Dropped the oil. No metal what so ever. Haven't checked the spark plugs. There is new oil in. The noise gets a little louder. I'll actually film a video nothing so you can hear.

What do you mean by loose bracket?

 

You said you swapped the motor. Maybe whoever did it forgot to tighten a bracket on the motor. It has happened to me before. Check around the motor to see if any thing is loose or is wobbling.

 

watch its his timing its too advandced and he's only pinging instead of knocking

 

It doesn't get louder when revving. It stays mono and just goes faster. Light knocking that is.

 

dont feel so bad, i rebuilt my engine completly and ran it and fried all my new bearings in 20 mins. didnt clean engine enough and all the metals got into everything and ruind it
