I have a very small track with a couple table tops and some burms. I want to add about 5 or 6 whoops in the back section. How far apart would you have the top center of each one. I would like to learn to just skip across the tops. I am an above average rider. Bike is a 09 KX250F. I'm thinking starting with the distance being the same as the distance from front to rear tire? To close?
