Hi, trying to figure out the best gear ratio for my sons kart. He’s running a 12/72 right now and seems not to be gaining any speed. He’s racing today so we will check rpms. Thinking we need to drop the rear a lot. Some info about us;
dirt track, some banking. About 1/10 mile.
we run a predator 212 with green slide. What is the max rpms on that? Or how do I figure that out?
he runs a caged kart. QRC. On Burris treads. He’s 5 years old.
what should gears be? Gear ratio? Should I change driver at all or keep a 12? Just play with rear sprocket till I find best rpms? Thanks for your help!
