LET piston size

[Wazza024]

Im getting my bottom end rebuilt and changing the pistons to forge. Am i correct in saying the standard size piston in a let block is 86mm? If so my piston got sent to a engineering company to be measured and they say it's 72.5mm which either they have measured it wrong.

Correct mate as standard, sounds like you've been sent the wrong pistons

Thought that was the correct size. The size they have give me are of my old pistons :wtf:

Yep 86mm it should be. If your doing a piston change why not go for oversized ones 86.5mm.
