You will absolutely love riding at silver lake. My buddies and I headed up there in May for our first time. My one buddy on his Scrambler 500 and me on my 400ex. Check out the pictures in my website. Read up on the rules before heading out and plan on buying your dunes flags when you get there. Your stock atvs will do just fine on the hills, just don't expect to win many drag races. There is a lot of highly modded machines that run in the drag races and make stock machines look like they are sitting still. Have fun.
