I just changed the oil on my DR650, manual says 2300ml w/o the oil filter or 2400 with. I removed the oil filler cap, drain plug and let it drain for at least 5 min. also tilted it off the side stand to get all the oil out & changed the filter. I added 2300 ml and started the bike (idle only) and rechecked after a minute and was like :eek1 the site glass was completely full. Had my son and wife both hold the bike up to be sure it was level and I ended up having to remove 350 ml of oil. So where did the extra oil come from?
