i just picked up 2 1989 yz125's for free... they both need new top ends i have a piston and rings for one of them but im not quite sure how to go about cleaning out the bottom end.. and the shaft looks to be a lil rusty on the very top but i should be able to clean that up.. the bottom end is still lubed but there looks to be some crud in the bottom end.. maybe run some oil through it ? btw this will be my first bike to work on.. my dad will be helping but any help is appreciated. :)
