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.

+ | This carb will be fine on an 88" motor. Here's the basic stuff you need to deal with. \\ | ||
+ | Manifold: use the Super B or Super E manifold. \\ | ||
+ | Air Cleaner: the entire Super B setup is a bolt on to L series. \\ | ||
+ | Throttle: this goes to the action cable of the 2 cable system. Forget the idle cable exists for now. \\ | ||
+ | All sportsters 1972> open the throttle plate when the inner cable retreats into the outer coil. \\ | ||
+ | In other words, the braided cable 'pulls' the throttle plate open. The L series (except mgl) is set up for the 1971< throttle plate actuation. \\ | ||
+ | In this setup the inner cable was not braided. It was a solid wire because the inner wire pushed the throttle plate open. \\ | ||
+ | You need to reverse this action at the carb. | ||
+ | For instance: \\ | ||
+ | 1st get a Super B throttle shaft and install it in the GAL. It's longer on the forward end compared to the GAL shaft. \\ | ||
+ | The added length will allow you to install a second throttle lever assembly on the longer shaft. This lever is also Super B. \\ | ||
+ | See the first pic below. The shaft extension will be less (but still enough) on a GAL. \\ | ||

+ | 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. \\ | ||
