Piece of piss mate I did mine the other day. The hardest thing is getting the old downpipes off as they're a barsteward to get to. taking the tank off and resting it on a 25KG calor gas bottle next to the bike made life a lot easier.
I'm just waiting to get some pictures of mine before putting them up on here. The ***** that I am rode it before taking pictures and now it's dirty. DOH!
