I'm getting a used crank shaft and do you guys think I need to balance it? I've heard Honda cranks are pretty balanced out of the box and dont worth it to balance it? what are your opinion on this? Also my rods and pistons on my car was balanced...since I took them out for rebuilt, do I need to rebalance them when reinstall?

 

I never got mine rebalanced...they had to reweld it and reshave it because there was a spun rod bearing.... Haven't started her up yet though...
