hey tubes do yurself a favour take it too a pro and get it right,youve got a bunch of guys on here,(Note not everyone) who think they are mechanics throwing ideas at you and they have not even seen or heard the bike,whenever you ring a workshop the first thing they say is bring it in,because they cant guess what the problem is,you could say there is something wrong with the carbi only too find that someones shoved a potato up your exhaust,so if you got no idea take it somewhere that does,and before they do any work ask for a price and then you decide if they touch it or you take it home, a good mechanic will have agood idea whats wrong the minute they hear it
