Congrats on the bike- you'll love it. I have an 07 KX 100 too. I am 5'9 and 180. I use it for riding with the kids. Check my sig- I also have a TTR125 that's been warmed up a bit for me too. Mini's are fun. Check out planet minis website. Not to knock your thread- I don't get it. In the some assembly required- are we dropping all "builds" here? I mean you just need to raise the bars, set up the suspension with springs and revalve, add a flywheel weight and off you go. You could do some other things too, but most fall into the bling category. Where's the build? I could see it if you were dropping a 125 into the smaller chassis or visa versa, (heck- I put a XR 200 into a KDX200 frame) but this is bolting on parts that most riders do anyway. Sorry to be a jerk- not trying to be- just wonder what this category is coming to.
