Oilchange question.
 

So when a bike is standing in room temp all winter and its time for oilchange, is there any point starting bike and let oil get hot? In my mind the oil is all down in in the pan and in some hours everything is out, if i start it up oil is all over the engine and i think i would get less out. What is your opinion about this? Its question for a Yamaha Thunderace.

That's when I prefer to drain the oil , as you said all the oil is drained down. It just needs to be left dripping for a bit longer so the cold oil comes all out. I try to let the bikes drain overnight if possible, even a couple days since I have enough bikes to ride. Heating it up before draining maybe helps the "dirt" stay in suspension and drain better, but I think when left draining for long enough time it all comes out , or as good as any other way.

Either way is fine in my book.

If I somehow felt the oil should be dirty or not suitable for use, id drain it right away.

Well i dont like to break oil seals from can and fill up months from riding bike, for me its importan that oil is fresh when riding. Its no damage done in crankcase with oil done 2k sitting in room temp.

I think i will stick with my plan, let the heater oven warm up the pan ahead and let it be there when draining a day or two. Overkill but maybe best for engine is new oil when stop riding in autumn and new oil in spring.

I cant see any point, now. But, all winter... it is a lot of time. I really don't know how much oil will be left in the higher parts of the engine. Dry seals, bearings... until the oil pump build the pressure. I am starting my bike at least every two weeks, usually every week. Cold start (and maybe dry) is where the engine is under stress and suffer. Theory says ... I think.

Its ok to turn engine once a month, but starting it up i would not recomend if you dont let it warm all up and run for some time. What happens is that you get condensation inside engine if its not real warm, talking about bike outside.

I agree, and I am doing that :).

I dont have that option inside house ;)

Just did my oil change outside. Started the bike and let it run for about 10 minutes since temps were around 40 degrees. When i stored my bike inside i did not let it run however, just drained it and filled. Didn't seem to have a problem. As long as you give it at least 5 minutes to fully drain you should be alright :thumbup1:
