    Help...milky substance in oil level sight glass!

    Well, I pulled my motorcycle out of winter storage to change the oil, and everything looked fine. I started it up after a whole winter of sitting in the garage, and after a few minutes I shut it down and looked at the sight glass and saw some whispy white material just above the oil...Yikes! Well, I looked at the radiator overflow bottle and everything is between the lines as it should be.

    I drained the oil (no milky oil...actually very clear and clean), I replaced the filter, refilled the oil with Rottella T6, and still some milky whisps in the sight glass....so I hoped on, and took it down the street for a 10 minute ride, temp rose to right level and remained there. When I got back, I let the bike sit the appropriate time, looked at the sight glass and everything looked fine, no more milky stuff. WHAT GIVES?

    Do I have to worry...what should I look for? Cheers, and thanks for any suggestions or comments. Brad in Duluth

    Maybe a very small amount of water from condensation?

    The new oil that had white whispy stuff floating on it... have you looked at it again now that it is drained to see if anything settled out of it or rose to the top? (My guess is no, but just worth a check.)

    Dump the 5-40 synthetic oil and refill it with some Mobil Delvac 1300 or Valvoline Premium blue 15-40. They will clean the engine out much better than the T6 IMHO.
    The Dino HDEO's suspend stuff better. .02

    Sounds like you put it away with used oil in it and changed it later when you took it back out? That's backwards if so. The used oil will have moisture in it that probably caused a little emulsification while sitting. It's better to put fresh oil in and then store
    the bike.

    I concur with the condesation and leaving used oil in for the winter.

    I'm thinking your clutch and brake fluid should probably be flushed too

    Oops....Yes, it was backwards. I have learned a valuable lesson. It was just me being lazy and riding to the very last minute (so that it was so cold that I didn't want to work on my bike in an unheated garage!). I really appreciate the feedback.

    I checked the sight glass this morning and everything looked fine after sitting for the night (no milky clouds of any kind). It must have been a small amount of moisture in the oil as noted above...thanks everyone for their comments and advise....the PEOPLE and the SITE absolutely ROCK!!!!

    Cheers, Brad

    Follow-up question: It is correct to wait until spring (pulling bike out of storage) before changing clutch and brake fluid? My understanding is they actually collect moisture during winter storage. So, it looks like one can't really do ALL the fluids at once in the Fall (or am I wrong again)

    ... and I'm thinking you should just ride the damn thing. Once engine temps reach about 190 degrees for a while the H2O will evaporate.
