welcome. I have brought many bikes across. It's not that bad. First get the bill of sale and the title. Find out when you are going to bring it across the border. Call up border services and talk to someone there and let them know you plan on importing said vehicle, and ask them where to find an import form, fill out and fax to them with all the other paper work. It will take about 3-4 days for them to approve. Pick it up, claim it, go in and pay the taxes, get inspected.
If you aren't ever planning to drive it on the road, just claim it as a parts vehicle and ignore all of the previous steps.
The safe word is HWhisky
