| + | GBL \\ | ||
| + | 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. \\ | ||
