hello everyone. i want to rebuild my 1980 cx500c engine. i'm not looking to do a bottom up. i have the bike completely apart, down to the frame. she ran great before i took her apart. i would like some insight as to what i should change out and replace. i know there are alot of members here whom have embarked on this journey. i want her to be a solid reliable runner. thanks in advance for the help. two wheels are better than four.....
