Theres a crack in my fatty pipe about 2 1/2 inches long and about 2 milimeters wide. It's right near the spring-mounting hooks close to the engine. There is a minor amount of smoke that comes out when standing still but its not that much and when i ride it for a while it seems to go away. Im going to have it welded but was wondering if it will cause damage to the motor by riding it that way?
