This will be quite a long post, to see it all, click “Continue reading” below. A while back I promised that we would upload a walkthrough on rebuilding the carburetors, here it is! This is a rebuild of the AS1/AS2 version of the carburetors, but the AS3 and most other versions are similar. To view a larger version of any picture, click on it.
There are still a few things left to do. First, the throttle has to link up to the carburetors. We haven’t shown that in this update but I’ll just go over a few things: first of all, the cut out crescent on the throttle valve has to be facing the opening towards the air filters, away from the cylinders.
You also need to adjust the fuel and air mixture. A good starting location is turning the adjustment screws all the way in and then 1.5 rotations out. Again, adjust as necessary.
In order to set up the throttle, first make sure the throttle valve is at the very bottom of the cylinder by lowering the adjustment screw. Then adjust it on idle so it runs evenly. We will show all the setup and adjustments in a video, once the weather allows for us to bring a motorcycle outside. Once the video is online, I’ll add a link to this update!
