Warning: while reassembling the carburetor one should bear in mind that front and rear carbs are NOT identical in all their components. Because of different cooling of front and rear cylinders regadring of their position in V-twin configuration, front and rear carbs in block do have different jet needles and main jets. Other carburetor components (needle jets, pilot jets, air pilot jets) are identical for both carburetors.
