300SX Jetting/Setup ?'s

Recommended Posts

09 250SX getting a 300SX kit. Have a few jetting and dimension questions.

Keep in mind hare scramble/gncc style riding. Currently: NECJ 3rd clip, 40 Pilot, 160 Main. Southeast US (NC/VA/SC Primarily), 500-2000' in elevation typically. 

I know that the kit says it runs with the 250 carb jetting, but stock jetting sucked. What jetting have you all run in this swap? 

Also what did you all set your X and Z dimensions at?

Your jetting is a good start 

maybe a NEDJ needle clip 2 ( same as NECJ vlip 2.5 ) if you want to lean out the 1/4 - 3-4 range and maybe an air screw adjustment might be needed
