Hone size Help

Im looking to by a flex hone tool... does anyone know what size and grit i need to get for a 2009 yz450f? they also sell one for nikasil application would this be better also

thanks

so i found that 95mm seems to be the right size for the stock bore. but still dont know what grit to use.

If you buy a Brush Research hone, the necessary oversize for the correct spring pressure on the abrasive balls is built in. Order the hone by the bore size, or 95mm, as you said.

Use 240 or 320, and avoid anything harder than aluminum oxide. Use the hone "wet":
