Haven't done a top end for over 2 years and misplaced my manual. Which way does the piston face? One I have has no arrow on top. It's on my son's KX 85. Does the piston face forward with the two vertical pin holes and the oblong hole facing towards the carb? Which means the slots in the side marked with "in" go towards the back? Does this make sense? Is there a universal way to tell on all pistons regardless of mfg?
Also, how much play should there be side to side when you move the rod on the crank. There's just a little which doesn't seem excessive but thouight I'd ask anyway.
Thanks
