Folks,
I just purchased a Kitfox IV with a 80HP Rotax. Looks like the serial number is B780? Does that sound right? I thought they all had 7 digit numbers. This engine was new somewhere around 1992, I think.
I want to learn all I can about it. Any ADs, recommended TBOs, maintenance, etc.
Is that a valid serial number?
Where can I find information on it, how to care and feed it properly?

Thank you!
Bob
