This may be because the chrome plating was never that good to begin with (see the photo I posted a few pages back), but it's quite clearly worn out a bit prematurely.

The engine has had about 6 to 7 litres of fuel through it and has always been tuned properly without overheating and a tad rich on the bottom end. Never has anthing but fuel and after run oil entered the engine... I don't know what I'm going to do with it now. Maybe I'll buy a new piston set for it or maybe I'll sell it completely (with warning to the new owner of course)...
