Planning to winterize the bike soon and want to change the oil,.oil filter,..and clean the oil filter screen as per service manual instructions. It appears as though SAE 10W-40 would be the appropriate oil for my climatic region,..however I'm curious as to what brand names are recommended. Also which Type: API SE, SF or SG. There is also a mention of API SH or SJ with JASO MA,..as type choices. Any comments appreciated.
