KZ750 Canadain Model

Hey everyone, I been looking on google and i can't find what i'm looking for, So my question is, How many KZ750 LTD's were made in 1981 that are the canadain model, or KZ750 LTD's in general. So who ever would know this or link me to a history type page it would be a load of help.

I sometimes find useful info at www.cyclechaos.com/wiki/Kawasaki_KZ750H

I'm not sure how accurate it is...but the 1981 750 frame numbers start at KZ750H-013501 and the 1982's (another good year ) start at KZ750H-031601, so that would lead me to believe that 18,100 '81's were made.
