i bought my 99 kx125 with the engine out of it because it needed some bottem end work. Now im trying to put the engine back on the bike but i cant get the swing armpivot out, it wont move at all. Is there anytricks to this, im sure im doing it wrong, any help would beawsome, thanks!

 

just spray a bunch of wd40 around the points where the pivot bolt goes through the arm, take the nut off and drive it out with a hammer & large drift or punch. (2 foot long pieces of rebar work good too)

 

thanks for the help, i finally got it the next day.
