Yes, I have a riverside. What I did on it at first was a cheap quick easy way which I would not recommend doing. My motor kit came with extra motor mounts, so I turned the extra one the oppisite way to make it longer then used the bracket that is supposed to be used to drill tha frame. Now I just ordered a Motor mount from Creative eng. That is by far the way to go, as your motor will be sitting perfect, straight. Plus it will be easy to take the motor off quick if needed.
