Posts: 3 Thanks: 0 Trader Rating: 0 ![]() | crack on exhaust mount on crank case Hi All, I have a 126/650 engine I have just pulled apart and notice after doing all the work that the engine exhaust mount is broken. on closer inspection the case itself is fine and no visible crack internal. what would people recommend would be the best cause of action to repair this? do I just screw in a stud and mig weld with aluminium ? I want to use the engine for street use and replace the existing 600 block that's in it today. what are the best bang for bucks to do? I was thinking on oversized piston cylinders, but I don't know what the follow on requirements are for that. eg. cam, drive shaft piston rods..etc
