Let's establish a ZX7 Carb settings database

I'd like to establish a database of carb settings for ZX7's, ZX7R's & ZX7RR's to help everyone with carb issues. I'd like to see everyone who knows how their carbs are set up post the following info:

1) Year & model of your bike
2) What carbs are on it
3) Carb settings (all of them you know)
Stock or jetted?
Pilot jet size
Main jet size
Needle setting
Mixture screw setting
Air jet sizes(fcr's)
Accelerator pump setting (fcr's)
Air filter
Idle speed
4) How does it ride? Any flat/dead spots
5) Air filter
6) Spark plugs (Brand and Number; example: NGK CR9E)
7) Engine mods
8) What exhaust are you running?
9) Your altitude above sea level
10) Where are you located( Country,State,Province)?
11) Optional: post a picture of the bike you're referring to.


I will be posting mine and I've done it several times to help others in the past. I'd really like to get a solid database together for everyone to be able to draw from when they have issues.

They're almost identical to my 93's. I will post them when I dig them back up. Hopefully others will post their settings so we have a very good cross roads of settings to study and learn from.

Slow air screw...
Pilot screw...

Same?
There is only one thing on my carbs that I can turn and I believe it to be the "pilot screw".

Nevermind... I guess stock the "slow air screw" is a jet originally.

That's what I like about you, Turbo. Instead of looking to external factors you consistently look to yourself to provide the improvements first.

In a day and age where everyone's playing the blame game and looking for excuses it's refreshing to see a little discipline, determination, and self-efficacy.

You know, if someone within the forum knew a bit about php, a database could be made that is searchable by any parameter. That having been said:
95 zx7
FP jet kit titanium with different needles on inner and outer, mains are same across the board.
Mains:180
Idle:factory
Needles: second from bottom
Floats: 14.5mm
Kleen air mod..float mod
Full titanium muzzy
No screen and k&n filter
Carbs came with dyno junk , removed plugs and plugged drilled holes in slides.
Started with Fp recommended 190 mains, was too rich, dropped to 180. Kit came with 180,190 and 200.
Started with 3rd clip pos as per Fp
I will go over my float setting and findings as this may help others.
13mm: too rich, wot at low rpm caused bike to bog down and try to die.
15.5mm: too lean, bike needed choke to start even when hot.
14.5 mm: bike accepts wot at low rpm and starts easily when hot without choke or touching throttle.

Screws are at 2 turns.
After all settings bike seems at the best I've had it so far. Doesn't want to wheelie per say, or pull so hard it wants to come out from under me but I did light the rear tire up in second gear rolling at about 20-25 mph when I got on it hard so I take that as a good sign.

I heard the dual electrodes were good for low-mid rpm ranged bikes but not high rpm sportbikes because of how rapid the spark plugs fire. This is what I've heard. What's your experience with them?
