catching

Hi guys , ive got a 2002 mille with a full akrapovic 2into 2 system on , and noticed the chains been catching the left hand link pipe , wondered if anyone else had a similar problem , chain is adjusted correctly , i have an ohlins remote preload shock on it so backed that of a bitg thinkin...

Hi guys - ME AGAIN went out yesterday with the missus on the back problem is the chain was catching on the exhaust link pipe (centre piece) is that because i didn't have enough preload or could it be slightly bent pipe catching enough to make a noise and leave a mark photo to follow
