The machine started right up and runs good. It sounds like my Outlander. The one thing I need to do it try to find a spark arrestor for it. If anyone has and ideas, let me know. The outlet of the muffler is 1.5". I am hoping I can find something to weld or clamp on. From looking at the engine, there is no doubt this motor is a Can-am clone. There are a few things they left off but for the most part it is exactly the same. The nice thing about this one is that it uses a closed loop efi system with O2 sensors and the original does not. This one should run a little better at altitude. I am really hoping I can find a cage extension that will fit this or I am not sure what I will do.
