Well, either everyone else knows something I don't or I may have got a bargain!
Won with a sole bid of £105
Here's hoping

That's the one - there seem to be a few appearing but I wasn't sure which engines were compatible.
Seems cheap and reasonably local so might have a stab

Been keeping an eye on ebay for a replacement engine for my 1975 400f and wondered what compatibility is with later engines - i.e. There's a 1978 one at the moment but i wasn't sure if this would fit straight in etc.
Advice very welcome please

Got the engine fully stripped and am deciding whether to bin or rebuild as the general condition isn't very good inside.
Cosmetically all is OK on the outside and joint faces, fixings etc. are all OK which is the good bit.
Pistons / bores are badly worn - clocks show 56k miles so maybe original and just run into the ground by previous owner(s) - I've had great advice and help from one forum member already so think this can be solved quite easily / economically with new liners and pistons.
Camchain guides all look quite worn but I guess are easy replacement.
I think the deciding factor is whether the non-easy replacement bits are serviceable so I'm after a bit of advice on the crankshaft as start.
The crank and bearing areas all look visually OK but I think the big-end side clearance may be over limit - from the old Haynes manual I've got it looks like this is simply a feeler gauge measurement and if so mine is quite a bit looser than it says it should be. Is this the best quick check on condition or would the engine be OK even if there is some excessive wear here?
I'm guessing the crank will be the deciding factor on the fate of the old girl so any advice etc. welcome on how to assess this will really help the decision.

Assessing the engine that came with my latest bargain basket case and would really appreciate advice etc. now it's stripped.
Clocks show 36k miles and bike generally looks to have had a pretty hard life.
Bought it partially stripped but dry stored.
Bores are worn and pistons all had broken top rings so I guess rebore is needed - any idea on cost and where to get it done?
Bottom end seems OK at first look - are there known problems I should look for / things to check?
I guess key question is whether it's sane to refurbish the old engine or look out for a running one instead - any opinion?

Thanks all - good to hear no one questioning my sanity so far!
Off for a couple of days to Wales then back to start looking at the 400 motor so expect a few posts full of questions.

Hi all - just joined the forum after searching the web for info on the 400/4.
Bought a basket case - I really should know better but it came with another bike and was of course too good a deal to miss!!
In the process of assessing condition and if / how to go about restoring the poor old girl so will be in need of sound advice (counselling?) and this forum looks like the place to be.
