Anyone tried a 6 Sigma jet kit?
Gday, been checking out jetting for my kdx200e and noticed the 6 Sigma jet kits on ebay, was wondering if anyone has tried these kits and if so what were the results?

Do you know who manufactures the jets themselves? I've heard bad things about aftermarket jets, I always stick with genuine Keihin Jets https://www.jetsrus.com/a_jets_by_carbu ... 25-xxx.htm

Does this kit include the needle(s)?
If this kit is just the main and pilot, I wouldn't even bother.
And if it includes the needle, I probably still wouldn't bother. It is not that easy to come up with a good quality needle.

Re: Anyone tried a 6 Sigma jet kit?
I've read quite a few things on the net saying it's a re-packaged dynojet kit but what truth there is in that I could not say as it is the internet after all lol.
The kit comes with jets, needles, nylon shim for needle, drill bit and instructions for drilling slide, and something else I think I have forgotten, can purchase stage one through to seven depending on what mods are done to your bike, I still had no replies on here when I checked earlier so I thought I would just buy a kit and try it out, my bike should be back together next week (provided parts I've ordered arrive on time lol) and I'll report back to you guy's with the results after I install them!

Re: Anyone tried a 6 Sigma jet kit?
Being that there are 7 levels depending on mods, I wouldn't bother. While mods certainly do play into the jetting, so does your elevation and temperature... every bike is different. A level 7 kit isn't going to work the same for someone who lives at sea level as it would for someone riding at 6k feet. I'm going to guess that those kits don't take that into consideration... I wouldn't bother...I'd stick with all Keihin stuff if I were you.

Re: Anyone tried a 6 Sigma jet kit?
I am not buying that 1-7 thing. I have owned two KDXs at the same time with the same setups. Both required different jetting. Not a big difference, but a difference.
The needle is what is going to give the engine its personality. Everything else just makes it run properly.

Re: Anyone tried a 6 Sigma jet kit?
Well I don't know a great deal about jetting, Ive already bought it so I guess I'll just have to wait and see now, is the first KDX I've owned and I've never ridden it before got it as a basket case and rebuilt it, will run it in with original jetting then swap them out afterwards, I got an email from them today asking for mods and elevation so they could make my kit up for me.
I got a spare parts bike with mine and they both have the same jetting which is 155 and 75 which sounds way off what people are running on here,

If your bike has stock jets and even if you are at sea level, anything reasonably leaner will be a big improvement.

boguuuus !
just use the kdx jetting guide process and do it yourself. it's very easy and thorough.

Nothing to report on the jetting kit yet, am beginning to wonder if it will actually ever arrive....

6 Sigma is the best performance mod needed after air filter and exhaust Ive tried. I put a 6 sigma kit in my VTR1000f 07 Firestorm. It included
*Main Jets
*Pilot Jets
*Needle Adjusters
*Nylon Needle Spacers
*Slide Spring Modification
*Drill Bits for
*Slide Hole Modification (optional)
*Carb Schematic
*Carb Synchronizer Tool
Step by step instructions with photos for ease of installation.
So it's all inclusive of more then just the kit but pieces needed for carb slide mod and asks you what altitude you will be riding in generally and if you have a high flow filter (K&n oiled paper vs stock) and if you have certain types of exhaust on it (stock-open pipes and everything in-between) before checking out and is all for under $60 instead of the $100+ for a JD or dynojet or keihn jets. After installing them I found it had shifted the power delivery to mid and top and also allowed for the motor to be revved out with ease and at the same time maintaining fuel consumption to a minimal even wide open. Firestorms are known for being thirsty motors and this jetting allowed it to be ridden harder at higher rpm but still consumed the same amount of fuel as before re-jetting . It regulates fuel more efficiently so as to make the most out of atomising the mixture. It's one thing to throw more fuel through an engine to get more HP out of it but if you don't make the mixture 100% fully ignitable it has to be properly atomised. These jets are so incredible that they have accomplished this since it has done what is supposedly the impossible. It's allowed the bike ride at a higher rpm favouring the peaky side instead of the torquey side as it was designed to and created a harder revving more efficient livelier motor from the sedate stock tuning with equal fuel consumption at a higher rate of knots. So seriously what would you rather, a custom made set of jets with altitude specific conditions and options for hi Flo intakes and exhaust or jets for double the price that do not provide as much improvements as 6 Sigma????? It's pretty obvious for me. $60 6 sigma has sorted everything I needed while providing more adjustments and improvements than stock. Dynojet, JD and keihn may have the market in exposure but 6 sigma has everything they provide and more with a unique take on improving flow from intake to exhaust at only half the price.
6 Sigma Jetting is #1 for efficiency, power and value for money. Try it asap.
