I know the 2009 500ss motor has a jetting issue. My problem is I just bought a used 2009 GTX with the 500ss motor and will not be able to ride it for some time. I have read all of gadgetguru's jetting posts and was wondering if I should just change the needles and jets as gadget did now before ever riding this sled. IF BY CHANCE YOU READ THIS GADGET, can you tell me if you actually measured the 2010 needles?? Some say raise the stock needle and increase the pilot to a size 20. I read gadgets changes and he decreased the pilot to a 15 and the main to a 390 (I think)plus used a different needle alltogether which was shimmed in addition to the full rich clip position. Thanks for any info. PS. Has anyone actually had the ECM remapped with less midrange advance?
