Yes, Morton is still a 8hp "stock appearing" race, but the rules are loosening up, slide carbs~ n~ alcohol. Lol. ..That track is to small for anything bigger anyways. They have the room in the arena to make it bigger but they don't. It's tight and rough. ......handle bar country.
Kalama is the best big mower track down here. ...Nice, smooth oval. ..but a handle bar guy still seems to win
Amboy runs both classes but is a little bigger (and better, imo) version of track like Morton's
