24 inch

Hello everyone Just joined today as I am finally putting my love of motorcross bikes and mounts bike together. I need to buy a rear disc sprocket adapter and was wonder what the best amount of teeth should I use as I'm riding it on a 24"

I have a 24 inch schwinn typhoon, Would it possible to put the 26 inch monarch 2 springer forks on it? How will this affect the ride? What if I put a 22 inch wheel on the front? would this work? How do you think this would affect the ride? What is the trail if you put the 26 inch monarch...
