Make my FireBlade faster (without my wife knowing).

Got an 02 954 (mint) in silver and black. I'm an accel junky and need to drain the lizard. Problem is the old lady is always thinking 'self inflicted destruction', so has to be incognito. My current accel mods are, 2 bro's bolt on exhaust, PC (old) with a 2 bro's map. Love the current power but as everyone should want, I need some more. Have the cash for mods but the old lady is pissed that im even thinking of more. Apart from raising the intake charge psi, looking for the best 'bang for buck' for more power. Need some advice... should i go injectors, cam/valves, bottom end (stroke, bore), aspiration etc. Just cant slap on some flashy turbo or nos can, or the wife will have my balls (and she already does but that's a conversation in its own). I can get away with "Ohh it broke and I need a rebuild" or something similar... Need advice from the pro's.

"Drive it like its stolen!"

Porting and boring. Let me find an article about boring these motors that I had read. BRB

Re: Make my FireBlade faster (without my wife knowing).

A slip-on exhaust gives you nothing but noise. If you want quicker acceleration cheap, get a 15T front sprocket and 520 chain conversion and hit the gym. Weight loss is the cheapest way to increase your power / weight ratio. You can also get some magnesium wheels to reduce unsprung weight.

Re: Make my FireBlade faster (without my wife knowing).

In what would be a welcome improvement for the purchaser who aims to own the bike for the really long-term is the fact that the bigger pistons slide up and down in new cylinder sleeves pressure formed from sintered aluminium powder. The bonus comes down the track, in later years, these new sleeves can be re-bored, to a maximum of 0.25mm oversize, this is becoming increasingly rare these days. Honda also say the material that makes up these new sleeves provides better wear resistance and heat dissipation, I have no science degree so will simply take their word for it. I guess a lot of racers will immediately be doing that overbore to get them from 954 to 960cc as for them every little bit counts.

So your saying sleeve the cylinders and go over bore pistons (over bore for power/compression ratio and sleeves for longevity)? So saying I sleeved the cylndr's and ran up to a .25mm overbore (without a top end mod), what can I expect to gain (modestly)?

Re: Make my FireBlade faster (without my wife knowing).

Have the exhaust (full bolt on 2 bro's manifold and pipe), flapper mod is modest at best (easily just clamped, I saw little performance increase from this), and have the best map I can find for my exhaust (beyond a tuning shop). Looking hardware here. Cam, stoke, pistons, valving etc...

Re: Make my FireBlade faster (without my wife knowing).

Im curious about head porting. Anyone with any real world data on this? Have the ability, worried about materiel depth. Hard to find any figures about how much you can remove and retain flow/thermal efficiency. Any insight into porting/polishing?

Re: Make my FireBlade faster (without my wife knowing).

Any idea as to the cost of sleeves and over-sized juggs?

oh ok. I always considered bolt on/slip on to be the same. I would still suggest the flapper mod and a custom map

Re: Make my FireBlade faster (without my wife knowing).

I don't think you have to buy new sleeves. I got that bit from page 2 of this article...2002 Honda CBR 954 RR Fireblade - Ride Review - Page 1

I also don't have any info on pricing but the all mighty bladeracer might have some more information on this.

Re: Make my FireBlade faster (without my wife knowing).

What I got from the little bit you posted Midwest, was that it was the new motor. AKA the 954?


As for porting and polishing, You would do best to find someone who is knowledgeable in the feild and having them do it. It is best to have a flow bench for such a thing as well.

An Magnesium wheels, as great as they are. I dont think you want to go out and spend more then the bike is worth. Looking at wheels for my bike, its something like $5000.. Thats almost as much as I paid for the bike brand new.

Me too, all I could think about is that the 954 is about the last model with a trunk large enough to hide a NOS bottle.
