Just tuned up my carb and was over excited that t was finally running great. I popped the clutch pretty quick and heard a banging noise. The noise only happens with quick take off .
Does any one have any idea what it could be ? It sounds like it is coming from back of car. I pulled off the drive shaft and the yoke seems like it is set fine noy to much play in it .
Does anyone have any ideas what else it could be ?

 

Is your tail piping secured?

 

Going to put on lift tomorrow to see if any chance of hitting
Thanks
