I have a pretty new 2005 YZ450F. I am still learning how to properly maintain it.. Today was my first time removing my chain.. I am cleaning it in Kerosine. I am going to remove my shift linkage and give it a lube as well as my front tire.... What can I do to get rid of the nasty rust in that bolt.. and keep my sprockets nice and clean?? Doesn't seem like Simple Green 50/50 will be enough.. Any info/links will be appreciated!!! Thanks.
