My CBR 600/900 Project

[Chills]

Take one 1992 CBR600...
https://goldwing.bikepics.com/hon-cbr600-92-bikepics-03807.jpg

Add a '95 fireblade engine, some '98 bodywork, ohlins suspension, race can, a new paintjob and a whole HEAP of time...

Some guys on a canadian forum found my site recently and started emailing me... Most said good choice to mod a 600 like this and others couldn't see the point.
Just wondered what everyone HERE thinks and if you approve.. what next? Full details are on me site but in short... it's currently only kicking out 115bhp and although I could prob tune it to get more, I use this bike everyday so don't wanna screw reliability. It handles great and best of all its hidden that there's a blade engine underneath, which is how I like it for those traffic light drag races!

So what next? Nitrous?
Can it be fitted but hidden? How big are the bottles?

Cheers for any advice.

You can get all different sizes of NOS cylinders, which could be hidden under the rear seat. Looks good though, what's the weight like compared to a Blade?
What's it insured as?

Paint it green!

Or just buy a newer blade or an R1.

Interesting.

NOS system can be picked up quite cheap in the USA at the moment (about $385!), so import one of them and you're sorted. Blade engine should be kicking out more thn 115bhp. I'd expect at least 120.

I'd keep it as subtle as possible with all the modifactions so it looks like just a normal old CBR600.

[kev]

Did you actually build that yourself or did you just buy it ready built?

Very impressive mate! And if you've got a spare HEAP of time then my 1992 CBR600 could do with a similar makeover!

Hi

Suspect the exhaust is probably what is loosing you the power, as I doubt you have one optimised for the blade engine (or if you have it has taken a hell of a lot of beating to get it to fit). Also the airbox (or lack of airbox) will have an effect.

All the best

Has it been dynoed and had the carbs set up at all?

Assuming you are using the CBR6 airbox, thats a problem. Its much smaller than the blade one, and the reason the blade made so much power when it came out was the huge airbox.

Also I wouldn't expect huge increases - I think phoenix's 94 (?) blade made about 120bhp at dyno day, with a race can and dynojets.

For the Airbox problem what about putting 4 airfilters on it?, i've seen it done to a gsxr1100, doesn't take up that much space, and could improve the bhp even more .

Hey Chills,

Did you know you could fit a blackbird engine in a Blade frame?

How about a CBR600 with a blackbird engine?

that would be fun! although if I were you my next project would be some bigger discs and some pretech 6 pot billet calipers Oh and maybe some Ohlins forks to take the strain!

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

[mtthwpez]

oooh nos now your talkin! triple your power with a touch of a button!
my gpz thou has 130bhp which is plenty enough in fact its probably too much as it spins up its 16" rear wheel far too easily but i thought of putting nos on it as well!!! rip those tyres to shreads! very wsb esk

[hugo-a-gogo]

I don't mean to be daft here but is there any advantage of the cbr6/900 over a standard cbr9? you reckon the handling is better?

Have you still got the old fairings? That were on the cbr 6?

Laura: You mean the OLD CBR-F2 fairings? Nope, sorry.

Hugo-a-wotsit... Erm.. (IMHO) I'd say it DOES handle better cos the shorter wheelbase helps it steer quicker along with the narrower rear. But I've also got ohlins rear and front internals along with the raised rear end, so it turns in extremely quickly. The OTHER advantage of course is that I have blade power for £200 annual insurance!

MarJay: Really, a blackbird engine? Now that would be plain barmy in a 600 chassis... it barely handles the blade's power.
As for the brakes... yeah, it IS the one real weak point for sure.. I've outbreaked meeself on the track and run wide but for road riding, they're suprisingly strong since I changed to Carbone Lorraine pads and got braided 'oses.

Ste: The insurance guys would need to be thorough cos unless the fairings were missing you'd be hard pushed to tell. Of course if the fairings weren't there... I'd be stuffed for sure!
The radiator is from the 600 cos the blades is too big and there's NO space between it and the engine. I need to fit a fan in FRONT of the radiator pushing back rather than sucking.

Although nitrous is currently 'cheap'... if I can't use it in first and a lot of tracks ban it.. what use would it be apart from drag racing?

[Mr C]

where could you use gas on a track - you would only get short bursts on the straights anyway


you could go here and ask

www.200mph.net go the drag racing forum


loads of gas and turbo experience there and most of the big tuners are members and regular contributors

BigCC
DSD
TTS

etc.

Apparently quite a few people use nitrous on track to help keep up a bit on the straights.

You can use it on the roads, well I would. I believe it is illegal to actually use it on the roads, but having it fitted and ready to use is legal. So I doubt you'd be done for it, it'd be easier to do you for speeding and race cans.

[Mr C]

ooookay

I don't wanna argue coz I don't know for sure but I have NEVER seen a gas bottle at a track day and it sure won't be allowed in racing


I have, however, seen loads at drag strips where you can do what it's meant to do and give it a few second burst

seriously, go ask on 200mph those guys know loads about this kinda shit

hmm, my web-research says 1992 cbr 600 has a wheelbase of 1405 mm, just like a cbr900, and it weighs 185 kg, just like a cbr900

don't get me wrong, it looks like a nice bike, and the insurance issue is a different matter (if insurance companies catch you fiddling, you'll never get insured again) but it just seems like a lot of effort for not much benefit, now an 1100 motor.........

[mikey c]

what kind of mods have to be done to the frame in order to be able to actually bolt the new engine in?

thats a cbr600 f1 engine in the pic, what other engines (at least 600cc) would fit in that frame without moving the mounts?
