Proper club racing as it should be. I used to race air cooled single cylinder 250's back in the early 80's when water cooling was really becoming popular. I even welded a water jacket around a air cooled cylinder but gave no real noticeable performance increase round the Cadwell short circuit which was 1.35 miles long. I would love to build a high spec air cooled single with large cooling fins like the MZ for Cadwell and turn the clock back and race it.
Hi Paul, they normally vary between 26 - 28hp. The MZ race regs allow only a slightly modified expansion chamber and new to 2017 is the addition of Minkuni carbs. They will still carry over 100mph through turn 1 at cadwell
