change for 13479C & 13479D**: \\ Changes were made to correct over-rich mixtures in the intermediate (off idle) speed range. | + | |
- | * A new idle jet has two .06mm holes instead of one .08mm hole near the screw end. | + | |
- | * New part (27725-71) idle jet has the letter 'A' stamped on the screw end and replaces 27723-71. | + | |
- | * The idle air bleed hole in the carb body was enlarged from 3.35mm to 3.60mm (app. 9/64: in diameter). \\ Idle jet (27725-71 must be used with the drilled out passage in this carb for proper carburetion. \\ Dealers could drill the bleed hole and stamp the change letter //if// there was a problem with the field unit's performance. | + | |
- | * The accelerator pump shaft had 2 additional holes to allow for an increase or decrease of quantity of fuel delivery. \\ Factory setting for the pin was the center hole. | + | |

+ | ===== (B50A) ===== | ||
+ | L1976 27153-76 Sportster '76 only' Keihin butterfly carb. \\ | ||
+ | Float bowl (27395-76). \\ | ||
+ | Accelerator pump (27364-76), inside casting# (1-2). \\ | ||
+ | It has a solid choke, meaning that the choke plate (butterfly) has no spring action in the linkage. ((Dr Dick of the XLFORUM http://xlforum.net/forums/showthread.php?t=1035453)) \\ | ||
+ | You can begin to identify -76 only carb cause there is no plastic pieces on the choke shaft. \\ | ||
+ | It also has a idle mixture adjusting screw that was not hidden under a plug. It was rite out in the open where you can get to it. \\ | ||
+ | That is what you can tell from the outside. \\ | ||
+ | {{:techtalk:ih:carb:l76_keihin_carb_1_by_ddddylan.jpg?direct&300|}} ((photo by DDDDylan of the XLFORUM http://xlforum.net/forums/showthread.php?p=4428805&highlight=keihin+bowl#post4428805)) {{:techtalk:ih:carb:l76_keihin_carb_2_by_ddddylan.jpg?direct&300|}} ((photo by DDDDylan of the XLFORUM http://xlforum.net/forums/showthread.php?p=4428805&highlight=keihin+bowl#post4428805)) \\ | ||
+ | |||
+ | The real scoop to tell if it's -76 is on the inside. \\ | ||
+ | Inside, there was no hole drilled between the main jet well and the low speed well to feed the low speed jet. \\ | ||
+ | That made it the only one that didn't use the low speed jet rubber plug you see when you take off the float bowl. \\ | ||
+ | This hole can be seen when you remove the rubber plug and look at the wall between the wells on 77 and up Keihin butterfly carbs. \\ | ||
+ | 77-up carbs have a hole to connect the low speed well to the main well. 76 only had no hole. \\ | ||
+ | If you have a 76 only and install rubber plug, your bike won't run. \\ | ||
+ | In the float bowl, the accelerator pump discharge nozzle has a .040" orifice, (stamped 100), as apposed to the .031" (stamped 75) used on 77 up. \\ | ||
+ | But most importantly, it didn't have an accelerator pump "relief" port. You can observe the relief action (if you have a 77-up bowl). \\ | ||
+ | Remove the bowl and the "L" shaped linkage that actuates the pump. Drop the "L" into its hole on the side of the bowl. \\ | ||
+ | Pour enough fuel in the bowl so that you have it about 1/4 full and actuate the pump by depressing the "L" link (don't squirt on yourself). \\ | ||
+ | On the 77-up, there is a little hole down on the bowl floor that fuel squirts out of, as well as the brass nozzle at the gasket surface. \\ | ||
+ | The quicker you press, the more goes thru the "relief". \\ | ||
+ | All "relief" bowls have a steel rod installed under the discharge nozzle. This rod is free in its movement and you can hear it if you shake the bowl. \\ | ||
+ | This rod acts as "variable" resistance to fuel flow to the actual discharge nozzle. \\ | ||
+ | If the pump is actuated slowly enough, all fuel will exit the relief because there isnt enough force to lift the rod. \\ | ||
+ | |||
+ | '76 only' didn't have the rod at all. Instead, it used a check ball assembly in the small cover that is screwed onto the bowl (the one with the 3 holes). \\ | ||
+ | When you shake the small cover when it's removed from the bowl, you will hear the ball. There is no ball on 77-up. \\ | ||
+ | '76 only' has even more differences but those are the biggies. \\ | ||
