The Keihin number is stamped in the flange. \\ |
+ | The best way to identify a 79-up Harley Keihin carb is to read the Keihin number. \\ | ||
+ | It's the first 4 characters stamped on the (R) choke cable side just above the bowl. \\ | ||
+ | The HD part number on some models is on a sticker placed on the top of the carb. \\ | ||
+ | Older carbs either weren't labeled or the sticker may either be missing or unreadable. \\ | ||

+ | The chart on the [[techtalk:ih:carb01#sportster_keihin_carburetors_by_year_model|Basic carb information page]] has the factory jetting information for Sportsters. \\ | ||

+ | ====== Sportster Keihin Butterfly Carbs ====== | ||
+ | |||
+ | ===== (B50A) ===== | ||
+ | L1976 27153-76 Sportster '76 only' Keihin butterfly carb. \\ | ||
+ | Float bowl (27359-76). \\ | ||
+ | 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. \\ | ||
+ | |||
+ | The JP Cycles Deluxe Carb Rebuild Kit (4000050) will work. ((DeeDay of the XLFORUM http://xlforum.net/forums/showthread.php?t=1035453)) \\ | ||
