Well... my d3r is getting worse rapidly now. When I hold it by the flywheel and let it drop through its compression it makes a bit of a gurgling sound and drop through it after about 10 seconds.

I took it apart, and the piston looks OK, without any scratches or whatsoever. The liner however clearly shows some damage on the chrome plating. 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)...
