    Fellow 690 owners,
    It's been cold here in Colorado. The local temps been around 10-20F avg for the last couple weeks. When I start my 690R the oil warning lamp will stay lit up for several minutes at idle, and as the engine temp rises the light goes out.
    The oil has about 2,000 miles on it and it is filled to the correct level. My thoughts are that things are OK,,, just the viscosity of the oil may be a bit heavy for this temperature range. I am running a full synthetic 10/50.

    Anyone have any thoughts or advice?

    Growing up in MN I've run bikes in very cold weather. You are correct in the viscosity being too thick. If you plan to regularly run your engine in those tens, please change the oil out for something around 5W30. Your engine will thank you.

    (Just remember to change it back in the spring!)

    I'm going to talk with the shop when they re-open this wednesday just to be sure they agree with what you and I think is going on.

    I need to change filters and oil anyway,, so for now I'll put in a lower viscosity then when it gets back to warmer temps I'll just go back to the 10-50.

    What threw me for a bit of concern was the fact of it being full synthetic,,, I always thought a synthetic would not be effected by cold temps as much as a petroleum based oil.

    When I read the owners manual it doesn't specify using anything lighter than 10-50
