I hope your pride can take a whack, the KT class is the most competitve racing in the country, take it out to port Gawler, you'll soon find if your the quickest out there you'll be the slowest at southern!
When I stopped racing couple of years ago the Rotax was a dying class, the leopards are a much better option, so much easier to maintain, can go the whole season between rebuilds etc, much more reliable, and faster!
goodluck with it all, have you looked into joining the Barrossa club, I wish I did, alot more down to earth bunch out there.
