I have a 92 Big Boss 250 6 wheeler. Just picked up a 92 Big Boss 350 4 wheeler for parts. In my conversation with the guy, he said I'd be able to swap the middle 22" wheels with the 25" from the 350 and run on 4 wheels until weight in the box pushed it down to run on 6 again. Didn't work. Rear shock just keeps pushing the backs farther down. In retrospect, I'm thinking that this might put too much strain on the bearings in the shaft of the centers. Would it work to move the 25" to the rears and put the 22" in the center or will my weight push those centers down when I get on? There are a lot of sharp turns in my trail and dragging rears tears it up a lot, which is the reason behind this attempt.
