Thinking of a jet kit...

Thinking of putting one on, over the winter months since I cant ride that often, and will have some time to put on some extras like a new can, iginition advancer, steering damper, and a jet kit I hope. Any ideas on cost? best ones? ones to stay away from? how hard are they to self install, or is it better to let a pro do it? I've been checking on the net, but not quite sure what's good/bad..etc.

I installed a DynoJet kit and it was easy. Of course I had help from someone who had done it before.

The DynoJet kit is a good one and not to pricey. For your bike it will only cost about 130.00 for the kit and if you know any one that can install it for you or help it will save you some money. Also you need to know what stage you plan on taking it to. There are a few stages to choose from and depends on how much you are wanting to do to your bike as well. Let me know and I can tell you which one is best for you to get and have done. :)

Im looking at a stage 1 now, most likely..i know someone who can help me with it, but want to try it on my own if its not too hard..how much HP do you actually gain with them, and how much does it vary through the different stages? I know alittle bit about them, but not that much so Im doing my research.

With the diff part you will be working with I would say have someone help you with it that knows about the main jet,float bowl and the hidden fuel screw on the bottom. With the different stages you will find about 5-15% increase in power. Stage 1 will give about 5% where Stage 3 about 15% in power. If you want some serious HP, add stage 7 for drag and add 80 more HP to the bike, as long as you add modifications like hotter cams, head work, and ignition timing. LOL To much money for me to do. :)

im not looking to spend all that, or go drag racing..i just wanna put on a stage 1 or 2..just to add alittle bit extra snot to it...wanna make sure I do it right though. Im really looking forward to an ignition advancer, especially with Kats known to be abit tempermental when cold starting them.

Hehehe I thought I would just add the last part. Stage 1 or 2 will be best for you even 3 would be nice. If your going to get the new pipe, I would have it all put on at the same time. They will Dyno it for you and with the new pipe and kit you will see a nice increase in power. :)

I installed a DynoJet kit and it was easy. Of course I had help from someone who had done it before. has it given you a very noticable difference in performance?

has it given you a very noticable difference in performance? Yes. I put a full Yosh and Stage 1 on at first and then about 7 months later went to Stage 3 and saw a nice change. It was worth it to me. :)

found this place online, seems to come highly recommended.. http://www.holeshot.com/

In the May, 2001 issue of Motorcycle Consumer News, they tested four jet kits from three manufacturers. Eight-page article summed up: The Yoshimura MJN was disappointing. The Dynojet Stage 1 had the best drivability/throttle response. The Factory Race felt stronger in comparison to the others. The Factory Configuration 10 was most inexpensive, and added horses in the midrange. The F4 they did the tests on pulled it's first power wheelie with this kit. So if you want most HP, get the Factory Race. If you want best driveability, get the Dynojet Stage 1. Unless it is a track bike, I would go with Dynojet. By the way, they also got good power from a Leo Vinci slip-on. Most others they tested made no difference or made less power.

I'm running a stage 2 with a new muffler on ZX-9R and got about a 15% increase in power. Really noticable power increase... hhmm 15%!! thats pretty significant...wonder how much I can expect on my 750..i would imagine its somewhat universal as far as how much gain depending on what stage I get...nice!! can't wait !! :cheers:

hhmm 15%!! thats pretty significant...wonder how much I can expect on my 750..i would imagine its somewhat universal as far as how much gain depending on what stage I get...nice!! can't wait !! :cheers: I wouldn't be so sure about that. Is your bike running close to stoich right now? Have you stuck it on a dyno with a wideband O2 sensor? There generally are gains to be had, but a little more research will probably net you more of the results you are looking for...

hhmm 15%!! thats pretty significant...wonder how much I can expect on my 750..i would imagine its somewhat universal as far as how much gain depending on what stage I get...nice!! can't wait !! :cheers: Well, stock my bike is suppose to have about 135 at the crank. According to Kaw and some mag that I can't remember. I had it dynoed on a dynojet last year after the jetting, pipe, and K&N...it put down 136 at the rear wheel. :thumbs: Not too bad I don't think...it's no GSXR 1000 or ZX-10R but I likey!! :banana:

136 at the rear wheel...NICE. :hyper:

136 at the rear wheel...NICE. :hyper: Not bad for a poor '02 ZX-9R... :cool: Nothing compared to the new 10R's 163 at the rear... :drool:

On my 00 GSXR750 I am getting 131 at the rear tire. It makes me happy. Thinking of trading to get the 1000. Now that will be some serious power. :bike: :hyper:

One thing to remember about any review like this is that the results are specific to that bike on that dyno (or track) on that day with those weather conditions. On that note, I actually had some good results with the MJN, but I would never recommend it for the street. It really is a true "race only" jet kit and doesn't work very well unless you are at 10/10ths all of the time. In addition, I almost always have good luck with Factory brand products and recommend them whenever I can (yes, I do sell their stuff). I recommend using their street kits unless you are doing serious racing. The street kits sacrifice a small amount of peak power to gain driveability, which is huge on the street (and for beginners on the track). Larry

