I keep reading about gearing. I hope it doesn't take me too long to figure it out.

I did make one discovery that should help me - I found that my brake was dragging. that little white line next to the tach that indicates when you're pressing the gas & brake gave it away. so I adjusted the saturation or something until it went away.

then I retried my go cart RoC race & my times were slower! that was later in the evening after a few beers though. so I'll blame it on that.
