Would risk s**t flying in then wouldn't you? I have thousands of mountain foothill miles on my staton hd 3 pad clutch with such a small amount of wear, dust is beyond negligible. The original clutch would maybe last 500 miles without modding the springs.
Edit: that transfer case and stock sprocket's gear ratios don't allow the clutch to stop slipping till like 18mph on a 26" rim, so to make it last longer without different parts or mods is to just stay above 20 at all times...i have a 20:1 gear ratio so i don't really have the issues you'll see.
