45 Pilot

200 Main air

60 Pilot air

OBDXP clip 5 "down from the top"

you're going to want to start with something like;

165 main jet

45 pilot jet

100 main air jet

emn needle

clip 3

9mm float level

about 2 turns fuel screw

also,you'll probably need the e model intake manifold boot and the e model throttle cables as the sm cables are too short to work right.the head stays will need to be moved to the left side for proper cable clearance.you'll need a vacuum nipple for the intake to run the stock petcock too.

i have the same carb on my 08 drz, 3x3 full yosh system 01 drz e carb that jetting is way lean. i run all the stock jetting and a 165 main jet. i moved the metering rod to clip 5, fuel screw at 2 turns out.bike hauls ass compared to stock. you will need all the things bumtarder recommended to install it on your bike. you will not be dissapointed.
