Advice replacement engine?!

My zxr400 failed compression in cylinder 1.. Possible that a valve has dropped...damaging piston head, head cylinder etc..

I've come across this engine in a motorcycle shop they want £250

They said:
It's possibly 1990-95 model
Unknown mileage
Came into workshop 99-00 after an accident causing the generator case to crack.


It's so clean on the outside! Compared to my corroded walls!

However as you can see it's been sat for a long time! Risk of dry seizure etc..He said he would do a compression test but can't run it as it doesn't have the generator. And if it didn't run in my bike then he would refund me..

It's hardly been used ..

Pictured is mounting welds.. Not sure if that's from the same accident ..?

Also the exhaust outlets have not been covered!

What do you think??. Would you buy it?
Too risky?

Here is another to compare .. https://www.ebay.co.uk/ulk/itm/272191776502

Maybe I'm being dumb but I'm not so sure that's a Zxr 400 engine.

Different rocker cover, different clutch cover, different thermostat cover.

its a sleeved down zzr600, and not a detuned zxr400 so it wont work without many, many mods.

Thanks! What an absolute sausage I am!
You know the seller at the shop kept saying zzr and I asked if it was zzr or zxr and he said zxr .. Saved me £250!!

Next question do you reckon I should fix the valve problem or break it for parts Image

Have you lifted the head on your engine? Defiantly sure it's a valve?

Not yet, it's what someone charged me £30 to do a compression & tell me it's suspected as there's no compression from cylinder 1!

He said he would have a look for £30.. We misunderstood each other clearly.

So I've took it back, got it back today, I'm going to lift it myself and look

Vid attached, it's been slightly rattling but then something literally clunked at lights and it sounded like below
When I got it to the garage it was quieter ..

Does the tapping get faster as you Rev the bike or stay the same?
