I purchased a 450 xc the other day and noticed a bog in lower rpm range. It has a full hmf exhaust and a jd jet kit already installed. The jet kit is running a 180 main with a 45 pilot and the blue needle. I do not know what clip it is running and just wanted a suggestion for what settings I should be running for the carb. I am ridding at sea level-3000ft at 50-80f but occasionally run at 30f. I am also going to double check if the o ring mod has been completed for the accelerator pump whenever I actuall get the chance to look at the carb.
