GL1500 grey smoke at start up

You do an oil change recently?

Grey smoke is fuel, blue is oil. Check the plugs. They should all have a nice grey/white residue on them. Sounds like you have a slight fuel leak into one cylinder. When was the last time you checked your plugs?

I changed the plugs about 4 weeks ago.

I am sure hoping it is fuel related. I did run some seafoam through just this past week to help clean up a slight burbling when cruising in OD (which it did..)

It runs great now but I am fearing that I have opened another can of worms on this..

Was thinking high oil level despite the color of the smoke.

Me too, and it was a bit high so i drained it down. so it is between the two marks

Mine did the same thing after about a week or more of below freezing when I started it up.

That is normal on the 1500 Gold Wing. When left on the side stand a small amount of oil will seep past the ring and smoke a little on start up. Nothing to worry about

Park on the center stand whenever you can

:claps: -- WINNER --

In all probability there is probably not an issue. If moisture is mixed with any type of oil substance you can get gray smoke. In the cool months there will be more condensation in the exhaust etc. There is probably a certain amount of carbon/sludge in the muffler as well. Especially if the bike uses a little oil. In the cooler weather the extra condensation sits with the carbon and mixes. When you start the bike it will burn the water and a certain amount of carbon with it. That is probably your gray smoke.
