Anyone have any experience with 6sigma jet kits? There sold on ebay and if I buy from them I can get a good deal on a jet kit for both my 09 klx250s and 78cb400t.

 

There is only mention of 'needle adjusters', not a different needle. The contour of the stock needle and the DJ needle is very different, allowing more fuel to flow in the mid range. If you only put spacers under the stock needle, you loose out on added performance.

Good point Brewster. Is any one running the 6sigma kit with first hand experience?

 

That's the first I have heard of 6sigma (jets that is).
