Hi Everyone.
Not to kick a dead horse but I've decided to get lower compression pistons. Just sold the old ones on ebay. But my dilemma is do I need to have the whole rotating assembly rebalanced or just the new pistons. The pistons are about 100 grams lighter that the previous ones. Any help would be appreciated

I'm not positive on this. If i'm wrong then I'll be corrected by other members.
If I am correct, the weight of the pistons shouldn't effect the balancing of the rotating assembly. I don't even think they use the pistons and rods when balancing the crank and etc. As long as your new pistons have been balanced (all being of equall weight) and everything else has already been balanced you should be ok. I have never participated or even seen a rotating assembly being balanced, so I may be bass ackwards from what this should be.

This is off topic and should be in it's own thread. I believe that the calculations they make do include the weight of the pistons. When my engines have been balanced they even wanted the rings and rod bearings. They also machined the pistons and rods to make them all the same.
