Getting an additional ~11rwhp, 7% more power, with just fuel trim (PCIII) or even with fuel AND spark (PCIIIR) seems a little too good to believe (for the mods listed). It'd be interesting to verify it at another facility (set map to Zero--do a run...reload map--do a run).
FWIW I HAVE seen crazy gains (30+rwhp) by just playing around with fuel/sparks maps, but this was on highly modified engines with fugged up original maps running on after market ECU's. [/B][/QUOTE]
I never did a baseline run with my stock 1k. I had installed the TRE, and a full Ti yosh system when I took it to G-Force... it did post 153.4 horsepower, which I thought was great for no p/c and basically just an aftermarket exhaust. The reason I went with the custom map was because a friend of mine has a 99 R1 and with his full exhaust and a jet kit, they manged to bump him up from 144 to 154... I've put a lot of money into my bike, so I wanted to get the most performance out of my machine. I did some airbox mods, the PAIR mod, and was hoping to be closer to 160, and was really surprised at the 164.3.
I totally agree that that dyno runs can vary between the same model bike or the same bike for that matter. I had an issue with my power commander and brought it back a month later... they re-dynoed my bike, and it consistently ran with 1hp less. So many variances to consider, temperature, tire pressure, different tech running the dyno, etc... and I think the reason people say G-Force is 'optimistic' is because there are two types of readouts 'SAE' and 'STD'... not sure off the top of my head which one is more optimistic, but one is a good 3 to 4 hp higher than the other... i'm sure someone on the board knows the technical differences... My 164.3 is the more optimistic of the two... the other readout is 160... either way you look at it... i've got more horsepower then i'll ever need... and after spending $400 bucks on a custom map... i'd hope to see some big numbers. I know Hare Racing's custom maps are $300... and i've heard of lower prices, but I liked the guys at G-Force and have only heard good things about the shop.
If I hear of anyone running a dyno day... i'll run it again, cuz i'm curious to see the difference between shops as well. G-Force had a $20 dyno day last year... hopefully some other local shop will run that kind of promo...

I have a 99 R-1 with a k&n with a full D&D ti works system stage 1 jet kit
Dynoed at fremont cycle Center at 137.6 with I think 75.3 lbs of tourqe
Ther is a damn flat spot that I ned to get fixed with the ignition advancer

On a Dynojet, you have the option of displaying the data with and without the correction factors for temperature, humidity, and altitude. Typically cold days with low humidity will produce higher HP numbers. Hot and humid days will sap horsepower. Finally, low altitude will produce more HP than high altitude (there's more O2 at low altitudes). Hence, comparsions of corrected HP (I think this is what they mean by SAE...as in SAE corrected) are more valuable than looking at just raw numbers.

yeah... what 'nine' said
Then my 'corrected' number is 160. With moderate motor work, I could get it into he 170's, but it's already got more power than I can use... i'm using the extra cash to build a 600 racebike... don't have to worry as much about throttle control with a 600

oh...correction. I think that in the Dynojet "PEP" software, altitude is a fixed constant that you don't get to fudge with in displaying the data.
However, if you really wanted to screw with the results, you can go back into the "PEP" constants and make....err..."corrections" to the altitude...among other things, to make the numbers look "better" for the customer.

From everyone i've talked to, and what i've experienced... G-Force is a very reputable shop, and I wouldn't "think" they'd screw with results just to make their customers more inclined to come back... don't know for a fact, so the only way i'll know is to get my bike dynoed by a competitor... Would seem like something easy to prove and don't see why they'd go through the hassle and risk their reputation on something so small... also, i've read about different models of the dyno machines giving different results... I'd venture to guess that if I took my bike to 3 different shops, i'd get 3 different results... i'm sure all on a similar curve, but definitely different max hp, and torque.

doh! Don't get me wrong. I'm not saying that they do that kind of stuff and frankly, I've only heard of 1 shop (not motorcycle related) that has fudged with the results.
Dyno's WILL vary. So you really won't prove much by going to different facilities. The only thing that you need to ensure is that wherever you go, that they consistently test your bike the same exact way and that they present the data to you in the same exact format.
FWIW A 6 hp gain for fuel tuning (and especially if they did spark) doesn't seem too much of a stretch.

I think it sounds about right for a gixxer 750 to be around 120-130 HP,,,,when I had my bike dyno'd at hare they had a guy's tricked out 750 that he dumped a fortune in, and they said it put out low 140's HP........dude that's a lot for any bike let alone a 750

Well I have not done a mill and polish job on the head yet, but so far for the engine mods I have a 49state cam conversion, emissions removed, air box moded, D&D exhaust, ignition advancer, K&N air filter, and jetting.
When I first had some work done I took it to another shop to have the exhaust and jetting done. that dyno said 104. The next work was done at G-force, thats when did pulled 127 HP.

I just wanna put that 1361cc engine kit in my ZX12. The guys on the Ninja sites are getting ~200hp out of those....

I'm too cheapo to take it to a dyno myself.
With Erion Slip on and PCIII I was running 98hp. I'm running rich though... not worth the $$ right now for a custom map.

A 2002 Cali F4i made 84hp stock on our eddy current,after an Akro slip-on,BMC race filter,and PC3 it made 97hp....Robbie

Mine dyno'd at 160.5 from G force...but it was STD not SAE. I have a Full Serpent System and a power commander, TRE that is it. I watched them dyno my bike...although it does have a lot of reverberation from the pipe...and I really don't think it is running at it's best...it does pull damn hard when you are hard on the throttle. When you are tooling around it does seem to have a popping. I was swondering if they could also get rid of a flat spot at about 5-6 grand...maybe because of the SET valve removal. Do you have this problem too Qball?? If you have some time maybe you can PM me and I can find out how yours is running!!! Thanks.

KIDRR said:Just was curious to see how many people have had their bikes put on the dyno. I was wondering how much HP a gixxer 750 or 1000 put out or an R1, and how much modifications like exaust or power commanders helped. I had my '01 929RR put on after adding Full two bro's exaust powercommander and k&n air filter; it hit 134.4 Hp @ I think it was around 10,500 rpm since I can't find the print out they gave me. I never had my bike tested before the mods so I have no idea how much HP they added. Just curious,,,,,,,,
Might want to check things out on www.fireblades.org, there have been a ton of dyno runs on 929s/954s, alot of custom maps as well---unfortunately--I dont think the 2 Bros is regarded very highly by most 929/54 affecianados. I am running a Micron Serpent, with a custom Dan Kyle Map, all the crap removed from the airbox--never dynoed it, I guess I dont notice any off idle weirdness--but then again it is mostly a track bike so--it doesnt spend much time there
