chill out out bro, in any racing sport.. its the person with the most money wins. when i was there it pretty competitive for fucking 9-10 year olds. my dad threw down a couple grand on making my engine solid and fast. it totally fresh and was pretty stout. i used to place 2nd to 5th place after he did it. overall i miss kart racing and wouldnt mind buying a shifter kart sometime soon.
p.s the guy who bought the kart after we sold it, use to win every race, until he wrecked the kart in a nasty crash.
