Hello fellow bikers. Ive just finished rebuilding my 72 commando and must say Im pretty happy with it! Because of work load over the last few weeks its been sitting and has wet sumped. Today when I drain the oil from the case I find a disturbing amount of debris in the oil. After closer examination I discover that its fragments of the breather foam (part no. 062615). I then removed the breather body and find that the entire foam has broken down (nothing left in the body but for a few scraps). What now..........? My thought was to flush the case through the breather hole. With what.........? Has anybody ever experienced this before? The part was purchased from a reputable dealer. Any help or advice would be really appreciated. Regards, Ben.
Ben, Did the breather have the retainer discs (063116) installed? If not, this would allow the separator (062615) to bang around in there and was probably the reason for it's destruction. The big worry would be fragments in the drive side main bearing. I would leave the separator out and put it back together (On my Commando I don't have a separator installed, and have had no problems with it) and put a brake boost check valve in the vent tube up by the tank I would also recommend Valvoline straight 50W VR-1 oil your oil filter will catch anything that tries to get past it. HTH Cheers Dennis B
