You should do it yourself,its not hard at all.Ive never had an rm myself,but surely youve got a manual that explains how to do it,along with the bike?I really cant think of anything that could go horribly wrong.....Loosen the locknuts on the shock spring before removing the shock,also loosen the fork caps on the fork legs before removing them from the triple clamps.Be sure to torque the bolts on the forks to specs....if you dont have a c-spanner for the lock rings on the shock,you can use a punch/screwdriver and a hammer!
