Suzuki drz s 400...

Recommended Posts

I was once a member of this group a few years ago... I’m sure there was a topic of how to make the Drz s a better bike. I believe there was a step by step tutorial on how to do the 3x3 air box mod using parts out of a Dyno Jet jet kit. I did this mod but can’t remember all the specs as to where the needle clip is supposed to be for sea level. I’ve moved across the country to the west coast and am trying to make my bike run again. Any help would be much appreciated...

OP has an S model most likely with the Mikuni carb.  You've posted jetting for the FCR carb.

My fault. I saw the 3x3 mod and assumed it involved the FCR.
