MAXIMUM PERFORMANCE & LONGER ENGINE LIFE

  EXHAUST POPPING?  
FEELS SLUGGISH?

These are signs of a LEAN ENGINE, a Jet Kit will fix those issues.

         *****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.

         *****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.

         *****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!
