Ive had a few people look at my crankcase half (the left side) and they have condemned one of the cracks as being fatal. At some point, my family had the bushing end bored out and an oversized bushing installed, and it cracked the drive flange( the part where the clutch housing attaches). Does anyone have any leads on a crankcase half or crankcase that’s repairable? Thanks!
