Hey there guys...I know I have not posted any pics of my k4 build in a while, But I have been slowing working on the project when the time and money arises. Pictures will be posted soon...PROMISE. Well my question is when rebuilding the front master cylinder (stock unit). Should I buy a hone and clean up the inside?? There is some slight staining in the area of where the piston sits inside. And glazing, but piston was not stuck. It seemed to work, but have not used it on the bike yet...Ideas??