Hey Everybody... :hi: I just had the Jet Kit done to my bike, along with a K&N air filter installation. I'm not sure what Brand or Stage, however I will talk to the Mech. who did the work and get back here with the answers. I also had a complete service done, and changed all my fluids to Synthetic. The total cost, Parts and Labor was $350. Did I get screwed, or does this seem like a fair price ? I would like to say up front that I believe it to be a fair price, especially after riding it home :D In it's current state, my Kat has a Yoshi slip on, 1 tooth smaller countershaft sprocket, and now the aforementioned Jet Kit with K&N filter and synthetic fluids. Does anyone have an estimate on what my HP would be in this tune ? Thank's... :bike: Steve.

is that price, including the jet kit as well ?? :eek: cuz if so..thats very reasonable, IMHO...one of the resident wrench-heads will be able to give you more info though. congrats on upgrading your ride :thumbs: :bike:

That is a good price you got with everything you had done. I'm going to guess on this one and say that you have stage 1 done. Get back with us and let us know. :D

Sounds like a very reasonable price...

JET KIT? Whats that do anyway? Oh yeah its carbs thing right? Sorry not carbs aboard any of my fleet of FI bikes...... :)

JET KIT? Whats that do anyway? Oh yeah its carbs thing right? Sorry not carbs aboard any of my fleet of FI bikes...... :) That's cause this guy's got too much $$$...well not too much but lots of it!! :thumbs:

You can never have too much...

JET KIT? Whats that do anyway? Oh yeah its carbs thing right? Sorry not carbs aboard any of my fleet of FI bikes...... :) So how many bikes do you currently have anyways.. sounds like a bunch! :)

So how many bikes do you currently have anyways.. sounds like a bunch! :) I can answer that....nobody knows for sure. He goes threw them so much.... :lol: Just kidding...he has a '01 GSXR 750 for a race bike and a '04 GSXR 1000 for the street.....both are very nice for their application. :thumbs: :bike:

Hey your forgetting the GSXR 600 with the 750 motor I bought for PIP. Thats mine too :)

Yeah its a ball.....

Yeah its a ball..... Hey, I was looking on your website..is that you, on the main page, in front of all the bikes? BTW..where's the latest pic of the Squid of the month, still same guy as before (in the tshirt and shorts) ...btw..those are funny as hell :smilelol:

No thats Dyno, he is a member of the WOS club as well. Yeah Lots more squids coming along with some smoking chicks. they should be up by the end of the week. I try not to show my face on the site to much, I dont want the PO-PO to get a positive ID on me......lol

hhhmm..good point! :thumbs: Are you all from around the same area, and get together on a regular basis to ride, do the track, etc ? or do you have members all over the place? :) Yeah, he needs to hide from the law. Too many Twisty Jr's runnin around... :) J/K We live all over the southern half of Michigan.... :thumbs:

Sounds like a sweet deal! If you guys ever start more of a east coast chapter of WOS, look me up..We've got some riders around here that would take part in it for sure !! :thumbs:

Hi Everybody :hi: OK, here's the info on my Jet Kit. It is a DynoJet Kit, Stage 1. I'm not bragging, but my Mech is too cool. Did I mention that his personal bike is a Turbo 'Busa ? :hyper: :shock: Catch 'Ya Later, Steve.

Let us know how you like it as well :thumbs: ...Thats a mod I hope to do next year..after my can, and some more cosmetic stuff...

Let us know how you like it as well :thumbs: ...Thats a mod I hope to do next year..after my can, and some more cosmetic stuff... Keep it on 2 wheels and there will be no more cosmetic stuff to fix. LOL :D What all do you plan on doing to it by next year besides can and jet kit? :)

Keep it on 2 wheels and there will be no more cosmetic stuff to fix. LOL :D What all do you plan on doing to it by next year besides can and jet kit? :) Just picked up a new mirror today (old one has scratches on back)..then yosh or D&D slip on can, better grips, fix scratches on right lower side (gonna ship it off to be fixed and repainted), windscreen, and braada seat cowl (www.braada.com) If I can accomplish all that by the spring..I'll be a happy camper for sure...thats the plan.. eventually, custom dragon paint job and polished rims..but thats still atleast a year away..yeah I love my ride and am planning on having it for a long time, so Im gonna stick some cash into it to mod as often as I am able too.

Hey Everybody ! :hi: Yeah, I really like 2nd gear now :thumbs: I think that is where the re-jetting really makes itself "obvious" :eek: I can actually feel the rear wheel on the verge of just breaking loose and spinning, and that is on a dry road, with the WOT only being applied after 1st gear is wound out, then 'Granny' shifting it into 2nd ! To the tuner that did my work... :thanx: :bike: Steve.

Just something I came across tonight as I was looking up what a stator does. http://www.mikuni.com/fs-tuning_guide.html Pretty good info about jetting your bike and all. Hope you enjoy it. :)

Hope you enjoy it. :) Good info there, just be aware that it is a tuning guide for aftermarket flat slide carbs for Harleys. While most of the theory is the same, there are differences between flat slides and the CV carbs found on most bikes. Larry
