identify fork year

I had a KZ900 engine sitting here and I came across a titled 1980 KZ1000 frame so it will be mainly KZstuff. I have the mag wheels and plan on using the KZ front end with dual discs. So it will loosely be a 1980 KZ1000 mutt. I was going to use a 4 into one but Delkivic was offering their 4 into 4 for $1099 so im going with those. Just didn't want to deal with the noise from the 4 into 1. I was wondering what the Dlekivic pipes look like anyway now I will find out.

Thanks for the offer but I net the KZ forks. As I mentioned I already have a set on the way. Probably will need new tubes for them, oh well
