Have a 05 yzf450r that has issues. Why does the header pipe get glowing red and pops very loud when throttle open. I have tried everything from jetting, valve adjust. still pops and gets red. Any ideas?:)

This will happen anytime you are not riding the bike my 04 will heat up like that in a heartbeat if it is being run on my stand.

What about the back firing issue? Loud (ear piercing)popping when throttle open.

You are probably lean let your fuel screw out a full turn and see if it improves and check for an exhaust air leak-most likely at the header.
