80.6 piston is 2nd size over?

[Evan]

My pistons were put in 15538 in yr 1988. These say 80.6. Should be 2nd over stock? So sleeves can be bored again?

I think so - there are 80.8 pistons available. As you are in the US I'd check with Wolfgang.

We are talking about the 750. In the past i got 80.2 (1.) , 80.4 (2.) and 80.6 (3.) which are easy to find.
80.8 are not so easy to find. I have a new one 80.8 if you need one for fair 40 EUR + shipping. I have to look where I have stored the rings...
Sorry, the second one has only 80.6.

Wolfgang will have 81.0mm and probably 81.5mm Ross Racing Pistons in stock these days, very much doubt he has any 80.80mm Mondials left
