DRZ jetting confusion

Recommended Posts

I installed the Big Gun exhaust system for the DRZ 400s ( mmm nice and loud ), BG suggested I use a 145MJ and .002 shim (slighty confused by the shiming part ) I also have done the 3x3 airbox deal. I was wondering what jetting I should use? What I have read is a DJ stage 2 would work but I havent done any cams so I :banghead: .

Thanks

your bike needs a dynojet stg1 kit for a S model.shimming the needle only fixes half of the stock lean needle.

As I understand the best way to get the best setting is to just play with the configurations until you get the best results. I read another user whom has done the same mods and had these settings " stock main, 4th needle clip, 25 pilot, and 2.5 turns on the fuel screw ". Any insight appreciated.

exactly,4th clip refers to the dj needle.
