Hey all ..

When I rebuilt the top end of my foreman, I saw that the Rod attached to the piston was a bluish tint . . .
Is that normal, or it is caused by overheating !?! ..

Anyways, I'll keep it like that until it breaks.. I just want to know . . .

 

I don't know if the foreman has a press pin rod or not? If it does, it could be the factory heating the rod to get the pin in?
