I don’t like Rotax’s documentation. It’s extremely detailed to the point of nearly being unreadable. I also haven’t found anything that remotely resembles an index, so it’s impossible for me to navigate the plethora of pages to find the minutia of importance. Case in point. I recall reading that after 1st start, you must remove the valve covers and verify that the lifters don’t move with 15 # of pressure when the valves are both closed at TDC for each cylinder. This blog entry is to document that I have performed that procedure, but I can’t find the document to cite it properly. I’ll amend this posting when I find that document.
