The Honda manual can be a bit hard to read and leaves out some basic stuff but the info in it is the best. Clymer manual has some stuff downright wrong. Particularly in the wiring.But it is pretty good. I've not seen a haynes manual on wings yet so I can't say good or bad there.
My opinion only. Clymer cannot be trusted and is fit for lighting the fire with only!
Use the Honda manual first, backed up with the Haynes one, and you will cover most things. Anything you are unsure of..ASK! That's what this and other Wing forums are for!
I've the Clymer (GL 10/11), Haynes (10, 11 and 12) and the '78-only Honda DIY Maintenance Guide there, along with a bunch of single-carb stuff that I think is important. Have the Factory 1000 manual on the old D/L page and haven't moved it yet.
You can start here. I have one of each including the '75-'79 shop manual in a Honda binder. Keep searching and you'll find a good deal. I paid $35 for my shop manual but, as stated above, you can download them from various sites.
