Just in case you're new here and haven't heard about them, I have a complete set of 20 DVD's that cover just about any and all maintenance you would ever need to do to a GL1800. There is close to 40 hours of video on them, and I cover everything from total fork rebuilds, to valve adjustments.
These videos were a labor of love for me, and I never originally intended to make money off them. My original motivation for creating them was to educate and empower owners to have the confidence to work on their own bike. They cover every model year GL1800 made, and I have updated them three times over the course of the years to keep up with the changes to the bike. You won't find a more complete set of maintenance videos for this bike anywhere, period.
I just received Angel ride's DVD Maintenance videos. I find them very detailed and extremly easy to follow. I run a motorcycle ministry and we help folks work on their own bikes. Working on a goldwing is very complicated without some sort of guide besides the Service manual. Thanks Fred for such a well made product!
