I am sure you guys would appreciate this and don’t know if its a repost but these guys hold an annual 500cc day in Holland every year. If you search through or watch the youtube vids you will find a number of them from 2007 to 2009. The earlier versions start with filming in the pits and the classic big bores then a practice session.
I am bias but nothing sounds better than a bang of a single cylinder 500cc 2 stroke at an awaked idle, and when fisted the bark under load.
You will notice the ruff running when cold with a gut of oil in the crack case that hasn’t cleaned out yet.
Some of these old dudes pinned them.
