The 1st thing I noticed is the output is stated at 75PS on the '89 sheet, my '91 sheet puts it at 80PS @ 13,500 revs - not to be sniffed at !
Sorry, but I do not have the time to convert the Japanese into English - so if some kind sole wants to take up the challenge they are more than welcome. most can be cross referenced with the English version.
I also have hand written notes from a Kawasaki technician who worked with the Suzaka team and will ask the wife to translate them for your reference

The one thing we can't work out and I might need to mail him again is he said they used a 8:2 engine oil / kerosene (Paraffin) mix , we can't work out if that's what he stored the F3 cam's in or that's what they used
