can only reply as the owner of a Blackbird.
carbed upto '98, FI '99 to present.
Generally regarded as the stronger and more reliable of the Super Tourers but down on power alongside the Busa and GPZ.
I here that they are prone to oil starvation problems in cars and need dry sumping. However I got a mate who raced F1 sidecars with a highly tuned
blackbird powered unit, and AKAIK it wasn't dry sumped, just baffled.
hope that is some help.

Hi,
Front or mid engine ?
If its up front you need minimum sump baffle and that's gives no guarantee of protection from oiling problems, baffle plate and something like
an accusump should be 95%ok, dry sump 100%, if its mid mounted then I ran one with std sump for 2 years no problems including track days and racing.
blackbirds suffer from oil starvation when front mounted (inline) and #3 big end gets knocked out every time.
If you go injection then ideally you want the pump off the bike along with all the rest of the loom etc, you need the loom ecu etc if its carbs
too.
What they like ? Got plenty of low down grunt more than a blade R1 etc, mine makes just over 140 at wheels with custom exhaust and tuned by TTS dyno
jet etc........

Hi
I have a carb blackbird and love the engine, pulls very well from low rpm and find it excellent on the road.
i have modified/shortend the sump with a bffle plate to help oil surge, also fitted a 4 pint accusump to assist.
have been testing it on the road for last 2 months and the oil pressure is at 70 psi even on fast right hand bends which is where the probs normaly
are.
i am in essex so if ever want to view the set up more than welcome.
great engine for the road/ (track if modified)
i had previously been just using just a shortend sump for 6 months on the road with no probs so would say if only using on the road this may be all
thats required.
hope this helps

carbs, they told me they have seen more though on others, also advised a shorter exhaust for peak power which I will have this time around but it was
helping lower down (from collector too silencer)
Cant speak highly enough of them, i took it in running what I thought was well, scared the F*** out of me just putting it back on trailer, not cheap
though.
edit too add, the chain drive helps with power too, would be interesting too take engine out drop it in one with prop n diff and see what it makes at
wheels.

Thanks Jon
Correct not cheap i will need air filter, dyno jet kit + dyno time around £300 all in,
i think mine is running ok but is running rough at high rpm prob lean at top end.
running std air box at present so hopefully will see some improvements.
Have put on a r1 can to get the db down for the track so will restrict it slightly.
I agree on the engine being great as you know my brother has a zx12 and mine is much more driveable and user friendly on the road at not far of the
pace.
cheers Sean

I've recently bought a Fisher Fury Blackbird (carb'ed). I know its cheating but I don't have the time to build my own at the moment
- much as I'd love to.
Anyway its running a mistral baffled sump and a 4 quart (~4 litre IIRC) Accusump. The previous owners (hi Brian if you are reading!) recommendation
was - you'll don't need the Accusump on the road but remember to turn it on during track use with sticky tyres.
He forgot once and buggered the engine (I believe beer was involved the night before)
Do you think this advice is correct? What if I put sticky tyres like A048Rs or R888's on it for road use. I know you shouldn't be going
10/10ths on the roads but you're still going to have a lot more grip?
What about similar tyres (I've got some ACB10's) at somewhere like Santa pod where its all going in a straight line - am I ok from surge
there?
Its currently overfilled slightly to halfway on the part of the dip stick where it tapers - is this what other people do?
Thanks in advance for any replies!

I just sold a mistral sump and after speaking to them they advised me to mark the dipstick at 60mm then fill to this level to compensate for the
shortend sump.
i did not fill as much as this as the accusump is on all the time even on the road.
if you have got it use it, you would be kicking yourself if something happend and it wasnt turned on.
as previously said on the road i had no probs with baffled and shortend sump the accusump is extra protection for the track
(when i eventually get there)
