Got back to putting the carb back on the 86 Big Red. Slipped the air tube on the back of the carb and dropped the air box in. Tried slipping the tube onto the box and it doesn't fit very well, the tube diameter seems just a hair too small and just a little short too. Went ahead and tried fitting the tube from the box to the frame and it was almost 3/4" too short..it will slip on to either end nicely, just too short. Once I lined up the airbox w/ the bolt holes its obvious either the airbox is different or the air tubes. Has anyone ever ran into this?
