Just for fun, cause I am crazy like that, I did a quick compare with the numbers on kawguys site with the numbers on zedder. They over all are rather close, there are some year and models that do not match perfectly but are not than far off. Not claiming the info on zedder is correct by any means. It is a list to be made useful as one can as is the new list from kawguy.

Yep, speaking of Zedder, I purchased the downloadable shop manual from them online. Was supposed to get an email to where to download it and they never responded. Anyone else have that problem?

I have never attempted to purchase anything from zedder so can not speak to your issue. Will say make sure you look in whatever is called spam folder or like in your email.  All I have ever done regarding the data on the zedder site is make use of the lists they offer for some KZ machines. Note they do not provide any info on (K)Z650 numbers. and the data stops in the early to mid 80s at best. Do I think it is 100% correct, NO. It is another list to make use of nothing more.

What year or model service manual are you seeking, that has created the issue with them? There are several listed on this site and on others that are free if you look hard enough.

Yes I found it here in the article area...73-75 Z1. Thank you
