Mark II engine I.D. ?? with 28mm Pumpers

Going to look at an ugly, sitting for 7 yrs. Smog head 79-80 KZ1000 engine. This person is throwing it in for the sale of VM 28mm pumper carbs. The carbs that were stock on the Mark II's and the 80 Z1R. and (??). But He has a cleaned rebuilt set of the 28mm accelerator pump carbs. He sent to Wired George the carb guy. Said he paid $400 for the carb work 3-4 yrs. ago? Whatever? I am going to look at this stuff this week. I know some late 1978 1000's still had a small pin crank. But had the new style dyno and stator cover and smog head. I am hoping it is a Mark II with big pin crank. I am going to pop off the smog cover and count the cam sprocket teeth, if my old eyes can manage that.

Another question? Are 28mm OEM pumpers worth the money?? I would assume only for a Mark II or 80 Z1R restoration. I always thought the pumper carbs were ugly for other bikes. it also has another set of the same carbs, not rebuilt?? I'll see them Monday. 2 sets. 1 clean and no idea on other ??
He wants $400 for the 2 sets of carbs? And the engine plus all his greasy, rusted crap in a box . It's local, only 30 minutes away from me. It is a chain drive engine, could be LTD or MarkII? I'll get to see the engine # and search zedder, when I get there.
Just looking for opinions?
Thanks in advance.

Never seen a late mk2 style engine with a small pin crank.
They all had the big pin 16t one and the alt taper is bigger for the dished rotor.
There was an 1000A model that had the heavier 1000 crank but still had the 8mm alt bolt and woodruff key so maybe that is what you are thinking of.
With that alt cover it has to be a MK2 type engine with big pin 16t crank.
Could be a Z1r-D2, mk2 or B/LTD.
Engine number will tell.
And those 28 pumpers the best of all the carbs. so are worth money.
$400 for the lot is a gift.

Is there a extra rib by the clutch?


.

Thanks! N R, I forgot about that extra ribbing on the case. I will see Monday (4-16) evening.
Plus the KZTOOA # will tell. Either way, If it turns over nice? I'm gonna pull the valve cover too. I'm bringing it home.

Smokin score Marty. I will drop by next Tuesday when I go to Buffalo and take those carbs off your hands! Just kidding, but I have seen some of those carbs in clean condition go for what you got everything for! Nice grab.

We'll, Wednesday is the day. Guy has been busy. Me and my son are going to check stuff out in afternoon. The engine looks like a boat anchor! Rolled in salt?
I'm gonna pull cam cover to count the cam sprocket teeth. cases are silver, so it must have been an LTD?
I'll let you know tomorrow with some pics. There is a 2nd set of carbs there too. Hope the stuff is good!

Looked at engine. Not Mark II. # 754611. Small pin crank. 30 teeth cam sprockets. 3 big chunks out of the smog head. The 2nd set of pumpers were the crap 26mm. The 28’s were not professionally done.
I said I did not even want to make offer, it would have been $100. It had points still. The only thing it had good, was that it turned over! Plus it was oil clean inside the cam cover. Oh well had to try. Spent an hour in a cold garage. It was only 33 degrees out!

At $400. over hear in the UK there would have been a line a mile long to get that little lot.

So what engine is it ?
Never seen a 15t cranked engine with that finned mk2 alt cover here in the uk and i've seen and had them all and thought i almost knew it all too .
Can't even cobble together a franken motor like that because the alternator is totally different and the 15t crank taper wont accept the larger tapered dished rotor.

Most of the 79/80 LTD 1000'S I tore apart had 15T cranks in them but not all of them.

So did these originate from a US plant to use up surplus 15t cranks and is it just a small amount of them and just LTD's ?
Was there any model designation or engine number range to distinguish what crank etc was fitted or was it russian roulette as to what you got ?
Over here in the UK all stock square cam cover motors ( also fitted to ST , LTD and Z1R D2 ) came with 16t cranks and finned alt and ign covers.
They never had a 15t crank here.
The big selling point for the MK2 motor was the revised styling and the stronger crank and gearbox,
Obviously it's only the diameter of the taper that prevented the later dished rotor to fit the 15t crank the so I presume they simply just cut the small taper in the dished rotor.

Yes, it was small pin. I took off cam cover and counted the teeth! 30. This happened to me about 10 yrs. ago. Guy said MKII it was not. Got burned.

Poor Guy has health issues, he was selling everything he has. Felt bad for him. These were his phone pictures. I did not want to take any pics in a strangers garage with my phone. But You get the gist! looking at this one.
