The "early" pre 98? 600’s, had forged pistons that make the horrible slappy noise when cold, not that it gets much better when they warm up. Sounds like the insides are trying to get out, most will tell you "they’re all like that". If you pull it apart, chances are there will be not a lot wrong with it, Just very short pistons, the issue can be almost cured by replacing the piston on that cylinder with the cast piston from a later model ( which supersede from the early ones anyway ) pistons are not different front / rear, either will fit into either barrel

So no reason you couldn't swap front to rear but you'll prob need a set of rings and after a few miles it will be noisy again

Pistons still available from Ducati Part No 120.2.042.4A but not cheap £248 each

Maybe JE or somebody will do a set
