Hi guy n gals im new to the xt660z and recently got 1 as a second bike and being and bit of a tinkerer I also got a pair of leo vince cans for it but after fitting It cracks and bangs VERY loud and im not a fan so after looking around interweb read a lot about "blocking ais"

Anybody got any pictures on how best to do this?

ps its a 2009 xt660z

cheers
Tony
