hey guys!!

Hey guys I am new to this site. I have a 2000 Honda XR200R. It is all stock and has treated me pretty good so far. About a month ago it started to put out some blue smoke. I have been told by many people that it will most likely only need new rings. How much would a new set of rings cost? And how hard are they to install? I will be rebuilding it this winter. Any help or comments would be greatly appreciated!
