Kite, who matched the lowest nine-hole score of his career with the effort, ended the first round alone atop the leaderboard after Cory Pavin was penalised for an infraction.
Pavin's sixth birdie on the 17th had pulled him level but having hit a chip after his ball moved slightly when he grounded his club on the 14th, he was docked two strokes.
Bernhard Langer and Lance Ten Broeck were the major beneficiaries, the pair ending the first day of action in Michigan in a tie for second place, one shot behind Kite.
Pavin lay in fourth, alongside Fred Funk, Jeff Sluman, Tom Pernice Jr. and Mikael Hogberg after 3-under 67s.
"You probably haven’t read, but 60 is the new 40," said 62-year-old Kite, who has not won on the Champions Tour since 2008.
"This golf course is tough enough it will bite you," he added. "Nobody’s going to play 72 holes out here without having it jump up on a hole or two and kick them in the rear, and it got me on 17. There are just some places that, if you miss it, you’re going to pay the penalty."
