alright thats 3 votes, thanks fellas :thumb: Hopefully I can get a new copper before next weekends pull.
This makes me think it isn't a mechanical problem.It doesn't do it on the smaller tune. Just what could make that noise even if its a simple tune fix

Be glad you don't have a lb7!!!
That is a loose injector/copper washer on bottom. On my old LLY i had this EXACT same thing happen a couple times. Im sure if you look close enough you will see smoke puffing out around the injectors. All i did was pull the injector sand the copper washer and slap a new oring on it and good to go:thumb:
