We used to race a lot of the TT nats with a built 90 cvt with a 28 khein. It ran good on top but I could never make it respond off the bottom like I wanted it to. One day after many jetting and testing runs with no improvement I pulled the stock carb(24 mikuni) off of my son's KX65 dirtbike for a try. It was a huge improvement on the bottom without any noticeable loss on top. So I guess I said all of that just to say this....... Go with the 24.
