i definitely remember the name Mark Powell
i stopped about 98 after a MX injury but i was still going to Rissi every meeting as mechanic for a mate who was racing 125's Mark Todd.
he won most of the club meetings there for a while including the Midland Championships one year
just had a quick look on the Rissi site but the results archive only goes back a year
hardly an archive
i really liked Rissi, good track, great burger van really good club full stop
