2006 DR-Z 400 SM jetting options..

Recommended Posts

Hello guys... There is plenty information for DRZ and jetting options in here.. but I need to ask, since I haven't seen nobody with the same mods as I have...

The bike:

2006 DRZ 400 SM

the mods:

FMF PowerBomb exhaust header.. with a Remus exhaust pipe

Hi Flow air filter

3x3 air box mod

Intake and exhaust HOTCAMS (not in yet.. but it will be before jetting)

The thing is, I Bought those on the internet.. and done the 3x3 mod before getting the jet kit..

I am having plenty back fire.. since I put my Remus (even before making the 3x3 mod) ! it will only back fire on deceleration. But believe me it will scare the hell out off you!!! Not even WRC cars do that much backfiring!

Still, it's kind a nice when you get bored with the car in front off you!👍

However I need to get it fixed... And as far I can tell (following everybody's advice) , JD kit is the way to go..

Question:

is everything that I need in that kit?

Which needle settings should I go for?

Sorry My poor English.. I'm Portuguese..

BY THE WAYYY, SUMMER IS AROUND THE CORNER!! GOOD RIDING EVERYBODY!!🤣

the jd kit comes with what you need except for the US spec air jet.

you will need to remove and block the pair valve to stop the decel pop.
