So, it seems the advice I am being given is :- Give Up! Throw the pistons away! This is different to my experience on similar forums in the past, where people made suggestions about how to make things work.I am still no further on with the original questions. What rings should I buy?If I was to buy another barrel or sleeves, what would be the recommended fitment by Yoshimura?Maybe nobody on the forum has any real experience of fitting secondhand Yoshi pistons so can't help. I am feeling a little discouraged at the moment.
