Rotax 582 conversion install on Challenger 2 ultralight

I upgraded my challenger 2 from a Rotax 503 air cooled engine to the higher HP liquid cooled Rotax 582. I go over all the details in this video of the install including small tips and torque specs. This is just my experience so please always do your own homework if doing something similar:) I've had a lot of help from John Baker (rotacrepair.ca) Bill Bryan(Toronto aerosport , stouffville airport) Greg Klemp(sheer technologies), and Mike Harrison(quad city challenger). Thank you to all you guys!
