Sorry I forgot about that bit...

...yes...

Wrist pins are all the same weight at 108 grams.

I can't see 10 - 20 grams of weight difference in the rings which are still fitted. I don't want to remove them 'cos knowing my luck one or more will break and then I can't send them back.

I could indeed remove the obvious bumps but the inside of all of the pistons have been nicely finished - there isn't anything obvious to remove. The knobbly bit in the pictures on page one that was discussed previously has a weight about 2 grams (I know that from arsing about with my older M102.910 pistons).

{Please don't make me explain why I've bought new pistons!}
