This is a 70cc racing engine, so it does not have an electric starter or oil pump. The engine has been tested for leaks and is completely sealed. The Euro 1 stator has been tested and shows correct values. The engine also does not leak gear oil.The engine is a 5BM, i.e., a Yamaha Jog Space engine, but it can also be used on JOG FS, AS, Aprilia Sonic, and others.

Note:
The engine block is generally in good condition, with a few remarks: the engine number is worn off, one gear housing thread is loose (requiring a nut on the opposite side), part of the thread for one exhaust stud (M10) is broken, some kickstarter threads are slightly worn (requiring longer bolts and possibly a nut on the opposite side, with space available), and a center stand cannot be mounted on this engine. These issues are largely inconsequential if the provided instructions are followed. See the pictures.
