Great, we can have 100 sport races as there are a few in town.
Best place for OPIs on older bikes is:
CycleWorks
5688 - 75 St.
780.440.3200

Easiest to get there when south bound on 75 St.
First you need to bring your import documents to a registry office and they will provide you with the OPI request forms. Take the bikes and the forms to CycleWorks. They'll do the inspection and, provided the bikes pass, give you another form which will let the registry office issue registrations. Of course you will need to arrange insurance beforehand as well.
Now the bad news, Your 100 sport is going to need signals, horn, reflectors and any other missing equipment before it will pass. The other bikes may or may not need the same depending on their year of manufacture. The OPI is a straight pass/fail with no refunds and limited opportunity to sort things out. So make sure the bike are right before getting the OPI request forms as the forms are time limited with no refund.
