Sorry, some not so good weather here this weekend, and I was really busy. I will try and throw the snorkle back in sometime this week and see what it does. If that doesn't work I will pull it apart and add/take out a shim.

i am getting the dynojet jet kit. i figure i will need it when i win the ap exhaust raffle.
anyways, has anyone who shimmed the needles using this diy gone over to the dynojet kit and noticed any difference? just the needle mod. wondering if it is worth it to break open the kit to shim the needles or just to wait. |

sam, thanks for the info... but as it is now.... stock with only the snorkel removed, i did the diy shimming of the needles using 2 washers.
if i don't win the ap exhaust (although i wil. power of positive thinking , would i notice any difference if i used the dynojet needles putting the clip on the 3rd slot? or would it basically be the same as what i have right now? this is assuming that i don't change the jets and all i did was that needle mod. thanks. |

I'm not changing the exhaust on mine, as it runs great as is. I bought this bike to improve my riding skills and be safe. It is fast enough for me. With the extended warranty, if I need to place a claim, I only have to pop the OEM needles back in, reinstall the snorkel, and recap the carb mixture screws. Kelly (kkim) has a lot more knowledge/experience with the needle shimming and can probably answer your questions. |

The jet kit adds tunability and a smoother power curve. It also richens up the low end as the needle taper is very different from the stock needles. Having said all of this, you most likely would not notice that much difference in just swapping out the needles from the shimmed stock needles. The real improvement comes when you tune the mixture screws and that can be done even without buying a jet kit.
I rode around w/ my area P exhaust, no snorkel and 3 shims under the needles for a few months before installing the jet kit. The only reason I went with a jet kit was because I removed the airbox and went with the r0990 K&N filter at the same time and doing all that work at the same time made sense. If you have not bought the jet kit yet, wait until you get the exhaust and have added a total of 3 shims to the needles before you decide. I think you will be surprised how smooth the power is with just those mods. |

I just bought the washers today. Lowes didn't have them, and Radio Shack is more of a gadget store nowadays. Ace Hardware had brass #4 flat washers for 9 cents a piece. I bought 6 and plan to start adding only 2 per needle and see what happens.
The Ninja's on stands right now and I'll roll up my sleeves and take a stab at it tomorrow. |

I was able to get all the way to the carb covers.
Then I stripped a screw head on the right carb. I tried for half an hour to use everything at my disposal to get a grip on that screw for naught. What did they make those things out of, lead?? I decided enough was enough and put my Ninjette's clothes back on. I put everything back together, making sure the bike was able to run before putting the fairing back on, and it's back to its old stock self. I did get healthy understanding with everything I did today, though. Perhaps I'll try the DIY throttle slop fix. |

you should use the JIS screw bits or screwdriver. it firmly grabs the screw and it will remove very easily.

also, if you use an offset driver like the skewdriver i have, it will make the job a lot easier as well.

I have been there and done that myself... What I ended up doing was pulling the carbs right out (not as hard as what I thought) and using a pair of vice grips to get the screw out. I have since replaced them with allen head screws and no more problems

sorry to hear that. yes, you need to be very careful with those screws and apply downward pressure before you apply sideways torque other wise you end up stripping the heads. the real solution is to get the JIS screwdrivers, but I have had mine off/on many times and the screws are still in good shape, so there is a method to the madness. Is there enough room to grab the screw head with long nose vise grip pliers? what DIY throttle stop fix? |

I was thinking vice grips, don't have a pair of needle nose but there's hardly enough room to maneuver a screwdriver shaft, much less anything bigger. I didn't even know JIS screw bits existed before attempting the mod!
I could have sworn I saw a throttle slop fix that involved a zip tie on the kawiforums, but I may have been dreaming it - I'm beat now. |

yes, there is a zip tie mod to make a quicker turning throttle.

I'm thinking I may be able to attack that stripped screw from the side. Will save that for another weekend, though.

If you have a way of catching any debris by covering up everything surrounding the stripped screw head then cut into the head and make a deep slot with a Dremel cutting bit (I'm assuming it's a buttonhead, I've never looked at the carbs myself) and then use a flathead to unscrew it. I've used this trick even on threadlocked screws, works well.

hmm... andy, i never thought of that. i gotta file that one away in the old memory bank. i got one of those "stripped screw removers" from sears. used it once in the past. similar to the grabbit, but no need to pre-drill it.

it's a trick I use a lot on RC cars. Someone in that hobby showed it to me once. Those screw removers work well too, I was always too cheap to buy one

what do you mean you dont have to remove those black things to remove the needle? how else would you get to the needle it looks like it is under them right? ( the 2 round black things that you could strip the screw head easily on )

Angelo, You must remove the carb covers. the needles are below them. I believe this is what you are talking about.
You do not however have to remove the rubber diaphrams that the needles sit in, a set of tweasers, or small long nose pliers will get the needles out.

No worries Angelo,
I suggest if you do get a Jet kit, read up on the DIYs etc on here and attempt it yourself. It really is not hard at all, I was surprised, taking the carbs out (can be done without taking them out though) looks a lot worse than what it actually is.

Hey guys, I just got a green 250 and I'm planning on going home to shim my needles and do the snorkel mod this weekend (I'm at school bike is at home )
Anyways, I read on the kawiforums that if I do this mod, my bike runs a slight possibility of being too lean at wide open throttle, and that runs the risk of burning some engine components. Anyone know anything about this? I currently have an AP full exhaust on it. I'll probably do 3 washers, but does anyone know about the burning / overheating the engine issue? I don't wanna do this if it risks my engine being too lean and overheating at WOT. Any input is appreciated, thanks. |

Wen, 3 washers should be fine, kkim was running 3 washers with the same setup, so you should be fine.
Just feel what the bike is saying, take it for a ride and WOT it right to the redline, notice how it pulls, do the mod and test it again and see how it pulls. It will be noticable if the washers are not correct.

I don't think the washers have anything to do with a lean condition at wide-open throttle and high-revs. At that point needle will be almost all the way out whether there are washers lifting it or not. I'd think the question is, with the snorkel removed and a more free-flowing exhaust, can the carbs get enough fuel into the mixture to maintain the proper air/fuel ratio at max-rpm, max throttle?
I don't know the answer to that, but if the answer is that the carbs can't, then there may be actual needle changes necessary, and shimming won't fix the problem. If the answer is that they can, then once again the washers don't matter.

Lean conditions at higher RPMs can be corrected via larger jets. Of course, that will also cause richer conditions at lower RPMs, as well. YMMV
