I am probing the mysteries of this little bike. Korean, recently purchased, purple, and apparently they used to be branded Batavus. In general, it's in fine shape: the tires are fine and the paint is quite nice.
But I won't try starting it until I know everything that must be lubricated and adjusted. The primary drive is a toothed belt, which turns a countershaft. The countershaft is invisibly connected to the drive sprocket shaft through an overrunning clutch and gears concealed within the halves of the aluminum engine/transmission casting. I've been looking for a lubricant filler hole with no success.
The ignition seems fine, but I'm stumped by a big plastic box that ought to be an air cleaner but doesn't seem to contain anything but air. The air intake port on the carburetor is only about 1/2" or 12mm in diameter, and I'm guessing that the plastic box is some sort of resonator to improve performance.
There's some heat/fire damage to the outlet of the plastic box, which I can reconstruct. Is there an air cleaner on this bike? Is there any sort of lubrication procedure that anyone has heard about? Any other advice?
Thanks. Mark Kinsler,Lancaster, Ohio 43130.
