Coming out of retirement CB750K 1980

[ozengines]

I am looking at picking up a CB750K 1980 but need to ask some advice. I have been in motorcycles for 38 years and had a few years off, now keen to go again.
This is the bike in the pictures, barn fresh.
Needs tyres, blinkers, fork oil seals, tail light lens, front master cylinder, dump the front fairing etc. at a very quick glance. It has both side covers.
I looked at the oil and it is very thick, which means to me that the engine may need a heart transplant (full strip down) probably using oil.
I have not come back to the guy with price, he mentioned around $2000, I am thinking $1000 tops. I will put plenty of questions to the owner when we meet again.
What do you guys think. I am in Australia.

$2000 is way to much for a non running(I assume it does not run) 750 IMO.Depending on how it was stored,you could be looking at major carb work(gummed up),gas tank cleaning ,etc.-
Does the engine even have compression?

This could take a lot of cash to fix it.

Now since your from down under,are these bikes rare/scarce there which may bring a higher price?

As a comparason,my son bought a running good condition '82K for $950.

I agree:  if non-running (pretty much a given), $1,000 AUS/US/Whatever, is way too much!  How much will it take, just in parts, to make it run again?  How much will it be worth (what can you get for it?), when it is fully restored?  Check the condition of the gas tank's interior:  look for rust, as these tanks are difficult to replace.  Coating the inside with a liner material, is a hit/miss affair:  some folks have great luck, others have a disaster, and wind up in worse shape than when they started.

No matter how it was stored, the gasoline will have turned to varnish, as all of the preservative chemicals are only good for 12 months, typically.  If he drained the tank, and the carbs, before storing the bike, it might run with just fresh gas and oil.

With the oil being very thick (could have thickened from sitting for 20+ years?), adding SeaFoam will help thin it, but it needs to be mixed thoroughly with the oil, to do its job.  Try adding SeaFoam to the crankcase, then let it sit for several days, if possible, to let it disperse within the crankcase oil.  After you change the oil and filter, add more SeaFoam, and run it through all gears, and check the oil's color:  it should turn black, indicating that the SeaFoam has dissolved carbon, varnish, and other crud, throughout the engine, and the transmission -- change the oil and filter again, to be rid of all of that junk.

Add SeaFoam to the gas tank, after you dump its contents, to dissolve the varnish inside of it, if any.  After you get the carbs torn down, and cleaned, adjusted, and tuned, add more SeaFoam to the gas tank.  This will help clean everything in the fuel system of any remaining varnish deposits.  Cheers!

Well guys. looks like your comments have turned me off this project. The CB750K is not that rare here, ot should I say not that collectable, but I am not in love with the twin cam engines. I really am after a K0, K1 or K2 which start here, if running, at around $6500 to $24,000 for a show bike.
I think I will wait and save my pennies.
Thanks for the replies.
