    I looked into the 6 sigma kit on a bike that I got rid of so i never ended up buying it. Their kit is great if you have aftermarket exhaust and not a lot of jetting experience. It includes a spacer (washer) for the needle and a set of jets. Did Husky still use the TMX in 2011?

    Yes from 2011-2014 they still used it though I have heard it called the Mikuni TMXX. It has a kidney bean shaped slide.

    Personally I installed a JD Jet Kit for mine. It comes with a different nozzle, a few mains, a pilot, and two needles. Looks like six sigma comes with a needle adjuster rather than their own proprietary needle like the JD kit. Could work but I've found my JD kit to work good - part of the reason could be the different nozzle which is also a popular mod to Honda CRs that come with the TMX (01-07).

    I'll add a recommendation for the JD kit. :thumbsup:

    Thanks guys... I was thinking of doing the sigma kit because of the price. Looks like a lectron wouldn't be a crazy upgrade either.
