I don't find the dynamo of my bike as a part like battery,when i remove some parts (exclude engine parts),where is this situated,does we can change it or alter it to next level dynamos
You fail to identify what year, brand, and model. Those facts would be very helpful to understand your question. A dynamo is also know as a generator or alternator. They are usually mounted on one side of the engine on the crankshaft center-line within the engine case or side covers.
