Ian: Assuming you are talking about the full body Yamaha/Piston Port classes such as WKA Sprint (or Piston Port Sprint for AKRA) – if you are up to snuff per WKA rules you’ll be fine for an AKRA race. I don’t know of anything you would be called out for. My little team has been running these sprints in WKA for years and more recently also at AKRA races like Mid Ohio and no changes are made. Come to the Pitt race and have fun!
Edit to Add: WKA now has the backup throttle spring rule that I don’t think AKRA is requiring (yet) so that is something I know we will have to add before Daytona (note to self . . . )
