just bought this 2004gsxr 750, has 3600kms on it. the previouse owner garaged it since the end of last riding season. what must be done before I can ride it again? the bike sometime has unstable sound, according to the owner that is because that he didn't use the fuel stabalizer. should this be a big issue? how can I solve it? thanx. and can't wait to see u guys on the road.
