Barn find CB400/4 For sale

Good morning
I have a Barn Find 1974 CB400F/4 Supersport that I am looking to sell I was planning on rebuilding it but due to health reasons I am not able to do that so have decided to sell it.
Its in quite a state & will require a lot of work to return it to road worthy condition.
It has only 11,400 miles on the clock & I have been informed the the engine was started & ran last year.
It was imported from the USA in 1990.
Unfortunately for some reason I can't upload any pictures so if you can let me have a email address I send them.
Thanks
Rob.

Hi Rob.
You need five posts before you can post photos and I see you now have 5 posts so should now be able to upload what you need to.
Good luck.

Big question
Is it UK registered with a V5?

That's going to need a lot of work! Are the missing parts available? 😲

That looks like it was found in the local pond.

I think that one is for the brave to take on. It's going to be expensive.

Getting the parts necessary to restore it shouldn't be a problem - DSS likely has all of them.
But it would be quite an expensive project AND probably require a lot of time to do the restoration. I've found that such projects always take far longer (and much more cash) than originally anticipated!
With the bike in that condition you might be better off parting it out. OTOH, if priced low enough it might sell to someone who REALLY wants a 400F to restore, has deep pockets/plenty of time and really enjoys the satisfaction of doing the work! As previously mentioned it needs to have a UK registration. Regardless of price it would be a very tough sell if it doesn't. Absent the V5 I would part it out. Somebody will buy the parts!

In all honesty Rob I would expect a full nut & bolt restoration of that bike to cost north of £8k and that's assuming you strip the bike including the engine and reassemble it yourself (and do a lot of the other work such as polishing, cleaning and running around getting parts). It would be 100% worth trying to save the original tinware even if badly pitted, any pits can be filled with brass before re-plating.

It doesn’t have to be a full nut and bolt restoration though. When I bought my 500 in 1995 it was a pile of bits. Many of the parts I bought to repair it were second hand, and I just wanted to make it mechanically sound and be something cheap and fun to ride. It is rusty, scruffy but runs really well and gives great enjoyment , people are always complementing me about it. For me it would depend on what the engine is like, everything else could be make to work without spending a fortune.
I just got my 350k going after 30 years standing. All it cost was a gasket set, two tyres, inner tubes and rim tapes, plus rear brake shoes. Everything else was simply cleaned and tidied. All depends on what you want.
