If you disconnect the steering arm as Tommy mentions above, you can quickly confirm if it's a motor swivel issue or a cable issue. Though it's possible to have a motor side issue, they are pretty unusual. It's nearly always the cable creating the headaches, especially if the plastic coating is cracking due to sunlight exposure. The shaft on the left side of the motor should have a thin layer of grease on it. Without that it can be pretty draggy sliding through the tube that the motor tilts on.
In any case, the steering should turn with one finger. If it's not, it's a problem worth taking care of ASAP. It's not going to get any better by itself, and worse case, steering cables aren't THAT expensive!
