Hello, I'm a new member. I have taken over a 600ss, and upon investigating a sound that was said to be 'piston slap', discovered a severely worn piston boss on the horizontal cylinder. Bothe bosses were worn oval, by about 0.8mm in places.
I wonder what may have started this surprising wear, given that gudgeon (wrist) pins are meant to be sacrificed to the piston boss.
Q1. Do you know a supplier of aftermarket 600 ss pistons and do you have recommendations as per design options - I'm not particularly looking to change the standard compression - standard would do, but perhaps they have improved for wear on the boss... Pistons are not available in matched pairs from Ducati, only singly with vertical cylinder.
Q2. Is it Ok to simply hone the cylinder and fit a new (matched pair) of pistons.
