Backfire out of tailpipe
I've had this problem ever since I replaced the cam. It's a stock grind cam. It runs fine with great power and so forth but when i let off of the accelerator, POP! it releases the backfire. What can be causing this? It's tuned, timed, and carb adjusted. Can it be a valve is too snug? Please help!

Any exhaust leaks up close to the engine? The introduction of fresh air via exhaust leak on deacceleration will also cause a backfire.
