Once I get the "air/mixture screws" at "3/4 turn out from full in", am I supposed to start the bike and then adjust an air/mixture screw on one carb to get the engine idling as fast as possible (with this adjustment) and then adjust the screw on the other carb to where the engine is idling as fast as possible (even faster than when I adjusted the first carb)? It seems like the bike will be idling pretty fast at this point.tbpmusic said:Next, adjust your “air/mixture screws”. Usually, 3/4 turn out from full in will be a good place to start.
Adjust back and forth for maximum rpm, on each carb. If you end up at some extreme, like all the way in or 3 or 4 turns out, you have a problem somewhere in the carb - probably indicates a good cleaning is in order. These carbs must be kept scrupulously clean to work properly.
Then, with the engine running, I adjust the "idle screws" to get equal strength pressure pulses from both exhausts. Are the "idle screws" the screws on the "flippers", and is this the point where I adjust the overall idle speed to an acceptable level (12000-15000 rpms)?
