I'm new to the site and have had a passion for speed for many many years, along with many speeding tickets. I've decided to take the speed off the streets and to the tracks. I'm going to be running a 1981 Kawasaki KZ750 (4cyl) that has been slightly modified both chassis and engine so what class would I run in? M-PG or M-G? and also is there a current record for a Naturally Aspirated and air cooled 750cc motorcycle or is all 750's air/liquid in the same grouping? and what is the current 750cc N/A record?
Thanks,
Tristan
