Hi Everyone,
As far as I know the Z1000 H1 engine no.s should start : KZT00HE-......
I believe that this type of fuel injection engine was fitted to an America only model known as the KZ10001G / Z1 Classic - with engine no.s that start KZT00GE-......
My Question is were any Z1000H's likely to be fitted with an engine no. starting KZT00GE-...... from the factory?

Simple answer is yes
My German H had a G engine number

Gents, please forgive me for asking but do those "G" motors you have in your "H's" have a cylinder head with SMOG PORTS ? (Exhaust Gas Recirculation ports) My accumulated understanding from experience is that "H" motors do not have Smog Ports and the H was not intended for sale in the US. The "G" was intended for the US has a full EGR system with the ports in the head.

I have parted a few G engines with no smog and dont think i have seen a G bike with smog fitted. Maybe because the fuel injection negated the need for it

Thanks for the replies and information gents !
Makes me ask myself a few questions.....
All the H heads I ever had through my hands were similar to none US Mk2 / ST heads where the casting is there for the smog ports to go through but just left solid i.e. no ports. The US bikes had the ports and reed valves on the rocker box top. The G/Classics I have any experience with have actually just been cylinder heads and HAVE SMOG PORTS ! and I assumed they must all be the same being a US market bike.
