That reminds me of a couple of things. Before the Sportsman 500 became an H.O., there were people using Scrambler 500 parts to make their Sportsman 500 into a 500 H.O. They replaced the 32mm carb with a 40mm, and swapped in the longer duration cam. I think the clutch was modified too.

There's a hill climb on the Bull Gap trail system in Michigan. You can ride hundreds of miles from there through other trails, but some people will go up and down the hill all day and never ride the trails. Well, it's one way traffic now, so they climb the hill and have to take a trail from the top back to the bottom, and ride in circles all day. Some of the ATVs climbing the hill have extended swing arms and wide axles, etc., so they wouldn't even fit down most parts of the trail, and would have problems on tight turns. Their sand paddles wouldn't be that good on the trails either. Speaking of one trick ponies...
