I went to my Yamaha dealership today to get an oil filter so I can change my oil. I would normally order online but I am strapped for time as I am trying to get it changed before Friday. The filter they gave me is part number 5GH-13440-60. I question it and they assured me that it is the filter. They one on my bike now is a -30. Is this filter correct? Will it work? Also an opinion question what oil do you use? Brand and weight?
