Help! Bought a blade engine on a whim!
I'll start with the moral of the story........never buy a cbr929rry engine, in bits, after a drink!
Question is.............. I now have a complete engine that requires a rebuild. Its going to need a gasket set and big ends...............where to go?
I also need to know everything else I will need to get this in the locost (eg wiring loom, cdi etc) as I will have to source these separately. If its
going to cost the earth, i'll stick the bits I have on fleebay.
All advice greatly appreciated.
Cheers,
Pete

I would have thought that it was cheaper to buy another good engine than rebuild a knackered one.

In a word... Haynes manual... ok two words! 
The wiring shouldn't be a problem, you can make up a loom from the diagrams in the Haynes manual. The "other bits" i.e.
rectifier/regulator, CDI etc can be bought as pattern parts or from a breakers. Couldn't tell you how much that'd be but I'd
guestimate at about £150.
Rebuilding will depend on if you're confident enough to have a go. Again the Haynes manual should take you through the process but in my
experience some things they leave out which an experienced engine builder would do as a matter of course. If you know someone who is competant in
that area, call them and buy 'em a few pints to help you out.
Whether you think it's worth the hassle will depend greatly on how much you paid for the bits + how much you'll have to pay to get it
running vs buying a complete engine from elsewhere and recouping your money via eBay.
Reckon on £1000 for a fully runnable engine... see here as an example.

Rebuilding is not a problem between myself and a few mates. Getting bearings etc might be.
Hmmmmmmm...........what to do!

Why's that? Plenty of Honda dealers about that would love to let you buy their lovely parts. 
If you're trying to keep to a tight budget though maybe dealers aren't the right place to go. However if you're talking bearings
then I'd not be happy using anything other than honda parts myself. I'd not want it all to blow itself apart on the first run just to
save a few quid.
You didn't mention if you have the injection system with it. If not, that'll be the biggest cost I'd reckon.

No throttle bodies.............its getting worse!
Breakers up the road have a set for £100 and they come up on ebay every now and then for about £40

Genuine gasket sets cost the earth (over £200 for a complete set), even a decent pattern set will probably cost you half that. Also if the big ends
have gone then its likely to have taken the crank with it, and quite likely the rods too. If its anything like the 919 carbed engine (which it
probably is) then you can't regrind the crank as you can't get over-sized shells for it. You can get the crank repaired and replated to
original diameter but its quite expensive (I was quoted ~£200) and isnt as good as new. I was told by the people that quoted me to replate it that the
material they have to use is much less tolerent to reductions in oil pressure than an original crank, and will run another bearing at the first hint
of oil surge.
Speak to Andy Bates at AB Performance (01284 703101) as he basically lives to rebuild blade engines, he'll be able to give you a good price on
the parts and will advise if its realistic to rebuild it or not, but in summary - ebay I reckon

I'd back up what Chris says.
Talk to Andy at AB Performance.
He'll tell you if its economically viable to rebuild it and, if so, he may possibly be able to sell you any genuine Honda parts you require
(such as gasket sets and bearings) cheaper than a Honda dealers as he gets them at discount himself.

If it's in bits there was obviously a problem already. Thats whats going to cost or make it impossible/uneconomical
The £85 gaskets is a bargain

OK, i've checked it out.
Its spun a big end bearing, on piston 1. As a result the edge of the piston crown is pitted slightly (above the rings). There is also some slight
scoring on the bore, but you can only see it, not feel it, so I think it will hone out. There is no ovality in the piston or the bore. May need new
piston, deffinately need big end, and prob small end. Con rod appears OK but needs measuring properly. Crank also looks OK but needs measuring also.
If crank and bore are OK I will rebuild. I crank and or bore is gone, i'll sell it.
On the positive, if its rebuilt, and doesn't need crank or rebore then it will be as new and cost around the same as a complete used
unit..................which may not be internally sound.
£85 for the gaskets sounds good, i'll U2U if needed. Does a full set include O rings etc? Thanks.

After having all the bearings/journals etc professionally measured, it turns out all I need to do is hone the bores, polish the crank journals and
throw in a set of big ends!
Well chuffed! What a bargain!
Cheers for the advice.
