have a 07 road king when i first start it when its cold the right exhaust pipe smokes for a while then it stops but the left side you dont see anything.only out of the right anybody's bike do that

 

My '04 RK did it, and my '08 Ultra does it. It only does it for a short while, and the smoke is white in color.

 

The first thing I'm wondering, is it really smoke or just cold exhaust vapors. It's going to be normal to see more from the right side since that is where 90% of your exhaust is coming out of.

 

left side is almost a dummy as the bulk of the exhaust comes out the right (unless you have true duals).

 

Probably is the same phenomenom when you star your car in the morning, and it sometimes drop even water. When i was my ride, some water allways enter the mufflers, when I start it to warm and finish drying it, it does the same for a while.
