Honda NSR125R damaged by foreign material. FOD, FME.

This is a bit of a random video. Basically i am helping my nephew rebuild his motor bike engine. It's one of the last Honda two stroke engines and my nephew is keen to get it up and running and restored it to its former glory! The Honda NSR125R is a bike typically used by young riders who will have thrashed it to an inch of its life! Then tried to repair it...... So this video shows what happens if you get foreign material into and engine and the damage it can do. Foreign Object Damage. Foreign Object Debris. Foreign Material exclusion.
