In order to get the RSS feeds for a repository, you first have to watch the repository you're interested in. After watching it, head over to https://github.com and you should see news items for all your repositories start flowing in, as and when they happen.
Now if you need to use an external RSS reader (or similar), you should find a News Feed link on the main GitHub page that will take you to an aggregated RSS feed of any and all interesting things happening in your watched repositories. This will include information like pull requests, new issues, wiki changes, and so on.
You can get feed+token URL automatically from GitHub using the following steps:
(1) Login to your GitHub account
(2) Go to the following page:
(3) Click on the News Feed button with feed-icon in the top right of the page.
(4) This will take you to a feed XML page. Copy the URL form your browser and paste where needed.
(5) Filter the feed to your needs. The feed itself appears to include Issues updates and other details from all of the repos connected to your account. In my case, I just used a standard text filter to grab just the feed elements with MyAcct/MyRepo1 in their title.
