I bought the CD version of the Genuine Honda manual for my '08 from Wingstuff. They sell both CD ROM and printed versions. Both have their advantages so it's your choice - paper or plastic. IMHO, I'd stick with the factory manuals as opposed to the Clymer, etc.
I bought the paper OEM manual from Wingstuff. I prefer it to a CD. Nice to be able to open the manual to the page(s) you need and wrench away. I thought about the CD, but I know my laptop would end up with grease/grime all over it.
I ended up with the paper version, but thought I ordered the cd from WingStuff. This puppy is huge! I had to build a cabinet just to hold it. There is more info in it than I'm sure I will ever be adept enough to use; or have the time , place and tools to do it.
I had a CD for my 98 GL1500. You could print out the pages you needed to work on the bike. I don't have a service manual for my GL1800. I guess I've learned what Dirty Harry said all along, "a man's got to know his limitations". I know mine. I'm better with a credit card than a wrench.
I bought the original paper manual from wingstuff and boy its a huge sucker i think i paid just as much for the shipping as the manual due to weight. It's a beauty it has everything you need. The only thing i dont like is thats its too heavy o read in bed
