I am after a bypass valve for my 600ss, part NO: 1-000-700-031 which also for 888 & 900ss I presume other models but as always Ducati say this part no longer available. so if anyone got one they could sell me one please. My engine didn't have one, blanking cap and spring but no valve.
Perhaps try the original part numbers.... Cap 0660.49.010 Valve 0660.49.020 Spring 0619.49.178 As far as I can make out, they were the same on the 600, 750 and 900.
