Hi folks, after just ordering one of Kev's magic boxes to make my 09/10 XT660z run a bit "smoother" than it already does I have another thing I would like to sort out.
The bike seems to pop & bang a lot from the exhaust which I'm led to believe is normal anyway. It is totally standard but would prefer not to have this noise.
I read somewhere (can't remember where now) something about to cure it to block off the air injection system with an m10 cap screw & the popping/banging goes away.
Is this correct & if so can anyone tell me where exactly I can find said hose to "block off & if I do so will it effect the running of the bike in any way?

Ta muchly

P.s The popping & banging from the exhaust doesn't affect how the bike rides in any way, it's more of a preference for me, thats all.
