CONSTITUTION:A rear cylinder 3b is disposed further near the clutch 14 side than a front cylinder 3a. Exhaust pipes 17a and 17b extended from the front sides of the respective cylinders are extended in a manner to pass a position below an engine 2 toward the rear. A lubricating oil strainer 15 is disposed to a portion positioned facing the front of the upper part of the clutch 14. The exhaust pipe 17b of the rear cylinder 3b is extend to a position below the lubricating oil strainer 15 and the clutch 14. This constitution enables prevention of separation of the exhaust pipe of the rear cylinder from the rear cylinder. |
