my dealer and other mechanics say to leave the old filter in. it will catch any debris and even more importantly it allows oil into the top part of engine. been told that without the filter the oil won't go to the top end or will have very little flow.be sure to flush without the oil filter. Keep doing oil changes till it's back to honey.
I had water in my oil many times with my old foreman 400, all I did was change the oil 2 or 3 times then put good oil and new filtre in. the oil was a little white, after that I would ride it for a 1-3 hours and the heat for the engine always made the oil come back to normal, It must just evaporate the water. I sold the bike at 14,000 km and no problems.i was playing in a water and bogged out ive drained the oil 2 times but i still have milky oil what should i do..... any advice would be very thankful......
dito, run diesl fuel w/o changing filter for a few seconds. Flush and run some cheap oil for a minute or two. Change filter and put good oil in and your done.dump diesel feul into the engine and flush with that
Just to anyone who is worried about using regular auto oil, Ive used Castrol 10-40 ever since I bought it new in 01 and the clutch is still grabbing strongput in Honda oil or what ever you use as long as it is not standard automotive oil. That will cause damage to the clutch plates if used over time. This is a method and not the only method.
