Looking online to purchase some top end parts for my 2013 rmz250 and i'm noticing some possible errors. For instance the 2013 microfiche shows the same part number as the 2012 for the piston kit but the 2014 shows a slighty different part number. I'm thinking that I need to order the 2014 part number because I believe the piston changed in 2013. There seems to be other errors like this on the 2013 microfiche too. Anyone else have any issues or notice this?
