PURPOSE:To compactly arrange intake system parts and secure the capacity of an air cleaner sufficiently by inclining the cylinder of an engine nearly horizontally and arranging a carburetor in front of a suspension part of a crankcase and arranging the air cleaner on a power transmission case. CONSTITUTION:A cylinder 17 is inclined nearly horizontally towards the front of a crankcase, and a carburetor 66 connected at the intake upstream edge of an intake pipe 65 is positioned on the upper side of the cylinder 17, viewed from the left side part for an engine unit 11, and positioned in front of brackets 60 and 61 as suspension part. An air cleaner 67 arranged on a power transmission case 14 continuous to the crankcase is positioned behind the brackets 60 and 61, and the air cleaner 67 and the carburetor 66 are connected each other through a connecting pipe 63. Accordingly, a wide space can be secured between the engine unit 1 and a seat 9, and the carburetor 65 and the air cleaner 67 can be arranged in reasonable manner, and also the capacity of the air cleaner 67 can be secured sufficiently. |
