I've owned Lord knows how many karts over the last 62 years, and none had grease fittings in the kingpins. Most karters feel that excessive grease holds grit and wears the kingpin bolts. A SMALL squirt of oil before a weekend of running is all that's needed. Kroil is perfect, as it wicks into the space between bushing and kingpin. It's also great for steering shaft bushings and throttle/brake rod and pedal pivots. TJ
