DRZ400E 2001 - Rejet and Pipe = Idle Prob

I am the original owner of a 2001 DRZ400E (Non-Cali) with less than 100 miles on the bike and just did the below mods. The jet kit came from Factory Pro.

- Jardine Full Exhaust and Pipe

- Pilot Jet #48

- Jet Needle - 1070x-74mm3-ti @ #4 Pos

- Main Jet #145

- Main Air Jet #180

- Full Level 10mm+/-1mm

- Fuel Screw 3.5 turns out

- Removed the Coasting Enricher

- Snorkel is removed

- Ride at sea level (Southeast Texas)

The problem I am having is the bike will not maintain an idle even with the idle screw turned all the way up. I did put the Coasting Enricher back on the bike and it will now maintain an idle (idle adjustment about middle). It was my understanding by rejetting the carb I would be able to remove the Coasting Enricher. Did I do something wrong with my jetting combo? Any input?



you cant remove the coast enrichener unless you make the need changes to the pilot air circuit.

needs a 100 pilot air jet.


I really appreciate the info. This is my first time with an off-road machine, and my first "Hare Scramble" event is next weekend. I am trying to get everything in order. This really helps.
