The metering circuits of these carbs are configured for the best 1/4 mile performance. No consideration at all was given for street operation or kick starting.

+ | There are 5 different versions of this 'type' made before the Supers replaced them and 2 more versions offered in limited numbers along side the Supers. ((Dr Dick of the XLFORUM http://xlforum.net/forums/showthread.php?p=3521940#post3521940)) \\ | ||
+ | Each of the 7 were tailored to different motor sizes and applications. \\ | ||
+ | Wrong one on wrong motor was/is a disaster in many areas. Throttle response is one of the problems. Although, the right carb on right motor was/is spectacular. \\ | ||
+ | |||
+ | The 'GBL' was the only one of the 7 designed to be a street carb that would match up to the specific requirements of a stock 900. \\ | ||
+ | It was also 'smallest' of the 7 and it was made side by side with the 'GAL' (biggest). Only 3 years these two models were sold (1972-74) with most being the 'GAL'. \\ | ||
+ | So these carbs are rare, expensive and old and that keeps them under the radar. Many got molested in the ensuing 37 years. \\ | ||
+ | But for the guy who does take the plunge and experiences the way his 900 runs with it puts the 'GBL' in the 'never sell' category. \\ | ||
+ | S&S sand cast carbs were made by us and for our bikes only (made by HD nuts for HD nuts). \\ | ||
+ | All the sand cast units share 3 things: | ||
+ | - No pump. | ||
+ | - The entire throat is precision machined from ac to manifold. | ||
+ | - They have long air column lengths with the discharge tube quite far upstream of throttle butterfly (they hit your leg). | ||
+ | |||
+ | The entire sand cast gasoline models. (may be out of order): \\ | ||
+ | * G - drag only, big motors. | ||
+ | * GA - drag with slight mods to make 'street-able', big motor. | ||
+ | * GB - same but for small motors. | ||
+ | * GAL - street carb, big motor. | ||
+ | * GBL - street use, small motor. | ||
+ | * Super A - 1st one size fits all, street use. | ||
+ | * Super B - refined Super A, street use. | ||
+ | * MGAL GAL - reintroduced with provisions for snap throttle street, big motor. | ||
+ | * MGL MGAL - with super style main circuit & two jet intermediate circuit, big motor, street. | ||
+ | * Super D - larger Super B, giant motor claimed to be drag only but circuitry is street. | ||
+ | |||
+ | The first 3 were race only carbs. The rest were street carbs with race tendencies. Mis-application of the first 4 was very common. \\ | ||
+ | G, GA, GAL, F AND FA series are all 1-7/8" butterfly. GB and FB series are both 1-3/4". ((mrmom9r of the XLFORUM http://xlforum.net/forums/showthread.php?t=1786621)) \\ | ||

+ | Here is a fabricated 2-1/4" version of an early G style carb (L) below. \\ | ||
+ | And a fabricated 2-3/8" which used a fuel pump with a Holley float bowl and accelerator pump (R). \\ | ||
+ | Ten of the 2-1/4" carbs and 25 of the 2-3/8" carbs were built. Both saw action in AMRA Pro Stock and a few of the 2-3/8"s on the streets of Houston, Tx. \\ | ||
