The clutch may need adjustment..

It could be a clogged jet on your carburetor, it could also be varnishing in the float bowl possibly making the float stick.
Try cleaning out the carb with carb cleaner and blowing the jets with air, not too much air pressure.

4 small tubes from the bottom of the float bowls, are drain hoses and should be routed between the rear of the engine and the frame.
the 4 small upper hoses are vapor relief hoses and should be routed under the airbox.
The final larger hose or hoses depending on tank are fuel inlet hoses and will connect to the fuel petcock on the Gas Tank
