What is the oil capacity of a 1986 Suzuki Intruder 700?

About 3 quarts. Add two quarts and then start the bike briefly and then add the necessary oil to the middle or top line on the sight glass. Also, the oil filter is a PH6018 if you buy a Fram filter.

NO. The oil filter for a 86 is PH 6016, the 87 is PH 6018. It is a different millimeter threading on the filter. The engine take 2.5 qts without a filter change and 3 qts with a filter change, however it should be a little over half full in the sight glass.
