Oil Smoke on start up

[rmarkr]

I see we have an oilsmoke thread, but it's closed.
I left my bike on the center stand for about a month after a fairly cold and wet weekend ride. It would not start after 3 or 4 attempts - just a cough or two. Charged the battery back up and tried the next day. Same deal. I keep my thumb on the starter with the throttle open until it finally spluttered into life, belching a horrendous cloud of white smoke.. and it kept coming, until after a good few minutes. Then it ran like nothing had happened. What could this be?
Its a 91 K100RS with 45k on the clock. I gave it a compression test, before this incident, and all looked good. I have noticed a small amount of oil consumption while riding - maybe 1/2 a cup per 1000 miles. (it never used oil before). It has 20-50 synthetic oil in the sump - fairly fresh.
Is there anyway that the air intake is sucking in oil through the crankcase ventilation system?

White Smoke, is likely fuel being vaporized........not OIL

Are you using any fuel additive like stabil??

Every time you cranked ,, fuel was placed in the combustion chamber and out the exhaust, try a battery tender and heated garage....

I have written this on earlier threads - but since it fits, I repeat it here.

If a K75, K100, K1100, or classic K1200 motor doesn't start in the first 5 seconds, and a couple of more tries produces the same results, you might as well stop, remove the spark plugs, dry them off or replace them, and then start the bike.

This is especially true if it is cold - below 40 degrees - or if the battery is low.

The ignition module cuts out on low voltage before the LJetronic cuts off the injectors due to low voltage. Thus, it keeps squirting without any spark at the plugs. Even if you then charge the battery - more times than not you will just run the battery down again before the wet plugs will fire enough to make the engine run.

And as a related aside - cranking a classic K bike with a low battery often results in a stuck starter relay - so the starter just keeps cranking, button released, key off, it doesn't care. Then you scramble around to get the battery disconnected. The main ground on the left side of the transmission is quickest if you have the allen wrench handy.
