spray paint a wiffle ball black and put it in the exhaust or something similar

Most likely cause of the backfire is that the head pipe or the "slip on" pipe is not sealed. When throttle is closed any leaks allow air to enter the pipe, this creates hot lean exhaust along with lots of backfire. Check the pipe front to rear for good clamping and especially the gasket at the head.
