    Oilhead oil drain Q

    My 2000 R1100RT is apart in my shop for brake lines & routine maintenance including fluid changes and I want to change oil. But it seems a lot is trapped in the oil cooler etc since it was a very short trip and was cold when driven into my shop. Fuel tank is off & alternator belt removed.

    Is there a way to more fully drain it?

    There is no doubt that there are those that will disagree with me but if you take about a 20 minute ride to warm things up really good then park the bike on its side stand for about a half hour then place on center stand and pull the drain plug all, or most of the oil, comes out. I am assuming your bike has an oil temperature thermostat.

    With modern oils, it makes little difference if you change 80% or 90% of the oil, hot or cold. Just do it.

    Yeah - I understand from somewhere that only hot oil will drain back to the sump while parked. After posting, I decided that access isn't so bad but what I can get to the drain and filter after the tupperware is on, so it's going to have a short ride tomorrow.

    I thought maybe there was a fitting that could be cracked loose or something, but maybe that isn't such a bright idea after all.

    I should also have said that this method works very well on my '04RT I think because it has a thermostat but seems to make no difference on my '93RS probably because it has no thermostat.

    The warm up and side stand method you described is the only way to accurately check your oil level on the thermostat bikes as well. We've had loads of ahem... discussions about that here too!

    I respectfully must disagree. If you use the above oil drain/fill method then you need only go to the the center stand to check the oil level after a ride with engine at temperature. That's the method described in my '04RT owners manual and it works. Been doing this for ten years and the oil level always goes to the center of the sight glass with the oil cooler full. If you place it on the side stand after a ride then go to the center stand to check the level and the level is on the sight glass center dot with the oil cooler empty then your bike is under filled with oil. I'll bet you a mouth full of p__s and you can hold the bet.

    My 2000 R1100RT has a thermostat. I can tell by the excellent oil temperature control in service. The hot vs cold drain back issue is a revelation though. I was surprised by the low sight glass level after that very short ride across my backyard - and it never recovered after several days parked inside.

    There's something in the oilhead oil level that I don't understand then. Is there a guru reference? or an established guru opinion?

    Yup, do as described in post #7 and all will be well as the most you will be low is only about 0.25 quarts or maybe a little less which matters very little if at all and hardly worth discussion. Oh, and probably better than you'll get at a dealer either way.
