I finally got all the parts to do my first oil change. The change was real easy. Why would someone pay $150 to do this? The only problem I had was jacking up the trike. I ran the front wheel up a ramp and then I jacked up each side and put a stand under the rear wheels. Not the best idea, but it worked. By the way I used Mobil 10/40 4T racing oil. Now I heard the it would make the transmission quieter. It did seem quieter, but am I looking for it? Like the old saying "If your looking for it, you'll find it"
