i seized the big-end bearing on my 1997 CR80 and i was wondering if anyone has some tips on rebuilding it...i´m gonna have to split the cases. Should i pay to get it done or attempt to do it myself (i know exactly what i´m doing i just don´t know how expensive it could be)thats the problem i barely have enough for the new bearing and i will probably need a new rod, i need new clutch plates, sprockets and chain, along with new plastic and get some broken bolts tooken out and replaced, but anyhoo i would appreciate it if i could get some tips on the work...then i´m gonna sell it and get a CR250 or CRF450, depending on how long the 4 would last...later random people :D
