A few years back we were running the Rotax series and had just purchased a new cylinder (can’t remember why) and installed it for a test day at New Castle. It was early spring if I remember right, we drove half way (5hr drive to NCMP) Friday night so we could get a early start Saturday morning. Arrived at the track early to a cold but nice day to test. Got kart out fired it up and water came running out of that new cylinder (cracked). Guess it got colder than we thought friday night at the motel. 10 hours on road,gas,cylinder,food, and family time together you gota love this sport.
