         HOW IT WORKS

            The stock carburetor from the factory is designed to meet Import  Regulations ... not peak performance. Once you install or modify an  exhaust or intake, you have put your bike into a leaner condition that  will eventually damage your engine due to additional heat from running  lean. If you notice any exhaust popping, pinging, or exhaust pipe  discoloration, you are extremely lean. 6Sigma Jet Kits provide the parts and installation instructions to enrich/modify all the circuits in the  carb, to fix this problem, and add performance you can actually feel in  the seat. 

            This is not just some jets in a box, where you get to guess at what you need, and pull your carburetor 10 times trying to figure it out, it is a comprehensive Custom Engineered 6Sigma Jet Kit, addressing all throttle positions, throttle response. Each kit is Custom Engineered by 6Sigma  to your bike and its modifications. Replacing just the jets does not  address 1/4-3/4 throttle, or throttle response, only full throttle. This Kit is for all throttle positions, and throttle response. This is a tuner kit, to get everything out of your bike, that it can give.

            We don't just send it to you and hope for the best, we don't stop until your happy. Feel it still needs more on the top end, low end, mid range after installing? Let us know and we will continue to work with you to  make it perfect for how you ride.  So, like the picture shows, we will send you as many jets as you need until it is right.

        EVERY Kit Custom Engineered EVERY Time

        MADE IN USA

        BENEFITS

        • MORE HORSE POWER

                  Designed to gain a safe 8%-10% in HP with intake/exhaust, 3-4% on bone stock.

        • MORE TORQUE

                               By addressing 1/4 throttle, you will feel more power down low,  meaning less shifting to a lower gear, and getting off the line.

        • LONGER ENGINE LIFE

                    6SIGMA JET KIT is a performance upgrade that not only increases power,  but allows the engine to run cooler and at optimum, which increases  engine component life.

        • INCREASED PERFORMANCE

                    Designed to improve all RPM ranges of performance and a quicker throttle response, helps remove the bog.

        A: Each kit is different, based on the bike, modifications, and operating altitude, so the Stage varies.



        Q: Do I need a jet kit?

        Q: Can I install this kit?

                   -Mike


        •         *****81 and 83 XT250's and another kit for my XT550. I bought one before from you and was so impressed I want a second one for my second XT550. Then 2 for my 2 old XT250's.

                  -Edward


        •         *****This is an 83 gs750 with pods and an open header at sea level. ive had 3 of your kits for customers and they all work great.

                  -jeff h


        •         *****Hi guys, just wanted to say thanks. I now have the means and the knowledge to be able to re-jet in the future ie. when I add less restrictive pipe. Before the kit was fitted, the bike would not rev past 5000 and the idle was lumpy and unpredictable but now it idles smoothly and pulls like train right up to the rev limit. Had I gone to a local bike shop I know I would have been charged more than the kit cost, and I doubt the results would have been as successfull, in fact only expensive dyno time with a trained technician might have been able to replicate this result. Please feel free to use this testimonial in any way that you feel fit. Regards.

                   -Simon R. (a very,very happy SR500 owner)


        •         *****just wanted to thank you. i installed your jet kit per your instructions and my surging problem is gone! also much more pep through mid and top end. im anxious to get a ride in tomorrow to check the plugs. top notch kit!

                  - l_______m


        •         *****Just wanted to give you some feedback on my jetting kit. It's really helped out with the the entire rev range and idles alot cooler than before. The bike is a full on wheelie machine.

                  - s_______6


              ***** Dear 6 Sigma, After installing your jet kit my 2007 yz250f is a different motorcycle. Completely eliminated the bog issue I was having. Excellent instructions and value once again.
