Spare 400 engine conundrum ?

[McCabe-Thiele (Ted)]

When my 400 rebuild project is completed hopefully in the next few weeks (Phase 1) I will have the what to do next syndrome this summer.
Not sure if I have the energy for a new build this year plus sensible project starting prices  are getting harder to find.
Do I keep my spare engine in the garage as it is unrestored or do I dismantle it and rebuild it just in case?

What is easier to sell on - an assembled unrestored engine, one in bits, or a restored unit?

Saw this anyone here?

Rebuild and put it on display

Personally i always treat a "rebuilt" engine as a project to work on unless from a trusted trade source with some sort of guarantee so unless you are bored i reckon you would probably spend more on it than you would add value

I've actually considered buying another CB400F frame and building up another bike as I will have to replace a lot of the parts on mine for cosmetic reasons. There's another way of getting rid of parts!
