Actually that’s is a Chinese engine transplanted into it, the Chinese engines is not a copy of a Yamaha FZ-16 they have 150cc engines.
Here is a thread on the swap on an Indian forum….the individual paid $1,300.00 for the engine. Bought direct from the factory and had is tagged with his original engine serial number…tsk tsk.
