Carb synch backwards?
When you are synching the carbs and you open the throttle shouldnt the oil in the tubes rise? Like it will be sucked into the engine? Once i have the tubes on and the bike running if i open the throttle or even blip it hard the oil in the tube goes down toward the floor. Like the motor is pushing air out instead of a vacuum in. Do i just need a lesson in physics or is something wrong?

It's like sucking on a straw with your finger over the opposite end. Your finger is the throttle plate, the straw the intake manifold, and you are the draw from the pistons. The more you remove your finger, the easier it is to draw in air, and the lower the vacuum is within the straw.
