Quads should not race first! it will make very akward lines for the bikes. if the quads go last then after the intermission the dirt could be good for the bikes again..
So how does this split program work ? Are the quads racing their first motos first and then the bikes, or are the quads racing both motos first, then the bikes race ? Will you prep the track in between the quads and bikes ? How many classes are you running (bikes and quads) and how many laps ?
this is how it goes.. racing starts... all quad classes will run their first motos, then they will do track prep, then all bike classes will do their first motos. then intermission.. then it will restart with quads doing their second motos followed by another track prep for the bikes second motos.
