Wrecked bike last year on the left hand side. Cracked stator cover on the very bottom. Ordered a bunch of the parts and went to take off the stator cover and saw a hairline crack above the bottom bolt. Talked to a welder as well as a good friend, going to go with an aluminum epoxy bonding agent. Above that bottom bolt is a brass bolt connected to the crankcase housing. What is this and is it okay to remove to bond the crankcase back together? Thanks for your help.
