just get some tire irons and do it yourself, not too hard, just have to be patient. there are some decent vids on youtube to help you out, just be careful not to pinch the tube, put some baby powder on the tube so it doesnt bind up, run duct tape over the spokes if you want to create a little barrier between the spokes and tube, its a better alternative to the little bands that run over the spokes.
just take your time, if your're struggling, you're not doing it right. i remember doing the tires on my brand new kx250f, that was a pain because i didn't want to scratch my black anodized wheels
speaking of tire irons, i need to figure out which one of my friends have mine, lol
