How to change the oil in Yamaha midnight star 1900

SOURCE: Yamaha 1900 midnight star how do i do an oil

Drain plug on the bottom center.
Site glass left side toward the bottom of the engine.
Usually just above or just behind the kick stand.
Warm up the bike first then cut off and try to level the bike as best you can. This will allow the old oil to flow easier and drain completely.
You should probably consider changing the oil filter while your at it.

Replace drain plug and do not over tighten!
If replacing the oil filter take some of the new oil and dip a finger into it.
Wet the gasket on the oil filter and HAND TIGHT only back in place.
Do not cross thread. If it does not go on easy back off and try again.
DO NOT FORCE IT! Refill to correct level using the manual for amount needed to refill. Use site glass to fine tune.

Crank bike and allow oil to circulate. Check for leaks.
NO heavy REVVING allowed at this point. Let the oil do it's thing for a few minutes.
Check oil levels again and add more if necessary.
Do this in small increments as you do not want to overfill.
THIS IS BAD. Correct level GOOD

Dispose of old oil at any local repair shop. Grease monkey or even some parts stores will dispose of the old oil for you.

Tip: Most of the oil catch pans will not fit under the bike.
And lets face it, most of us do not have a well stocked bike shop with a lift table. I used a 2" PVC pipe with about 16-20 inches long cut in half to make a trough. Use a small board, brick what ever to raise the trough up to the oil drain port. I put the catch pan just off the front porch and let the oil flow from the bike to the catch pan with this PVC trough.
Sweeeet.... worked like a charm.

Tip 2: Clay based oil absorbent to clean up any spills. Cat litter works good too.

Good luck!
