Hi all, I just got '03 Z1000, would like to know any tricks to get more low end power out of it.
Here are the generic tricks I have used over the years, any comments:
-Advance Timing
-Milder Cam (Later model, will it fit?)
-Longer length exhaust headers (and why is it 4 into 2?)
-Add on fuel controller, what settings? I have a Dobeck and have the cruise and acc pump settings at stock
-Up compression (aftermarket pistons?)
-Monkey with secondary throttle valves?
-Open up intake, different air cleaners?
Thanks
P.S. Don't tell me to drop the gearing, that's not what I'm asking here.

wrong bike for what you want. you might do something to help a little. the trade off might not make you happy. sell it and get a 07-08 . that bike has more low end power and looses about 10 HP in the top end. if low end grunt is what you want the 2010 ZED is the answer.
the 07-08 Z1000 is not a torque monster and it has smaller cams,throttle bodies and a heavy crankshaft.

If you have stock gearing, install a 15t front countershaft sprocket. First gen Z's come with 16/42 gearing stock, fyi.

By doing so, it basically gets into the powerband almost instantaneously unlike with the taller gearing it takes a second or so for it to 'get up and go' when you first chop the throttle in the real low rpm's. Whack the throttle at a low rpm with a 15T and boom, it has that nice 'lurch ahead' as I call it similar to what a V-Twin feels like when you hit hard down low. It's defnitely worth a try as you can pick up a new CS sprocket for around $20-$30....

the stock 03-06 Z 1000 gearing is already on the low side. 5,000 rpm at around 70 mph. i like my gearing but i do not think i would like it lower than it is now. the lower gears almost make 1st gear worthless. i 100 % understand changing the gearing will make a HUGE improvement in performance. im a old fart and i just do not like riding a bike that is geared to low. it takes some of the fun out of doing 70 mph. from stop light to stop light you are shifting like mad all the time. as long as he understands the trade off GO FOR IT. their is no free lunch. i had a 64 ford falcon once with 4.56 rear end gears, it was fun from a stop light, not on the FWY.

I know what you're asking and the answer is no, there's not any way to do it. Removing the secondaries will give you more instantaneous throttle response but you'll run very lean until you remap your fuel. The best way from what I've read would be to get a Muzzy big bore kit. You have to ask them for it because it's not on their site, but they will make one for you. Or, if you own a bank or something, you could supercharge it for about $5k. You'll get anywhere from 205-225 hp out of the various kits available.

trade for the 2010-2011 gobs of low end.anw you can add even more for about 1200 muzzy full exhaust PCv and filter. hard to keep the front down.

block off the emissions. the reed valves on the valve cover
sorry to to dispute your post. that is only a feel good mod. it will not make the bike faster. i removed all the smog crap off my ZRX a few year back ,including that reed block off. i wish i just left all that stuff on their. mostly the reed block off is for backfire elimination on decell with a loud pipe.:dontknow:

Thanks for all your replies. I just sold an 06 Gixxer 1000 (basically had too much $ in it) to buy my much cheaper 03 Z1, so I am sticking with it. The Gix has great low end, matter of fact had great everywhere power, so I'm kinda spoiled.
No, I am gonna leave the gearing as is. Well, I'll try some little things and report back if it makes any difference.
My VN800 cruiser has those reeds in the head, and I disconnected them just to get rid of all the extraneous crap, and I did not feel any performance difference.

I know how to get top end power But not bottom end. Maybe you should have bought a B-King or V-MAX :confused:

I raced a CBR600RR, a 636, a Superhawk 996, a Suzuki M109R and a mid 90's Smokin Joes CBR 900 from A to B, 2 miles, through a couple twisties, but mostly straight and sweeping roads on my '03 Z and left them in the dust. The closest was the 636, which surprised me, and he was at least 1/4 mile back when I stopped. The Z is plenty fast to compete with other bikes and you'll never get left behind, but I understand the want to make it faster too. I really want a supercharger. Really really really really really bad. But last time I looked at my bank statement, :headshake:.
