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 FUEL EFFIENCY
Designed to improve all RPM ranges of fuel useage.
HOW IT WORKS
The stock carburetor from the factory is designed to meet Import Regulations ... not peak performance. 6Sigma Jet Kits provide the parts and installation instructions to modify all the circuits in the carb, to fix this problem.
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.

-Dave
• *****Hi, just wanted to say thanks. The jet kit worked like a dream and the flat spot that has always been a problem with my Daytona 1200 has gone. Very easy installation, too.

• *****Hey I just thought I'd let you know that after installing your kit my super tenere is a completely new bike!! before the kit it stopped pulling at 5500 rpm, after the kit it starts pulling at 6000 all the way to red line but hasn't lost any torque at lower rpms.
• *****I just wanted to say thank you! the kit for the GS850 was great, i hope to do alot more business with you.i just opened a small custom shop,mostly cafe racers,and street fighters, and today you made me look like a genius. again thank you!

• *****great instructions great kit it runs so good i think its time for a clutch 1999-2000 Yamaha YZF R6
-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.

• *****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 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.

***** 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.
-Tom B.
• *****Finished the mods and installed the carbs Friday night, test drove it today...roared to life and growled like a angry beast - awesome! The best part - it purred like a kitten while cruisin down the highway, and idled the same at the lights. Ok, I lied...the best part was when the light changed from red to green...unbelievable improvement in acceleration! Combined with the new air filtration system, the kerker and the jet kit, it must have 20 more HP than stock. Screams when the throttle is rolled past the 1/2 way point. Thanks a gazillion for the huge improvement!

Also, thank you in advance for sending these additional jets which I cam certain will do the trick for that bike!Have a very Merry Christmas ... to you and the entire 6Sigma Team/Families!!!
-Joseph B B R, Inc
• *****WOW, what a great fix!!!!!! Thank you sir. We went from 10 minute minimum warm up and still riding w/ choke, to 3 minutes and go like hell. Instructions were great, and we are extremely happy. Thank you for your knowledge and instruction.
