okay this may be a stupid question but........ if i buy after market pistons and rods that already weighed eg.. (all 4 brand new rods weigh 250grams)
or (all 4 four pistons weigh 450grams) do i really need the balance the rotating assembly if the rods weigh the same and the pistons weigh the same? sry if this is hard to understand. or u can just tell me what is involved in balancing the rotating assembly. thanks man
