A lot of effort by many people has gone into creating the pdf's on the site to assist 650 owners.
Unfortunately there has been a lot of "Hot Linking" of the pdf's which has been using a large volume of bandwidth.
It seems much of the Hot Linking has been from automated systems and pdf viewing sites some of whom charhe to view pdfs rather than people legitimately posting links to files on forum pages or saving links in browsers so changes have been made to limit direct linking to the pdf's to the legitimate forums discussing motorcycling or the 650 models
If you are unable to link to a pdf from your forum let me know and I will consider allowing direct link access.
If you are unable to download a pdf some modern browser default settings prevent pdf download, Google chrome in particular which has generated multiple enquiries via the contact form & has been resolved by changing browser pdf settings, I would not be surprised if Microsoft Edge also has similar issues.
You can use the "Back Arrow" on your browser to return to the page the pdf is on or use the section menu on the left
You can also use the Contact Form to let me know and I will look into it, remember to include the link to the pdf.
When using the contact form if you do not see a response in your inbox please check your spam folder, too often the first emails from unknown email addresses will go to SPAM or Junk folders which can be annoying
