Hey Steve, I have my carbs off the engine to some, they really needed it!!! But for the life of me can't find cc stamp by the intakes. Do you happen to have an example? Thank you sir!

No on the front under the # 4 exhaust next to the case.

A J model cylinder block is pictured, which is visually similar to Z1 and KZ900 and KZ1000 cylinder blocks.

Good Fortune!

KZT00A-510284 probably is the "full" VIN.

Per www.zedder.com :
Year & Model '78 KZ1000-A2
(USA MFR)
KZTOOA507027 - 515034
Engine No. Range KZTOOAE042501 - 058140
Engine No. Location RH top crankcase, below carburetor
Cylinder Mark 1.015L
Cylinder Mark Location Front RH corner

KZT00A-510284 falls within the USA manufactured '78 KZ1000-A2 models which have VIN's ranging from KZTOOA507027 - 515034

Good Fortune!

For comparison, here's the 1980 LTD info from zedder:

Year & Model '80 KZ1000-B4:LTD
Frame No. Range KZTOOB-523544 - 535555
Engine No. Range KZTOOAE092601 - 092900 AND KZTOOAE093001 - 110764
Engine No. Location RH top crankcase, below carburetor
Cylinder Mark 1.015L
Cylinder Mark Location Front RH corner

Good Fortune!

Would seem to be a '78 KZ1000-A2 chassis with an engine from some other model (Z1-KZ900) to be more precisely determined by the complete ENGINE serial number.

But, regardless of the ENGINE serial number, it's also possible that a KZ1000 cylinder block from a later model was installed onto whatever the 903cc engine started out as.

For example -- Z1 engine with KZ1000 cylinder block in a 1978 KZ1000 chassis.

Good Fortune!

It does indeed have a 903 on it, thank yall for helping me confirm that!

That narrows it down to a '78 KZ1000-A2 chassis with an engine from some other model (Z1-KZ900) to be more precisely determined by the complete ENGINE serial number.

Now, if we can just convince swest and others with a sense of humor that the engine's not from a Porsche Spyder. :lol:

Good Fortune!

Welcome and Thank you for your service

Now looking at your last picture Is that a crack in the weld on your frame where the engine mount plate boss is ??? :pinch:

Is that a big fat crack in the motor mount weld at the frame?

Dang it, Dave. You are just too fast. :woohoo:
