Intake system for saddle-ride type vehicle

An intake system for a saddle-ride vehicle wherein an engine body disposed between a front wheel and a rear wheel is mounted on a body frame, comprising:

• a rear shock absorber installed between a pair of left and right frame members disposed behind the engine body and constituting part of the body frame, the rear shock absorber extending vertically between the body frame and a swing arm that is swingably supported by the body frame and pivotally supports the rear wheel;
• and
• a cleaner case for an air cleaner and intake air control means are connected via a connecting tube disposed to bypass one side of the rear shock absorber, the air cleaner being disposed behind the rear shock absorber, the intake air control means being operative to control an amount of air supplied from the air cleaner to the engine body;
• wherein the connecting tube is formed to include a tubular main tube portion and a funnel portion, the tubular main tube portion being connected to the intake air control means at the downstream end thereof, the funnel portion being integrally connected with the main tube portion and formed in such a funnel-shape that broadens as it nears the air cleaner from the outer circumference of an intermediate portion of the main tube portion;
• the funnel portion is connected to the cleaner case wherein the opening of the main tube portion on the upstream end faces a cleaner element of the air cleaner and the funnel portion forms a purified-air chamber on the downstream side of the cleaner element together with the cleaner case;
• the funnel portion is formed wherein the intake chamber serving as part of the purified-air chamber is formed at least below the main tube portion;
• and
• drain means for discharging a liquid intake air spitting component collected in the intake chamber is connected consecutively to a lower portion of the funnel portion for communicating with a lowest portion of the intake chamber.
