    That's like telling the guy who has a constant light loss of air in a tire not to worry.....

    From the video, it looks more like unburnt fuel. The way it started, sounded to me like it labored a bit. If you have an injector leaking down at the check valve, fuel pressure may leak down into the throttle body overnight. You mentioned both plugs were black, a definite sign of excessive fuel. If it was oil, they should be fluffy with black carbon and if yours have a dusty coating of black, that's fuel.
    The way it labored on start up can sure be a sign of a very rich start mixture, which could be caused by restricted air intake, a dirty filter comes to mind and would more readily explain two fouled plugs against my thought of leaking down injectors. Either should be easy to prove with a look at how much vacuum each cylinder has. I just can't see two injectors crapping out at the same time, unless the problem was gradual. Either way, diluted crankcase oil will only tell you have a problem. Do the blotter test to see.

    I think its oil.

    Fuel burns black.
    Oil smoke is blue.

    Smell it. Oil or gas?

    Black spark plugs right after start up is not that big of a deal. The engine runs much richer for cold start.

    I think it should be ridden for a while before panic sets in, its only light smoke and its only on start up.

    Check the oil frequently (I seem to check mine too much) and ride the bike.

    When I took my RT apart after 130,000 miles, the cylinders looked good, the ring ends were all lined up on top. I have been told on the internet the rings tend to rotate as the engine runs and it could have been dumb luck or just the way it was.

    IF your rings do rotate a little as the engine runs they could be lined up on the bottom.
    IF this is true then in time they will rotate to some where else.

    I have no idea if this is true.

    BUT I think you should ride the bike and give it a chance.

    More ifs.

    IF you did get a good dose of oil in the cylinder head, it found its way into the cat and takes a while to burn off.

    Both of my BMW bikes have on occasion done this. It would leave a huge cloud of smoke in the morning or after a long hot hard run then parked on the side stand. To clear it out of the cat, the bike needs to be run hard again or it may continue to smoke until its burned out.

    I had the valve guides replaced and a complete valve job on my oil head at 130,000 miles and it did not need it.

    Engine wear does not take place all at once.

    I had about 3 minutes of white smoke once. Never again. Wonder if cat converter turns oil smoke white?

    Maybe the random occurrence of having the ring gaps aligned on the bottom will still allow oil past while on the center stand.

    I'd ride it, not because I'm lazy, because I think it will cure it.

    New Oil = No Smoke

    Again, thanks for all the reply's. (Once again I have to say it...the helpfulness and camaraderie of this group is second to none!)

    Not sure why, but last night I decided to go ahead and do another oil change. Bike was plenty hot (5 bars), and I just did the oil, no filter. Did a little ride last night, then had it on the center stand all night. This morning... you guessed it... NO SMOKE!

    So what does that mean... there were just some bad bavarian gremlins that needed to get flushed out?

    Bottom line.. I will ride it... in fact, ride the snot out of it! This weekend is Soldiers Grove, and rain, thunder, or smoke, I'll be there.

    Thanks again for all of the insight.

    One other question while we're here... the bike is a 2000 with 48k... and what point should I expect the failure of the mentioned potential issues? (valve seals, head gasket, etc.)

    Never expect it! Having a expiration date will just cause STRESS!! Stress does not go with motocycles!

    if you keep up on your maintenance, you might consider having to do engine upper end around, oh, maybe 250- 300K. maybe. engine lower end, umm, ya know, I can't recall really hearing about somebody having to go into the lower end of these things, barring an owner doing something dumb.
    cam chain rails maybe 150-200K?
    seriously, these motors are quite solid.

    Paul, Anton- what you got to say on oilhead longevity? (see, I know Paul has seen upwards of 360K on Voni's BigRed, motor untouched)

    Like folks have been saying- stop worrying, and just ride the damn thing.

    Mine is just a baby, 00 RT with 32k on the clock and I think all the moving parts just got comfortable with each other at around 28k. My point is just after I bought it 5/11 I ran into a guy here in AZ riding a 99 RT, same color with 172k on it, I asked him about the reliability of his. He said he has been all over the country, never had a problem, he does his maintenance at BMW but didn't hold to the factory schedule, changed the oil when he thought about it and used whatever oil was on sale at Wallyworld. He did keep accurate records though, said he's put on 17 sets of tires to date.

    I have put 20k on mine since I've owned it, 3k on a round trip to Texas last month, favorite bike to date.

    Cheers

    Update

    So far... still no smoke!
    I did the oil change last week as I mentioned, went to the soldiers grove rally where it was always parked on the side stand, and never any smoke. (Had a great weekend with over 700 miles of hard twisties! )

    So I'm still convinced....Bavarian Gremlins!
