That "bump" dissappearing would be nice!! i know i get good air time in my cr125 shifter when going over it!
I'm one of those saturday only shifter guys, i dont know other peoples reasons why they only come on saturday but i can tell you some of my reasons.
1: cost, cheaper to run on saturdays. plus i run my tires till they are pretty much shot, to be competitive against other shifters or TAG karts i would have to spend a lot more on tires and maintanence to have any chance of keeping up!
2: time, can get many more laps in a shorter period of time on a saturday. i dont have enough free time to spend a good portion of a sunday at the track. i can go down on a saturday and stay maybe 3 hours and get a good amount of laps in and still be back home to get the other things done i need to do.
3: kart racing isnt my main "motorsport", my main racing is i drag race a 8.20 second motorcycle, that pretty much sucks up a lot of my time and $$$. the kart is just a hobby to me. when my son gets a little older than i will most likely be spending more time at the kart track with him.
