1.) Links to lots of manuals, some are defunct, but still a lot of good information: Dan's Motorcycle "Shop Manuals"

2.) Lots of Honda specific stuff: http://ridecbr.com/2012/04/16/free-h...rvice-manuals/

3.) another good source for a lot of different makes and models. They even have some hard to find/vintage stuff on here: Motorcycle service manuals for download, free!

4.) this one has been floating around the forum for years, but Ill add it anyway, lots of honda sportbike manuals from the 90's and 00's: Stephy G's CBR F4i Page (skip the intro and look to the bottom of the page)

I am a professional Bike tech and I run a small shop in the Omaha, NE and I refuse to work without a manual in all but the most basic jobs to ensure I have proper torques, tightening sequences, etc. If I cant find it on the links that I put there, google almost never lets me down. in over 5 years, I can count the amount of times on one hand that I have had to pay for a hard copy or download of a service manual and I see bikes of all years, makes and models.
