I just installed the JD kit + 3x3 in my previously unmodded DRZ, except for the 14 tooth front sprocket. Test riding @ 5,500-6,500 feet in southern Utah. Did not get the big boost in power as expected, so I switched to blue needle 3rd clip. This gave an improvement, but still not optimal, I'm thinking it might still be a little rich as no choke was needed this am. So which way should I move the clip, up or down. Thinking maybe changing the jet to 145 instead of 150. What do ya'll think. Haven't checked the plug yet, was a little dark with the red needle in. I know if the tank comes off something is gonna change in the carb, I won't just check the plug and let it go. Enough rambling, sorry.
