The mid-range is very smooth, and pulls from all rpms/throttle openings without surging or hesitation. Very happy with this setup until my EFI kit gets here, then I won't have to worry about jetting anymore. I also replaced all 16 screws that hold the caps and bowls with M4x16 hex head screws.

update: Now 2 turns out. Tried one turn but it was not running well. Getting a solid pop when I chop the throttle, and some popping on low-throttle deceleration. Would like to get rid of that... but any more out on the screws and I get the symptoms of over-rich.

I would go from 2 turns thru 2.5 and it would fluctuate and/or drop below the set RPM. the 42 is critical IMO. My theory is the 40 is to much fuel over the air in the mixture, the 42 makes it a better blend at 1.5 turns out. all dirt bike tuners say if its over 2 turns you need to go up one on the pilot.

Tried diff mainjet sizes and diff A/F mixture. When warmed, 90 mainjet was best. I really couldnt notice a difference between 88 and 90 except with 88 i had to do 2.75 turns OUT on the A/F mixture screw. I just didnt like how my idle was, and rather than messing with the pilot went back to 90 mainjet.
I think with the switchover to LeoVince i will get at least 1.5 HP more. The AreaP doesnt seem strong enough. Currently i am at 90 mainjet, 2 turns on A/F mixture screw. I am going to try out another carb with Dynojet kit soon. Quote:

Very smooth power delivery. Needle was originally set on 3rd clip and ran too rich. Then moved to 2nd clip and ran better but a tad to lean, had surging in mid range. Added a washer for half adjustment and runs great, surging gone. This is probably where the jetting will remain on my bike. After I get some more seat time I may tweak more.

MISCELLANEOUS INFORMATION ABOUT YOUR BIKE’S JETTING SETUP: installed jet kit with 98 main with areap exhaust and stock intake and 2 washers above E clip, pulled good throughout the rpm range. Installed pod filters with stock runners and crankcase breather, started with a 104 main and stock pilot. Wouldn't start without choke when cold, low end was lean and pulled ok from 6k to 8k then leaned out till redline. Jumped straight to a 108 main and reset idle mixture screws 2 1/2 turns, low end still lean, idled erratically, slight pop on decel, after 8k pulled great. Installed 40 pilots and put one washer under E clip in third position. Still needs choke to start, idle is a little off, pulls pretty evenly from around 4k till redline. Synced carb, idles a little better but still off, can't seem to get it "dialed in" right. took it to a dyno day to see where its at, 30.8 hp, seems pretty good, going to fiddle with the mixture screws to see if I can make the low end better, if not, it'll stay as it is. |

Tuned idle mixture by idle speed and sound. Throttle returns nicely after blip. Started with 108 main, switched to 105 main, and tried 102.5 main. 105 provided best feel to redline. Started with clip in 3rd position, ran decent, 3rd position with washer ran decent but rich 4th position overly rich. 2nd position with washer ran great. 2nd position mid range feel nice and crisp. Engine would bog and stumble around 2-3K when taking off from stop. Changed float bowl fuel height from 17mm to 18mm, took care of low end stumble. Bike pulls beautifully from 3k to redline. Plugs look good so far, going to keep this setup for now and check plugs again after tank of gas. Only change I'm looking at making is possibly going back and adding a washer underneath the needles. |

Going to need help when my exhaust comes.
I've been reading up on the whole jet kit thing, and I would like to know if there is anyone in the Riverside/Temecula/Ontario part of CA, that could help me with a baseline to get started with. Once that exhaust comes in, I would like to fidget with it as little as possible. If there is someone close to my area, I can start with what they're running (with altitude and temp adjustments made) and made adjustments off of that.
An extra set of eyes might help too, once installation time comes. Dinner is on me! Well, actually it's up to the wife, cause I can't cook unless it's a peanut butter and jam sandwich.

Hi everyone, I'm having problem with mine, after pulling the throttle, the RPM slowly goes down, is this something to do with the mixture? After installation of the kit, the mechanic sync the carbs, but I don't know if he played with the mixture screw. The mechanic did not removed the snorkel too. Please help me, the bike is stock on the garage because of the RPM slowly pulls down whenever you rev the throttle. Thanks in advance.
By the way I used the 98 sportisi main jet and the 38 stock pilot jet, I did do the second from top clip needle then washer then clip then washer thing in the needle. |

It's linked from the main DIY sticky thread. That area would get way too busy if every useful tech thread was sticky, which is why that reference thread helps organize things.

