CBR 1000RR pros and cons?
Feels good to be back on this forum after a loooooonngggg dry period of car abstention.
So anyways ... my heart says hayabusa but my pocket says no ( although it has no say in all this LOL) and a particular kit manufacturer has advised me
into looking into the 1000RR engine. Therefor I get quite a few questions popping into my head. I know it will be cheaper but ....
a) will the engine/gearbox be ok for hillclimb/road use?
b) are upgrade parts readily available?
c) the bhp figures seem nice, but what of the torque?
In short ... is the Busa worth the extra money? I have spent so much time researching the Suzuki engine in the past, but I am totally in dark when it
comes to the Honda engine.

Hi, to me the down side of the Hayabusa is the weight its a lot heavier than the CBR1000, also they do have gearbox issues when used in competition, I
personally would go for a CBR1000 the later the better dependant on funds.

Oh! I wasn't aware that the honda lump was that much lighter. Is the stock clutch assembly ok? I don't expect it to last me a lifetime but
I don't want issues every couple of outings.
Thanks

In the early CBR900RR I have always used uprated spring for competition use (I think they are Barnett springs), I believe its the same for the newer
CBR1000. Also the latest CBR1000 have a slipper clutch as standard which can really help in the wet.
I am looking at changing to the CBR100RR for next season, I have a low mileage 2005 CBR1000RR engine but I have decided to bite the bullet and buy a
2008-2009 or later engine as the power output is better.

I've run 3 seasons on my 08 CBR1000RR in RGB, and only put a new clutch in last season. I've put a fresher engine in for this year, but
last years is still ok, just burns a little more oil, and is a little down on power.
Like any engine you need to look after it, don't cook it and change the oil regularly.
You don't need to dry sump it like the Busa or GSXR, and it comes with a slipper clutch which is great.
If you want cheap overall package then go for a CBR1000RR, but get a post 2010 engine, as 08-09s are becoming expensive as we use them in RGB.

Thanks Amalyos. Excuse my ignorance, but what's a slipper clutch?

Hi, a slipper clutch was introduced on a bike so if you change down to soon in damp conditions it stops the back wheel locking up, this also works in
a car set up.

On the bike it means you can drop a gear without fear of the back wheel locking, which is a help to the longevity of the drive train when put in the
car, as you can't use the engine to brake, as the clutch slips.

This is quite interesting. I need to get cracking on some research on this engine then. Cheers.

Thanks Scootz, yeah I was with him on the phone about other stuff 
This 1000RR engine is looking more enticing by the minute, just need to check how hard it is to get it to run on a megasquirt.

Why squirt it? the standard ECU with a power commander will do a much better job.
I am a big fan of megasquirt but these modern stock ECU's are so clever.

My friend who will be helping me out in the build is pretty handy with Megasquirt. I might need the facility to play around with maps to SVA it over
here, and get a low-ish emissions reading (i'll be paying my road tax and registration costs on this ). I won't discount the
powercommander, but the megasuirt has ample future upgrading capacity in it

just my opinion, if you had any chance of using the OEM ecu i would with out a doubt, in comparison what ever you will achieve with megasquirt will
never be as good as the OEM mapping
i would rethink your plan, unless there is limitation in the stock ecu that stops you changing certain parameters

Mmmm yes as I said, I won't discount the oem ecu. It seems that the latter engines run 8 injectors. That's good enough reason to consider
the powercomander option :-)

HI , I have a 1000rr blade engine in a hillman imp with a power commander and it runs fantastic , the engine is tiny compared to the busa lump you
can pick the engine up and carry it rather than a hoist for the big busa lump , the blade is quite quite tall because of the second set of injectors
in the air box
get the spanners out and get building !!

this post has been really handy as I have begun looking into engine swaps in the near future. Originally I planned on putting in a
and I have a few decent spec busa lump but I am now considering the Honda instead for various reasons. Are there many tuning parts about for them? Are
they easy to work on ? And are there any particular weak spots to look out for ?

is there any way to get over the hight of the engine as with the 8 injectors it does stick out of the bonnet a lot?

A friend of mine has a mac#1 with a 1000rr engine with 8 injectors.The air box is a custom made aluminium jobby with a ram air filter from a naca duct
in the nose cone.The extra 4 injectors sit on the airbox with the fuel rail.Nice clean compact system.Not cheap though!!!!!

It would be good to see how he's done this, he could probably sell the pattern as well as the height is an issue.
