new 109 owner. I`m about ready to do my first 600mile service. The owners manual states for oil filter tightning, take the filter down until the gasket touches, then 2 full turns. Is this correct? I`ve never did a filter change on anything that requies 2 full turns. Also on this subject, I`m interested in recommendations of oil type to use. I currently use honda hp4 blend for my goldwing, and wonder if that is not also a good choice for this bike. Thanks for advice in advance!