So curiosity got the best of me and i sprung for the Factory Pro stage 3 kit for the needles.
Did not ask anyone but was hoping it would come with 108 main jets.... it did not. 110-115's and a 40 pilot. So my current set up with stock needles 5 washers, 40 pilot, 110 mains the bike runs good 1/4th throttle to redline, rich at 1/8th-1/4th throttle. I was gonna go back to the 38 stock but instead put in the factory pro needles today and kept jets the same. I guessed on the clip settings based on my stock needle shims and comparing the two different needles. Figured i would just share some pictures of the two needles side by side. So FP needle on the top and the stock needle on the bottom. In the full needle shot it is easy to see how long the FP needle is compared to the stock needle. Even with the factory having the clips in the #4 position. |

EXHAUST MODIFICATIONS: Full 12" AreaP system, can repacked with moose racing fiber glass JET KIT OR STOCK? Kit BRAND OF JET KIT? Dynojet Stage 3 MAIN JET: 108 NEEDLE AND CLIP POSITION: DJ needles, eclip in 3rd position with two washers on top MIXTURE SCREW SETTINGS: 3 1/2 ELEVATION: 400~600 MISCELLANEOUS INFORMATION ABOUT YOUR BIKE’S JETTING SETUP: Bike feels amazing from 5k-redline, throttle is still snappy in the mid range. It's now possible to do small wheelies : ) considering i have a 15T front sprocket that's a good feat. There is no hesitations or bogging, misses half throttle to wide open. Motor sounds way better with all the intake noise, a little to loud at times. The only issues I'm having Is the low end idle 1/4 throttle. It's having a hard time holding a consistent idle have to re adjust after the bike is warmed up. I've Messed with the screws from 2 1/2 to 3 1/2 and it still feels sluggish to take off. It's like it's trying to catch up, and hesitates to go. Once it hits 4.5k it just goes and comes alive to redline. Also when it's cold if I apply the choke, Idle drops way low and engine cuts off, unless you blip the throttle. I might turn the screws out more, which usually means I need a bigger pilot... I will also try and add another washer see if that helps any.. But for now I have to ease into the throttle or just rev it to 2.5-3k and take off..

Turning the screws out means more air, you need more air because you already have to much fuel (rich). 3.5 turns out is a good bit, are you running the stock pilot or #40? if you have the 40 in I would go back down to the stock #38. if you still have the #38 then I would make sure the needles are seated correctly and everything else is good, vac lines, slides, diaphragm's ect... if that all checks out, give a lower pilot a shot. Other reasons I think your idle circuit is rich is you say choke kills it. Choke gives more fuel, since you are already rich the choke makes it even more rich and poof it stalls. other hint, you say if you blip throttle it doesn't stall. By twisting the throttle you are engaging main jet circuit which in the 1/4-1/2 throttle range is controlled by the needle. Therefore getting out of the idle circuit which is to rich and causing the stall.

I fixed it, turn the screws in till the engine almost cuts out, then back out too set idle. I did this on both and sync the carbs, problem fixed. I guess I was way to rich... And I have the stock 38s in it. Plus there was also a small vacuum hose disconnected. I didn't realize this till about a hour in of trying to sync the carbs. No wonder it kept fluctuating..

Yes - if you add choke and it runs worse, you are already rich. Generally, adjusting the idle mixture screw to get the highest idle speed is a good start. There are times when you will want to go slightly richer on that adjustment to help get a smoother transition to the needle. |

Most of my experience is on carbs with air-bleeds also, so I have to stop and think about it when tuning the Ninja. |

judging from last post apparently I am the only person still messing with their getting
So latest updates here is my latest set up YEAR: 2012 w 10k miles INTAKE MODIFICATIONS: POD, Kleen air removed, PSR block off plate EXHAUST MODIFICATIONS: Nojima moto GP full race JET KIT OR STOCK? Kelhin jets, FP needles BRAND OF JET KIT? bought jets from jetsrus MAIN JET: Kelhin 108 Pilot Jet: #40 NEEDLE AND CLIP POSITION: Factory Pro needles, clip in #3 position with 1 of their shims underneath MIXTURE SCREW SETTINGS: haven't messed with yet ELEVATION: 0-3000 feet MISCELLANEOUS INFORMATION ABOUT YOUR BIKE’S JETTING SETUP: BRT-Tis programmable, timing advanced over majority of range compared to stock. Bike runs good through all throttle positions. Runs best at WOT from 9k-12krpms Bike feels lean at 1/4 -1/2 throttle positions all through lower rev range. will shim needles soon. Bike feels good up top with the 108 at WOT, I feel the power drops off more than with the 110 mains past 12k rpms which kind of makes sense, but I feel like the bike spins up quicker from 9k to 12k. Will run the 108 for a while before I make a final decision. After I shim the needles the bike will probably feel a good bit better everywhere.
