Hi all, just asking the question as at the time Ive been removing the air filter box and throttle bodys to check what problem ive been having with hesitancy below 4000 rpm. (bike backfires on start up and stutters occasionally when pulling away) wanted to check my injectors and anything else that could cause this problem.after removing the air box, I found this pipe below which was on its own and not connected to anything and was just wondering if anyone knew what it was. personally I think it could be a breather pipe but just wanted to check before I carried on, see pic below.
