King's Lynn Stars promoter Buster Chapman says speedway needs to be simplified if it is to have a future.
The Birmingham Brummies went out of business in July but have since re-formed, while Peterborough Panthers' future hangs in the balance.
"The rulebook in my view is far too big and needs burning so we can start again," Chapman told BBC Radio Norfolk.
"That's not going to happen in the first year or two. But we've already made quite considerable changes."
Few teams in the country's top three leagues are financially viable and gates are declining, leaving the sport heavily dependent on its TV deal with Sky.
Meetings can often fall foul of the weather, with fans making wasted journeys, and the rules around riders' averages and team-building restrictions can be hard to follow.
"We need to make our sport more attractive and get out and promote our sport," said Chapman, who has been voted on to the British Speedway Promoters' Association managing committee.
The Stars are financially stable and attract some of the larger crowds in the Elite League.
But Chapman was angered recently when their play-off semi-final against Poole Pirates was postponed twice, and he expects the post-season fixtures to be brought forward in future years.
"It will happen. It will be earlier in the season. We knew it was an issue and had to be dealt with," he said.
