We run a Jr Predator class, remove the governor, oil sensor. Top plate with fuel pump, green restrictior. Stinger clutch with blue springs, 16 driver. It doesn't seem to make a difference what sprocket gearing I put on, the cart has no speed. Can't even keep up on starts, or through the race. We are constantly getting lapped. I don't expect running away, but I just want to keep up. Any thoughts or suggestions appreciated.
