I have no experience with them but I would love to give them a go if I ever had the money. I know on the CR500 they replace the Honda cylinder with a Liger cylinder as it's made for the large bore, there was talk about one being developed for the KX500 engine but I don't know if it ever happened. I wonder what ring life would be like on one of these engines.
