Have found a small leak of a yellowish fluid at the base of the intake riser where it attaches to the head at # 6 cylinders spark plug area. The Kuryakyn spark plug covers are NOT on yet due to the fact that I am waiting on new spark plus to replace the old ones. I have a washer under each  Kury bolt to take up the space due to its extra length. I guess they are torqued to the proper torque of 6.5 ft lb. I took her out for a ride today and noticed the fluid when I got back, and it was not there before the ride. Ant thoughts.

they are in a recess underneath the bottom side of each intake tube.  You can take one with you to your local auto parts store and get  replacement.

Is it possible to unbolt the bottom of the riser and replace the O ring without  taking everything apart?

That's what it is!  A leak at the bottom. That's condensed intake fuel mixture finding it's way out.

Take the two small bolts out, loosen the band on the bottom of the rubber tube and pull/twist it out.  Simple job.

Important note: have shop towel or rag to place into intake to prevent an "oh sh!!" if something falls into the manifold.

Docx try to find vitron rubber o rings. They are better than the original.
They are Dash 123 O-rings

The metric size of the o-ring is (28MM X 34MM X 3MM)

Advanced Auto's Parts carries it by the part (#64628.1)
I purchased a 50 pack of vitron 123 orings a Grainger for like 8 bucks. Lots cheaper than OEM and they last longer.

Doc X  Yes replacement of those o-rings is simple.......but, I have one question for you.  You said you are waiting on spark plugs.......Why are you waiting? 

If they were out of stock at one parts place just go to another........if you are waiting on the Honda dealer, what you are really waiting for is a royal screw job.  The exact same plug is 1/4 the price at your local car parts place
