Fred Harmon has made maintenance CD's for the GL1800, and has received many favourable comments. Does anybody know if the CD's include specific information for Canadian made bikes?
The majority of changes that have occurred to the GL1800 over the years have been electrical in nature. In 06 they increased the radiator and fan sizes a bit and put on a bigger alternator and GPS and heated seats and grips. In 09 they added the tire pressure system and upgraded the GPS and added XM.Thanks for the above responses. I should have mentioned that my bike is an '07 Airbag - which is the 1st year for the airbag model. I do have the 2006-2008 Service Manual and there are many specific references to Model IIICM, which is the designation for the Canadian GL1800. For example, on p. 178 a diagram shows the Cable & Harness Routing for VIIIA (U.S.) and IIICM models only. Many other diagrams have a sub-heading "Except VIIIA and IIICM". I may have to contact Fred Harmon to ask if his CD's include the airbag.
