Hello!
First, please try to understand my english, ėtīs not my mothers language...
The problem:
My friendīs ducati (600ss 1994) got itīs motor totally jammed during normal freeway cruisig! Rear tire went locked in 100kmh speed! Clutch works fine and gears go in and out => so we think itīs piston that is jammed.
I tok the engine out of the frame and cylinder heads and pistons and barrels too (there was little marks on horizontal pistons leaves but barrel came out easily) but engine is still jammed, nevertheless it wont spin if I tried to spin it!
What could I do next???
