So i was riding today and my front sprocket came off and went down and broke off my shifter from the case where it goes in. The shifter is still attached and it still shifts but all around the area where it goes into the case is where it broke. Would it be okay to weld it back together? I have access to an aluminum welder so the type of metal aint the problem. If welding is not an option, what is the best thing to do? Thanks in advance guys.
