I'm brand new to DRN, so I hope I'm doing this right. OK, I just bought my first KDX - it's a 2003 220 and I already love it. I've already done the Gnarly pipe and have some power reeds ordered. I've seen a lot of talk on the air box lid, but mine already has a large hole in it. Did they change this in 2003? Have there been any/many changes from the 2002 model? Any suggestions on frame/body guards? I'll eventually to the carb mod, but I would appreciate any other suggestions.
