weird popping sound from my 3TC exhaust

[CHB]

i have a spare 3T engine that i put in store for quite some times.. i have an idea now. my current inner springs all in good shape. so should i just get the out broken springs and replace them all with the those on my spare 3T head? it won't cause any future problem like what happened to my double valve springs from 21R right?

If you have another spare motor then certainly use the outer springs from this first.

However if you break another spring then I would suggest a new set.
