Yet another please confirm my jetting thread

Recommended Posts

Hi Guys,

I did a bunch of research on here and here is what I cam up with:

My Bike:

2002 DRZ400S

400E FCR carb

400E airbox

400E cams

Yoshi TRC full Titanium exhaust

I will be riding between 2000-4000' elevation.

Carb settings:

160 Main Jet

200 Main Air Jet

EMN Needle 3rd clip position

45 Pilot Jet or 48?

100 Pilot Air Jet w/ coast enhancer removed or 60 with CE intact

2 turns on fuel screw will get the Keintech or Zip Ty, which one is better?

I will also be doing the Eddie Mod

A couple things I'm not sure about is the pilot and the coast enhancer. If it works, I would like to keep it. What's the opinion about this?

Also do I really need to order a jet kit or can I just get the jets I need?

Thanks Everyone!

Thanks for the info Eddie, you're the man.

Is the Keintech screw okay?

Does removing the CE have any negative effect?

I've had the Zip-Ty for over 10k. Seems ok. :banana: I remember there was some concern about it damaging the FCR, but then no worries.

any screw that isnt aluminum is fine.

if you remove the CE you may notice a little more pop on decel.

I was thinking aluminum seemed fragile for how tiny the tip is.

Anyone try the TM Designworks Titanium fuel screw? Will it fit the 400E slant body FCR?

The Stealth Racing fuel screw looks cool too, anyone use it?

Sorry to jump in but I just bought an 03 E with 3x3 and full exhaust and would like to know if the jet settings here are good for 600-900 feet elev. as well. I am currently running 160 main, 200 main air, stock needle on 5th clip. I think 48 Pilot and coast deleted. Not sure Does this sound right?
