SpencerPJ - The intake horns go just under the fork shield. I've attached a photo of mine when I had it apart last. The horns are loose, since I had the cover off for the filter, but you can see where they go.

By the way, tax4free...if you've had any codes for the cam sensor or hard to start (spins over but does not fire, whether a code present or not), filter changes are a great time to change that camshaft position sensor, which is somewhat prone to failure on the GL1800s. I had a few of those instances, and replaced mine proactively the last time I did a filter change. Good luck!
