Scott,
I won’t speak for anyone but myself…
The questions you are asking would be better asked at the track while hanging around the pits. That is how I started and everyone was very knowledgeable and patient with some of my silly questions. I am not busting your chops but some of these questions would be best asked there since they are very generic questions you are asking. Better to listen and read what is being written in this forum than answering each and every question. Just my opinion. 😆
Come on by at IMI and I’m the tall guy with the rotax. You can’t miss me since I think I am the tallest racer here in Colorado. Ask away! I might even have a beer with you. Or a root beer if you aren’t of age. And always at the end of the racing day 8)
By the way, how can you take a racing series seriously when they apply decals for the headlights :oOo Go Juan and F1! Go IRL and the Indy 500!
