Was just wondering what are some of the main jet sizes that are safe for a 2003 SXr 600? Are the stock sizes best? In my 2000 SXr 700 I run 142.5 across all cylinders which are smaller than what came in it stock and it runs great. The 600 seems to run rich which a lot of stock sleds do and so was just wondering what some of you have been running for jet sizes in the SX 600 engine. Also was thinking of raising the needle clip 1 slot due to some blubbering when in the midrange, is this a good or bad idea? Getting ready for a trip to northern Wisconsin in February and was just trying to get the 600 running a little better. Thanks for any help.
