Any Stock Kawi 34T - 36T Rear Sprockets in 530?

My '79 750 twin came with a 38T rear sprocket and 530 chain. I changed it to 32 which is better for me, which was an aluminum aftermarket sprocket. I was looking at getting new sprockets and chain, but want to stay with a higher drive ratio. Are there any stock kawi rears sprockets that would fit in the tooth range of 34 - 36T?

Stock sprockets are available cheap (and in steel) but customs are aluminum and cost about $75 each.

I'd like to run either about 16 - 34 ratio or 17 - 36, so any rear from about 34 - 36 would be OK.

I would call z1 and talk with them, I am sure they would be able to tell you what is aval and what will fit.
