rode bike and it really sputters at the bottom
do I richen bottom with jetting or with longer accell pump squirt. It is actually worse then before when when you crack the throtle and it dies
before bk mod if you were moving it wouldn't die
now it will.
this site is awesome!!!

We need a little more info on your bike....
Jetting?, pipe? I did the BK mod on my 01
wr426 as jetted as per James Dean's suggestions and what a difference!
Here's my specs:
Grey wire mod
YZ timing(might go back to WR)
48 pilot jet
obeln needle-went up to third pos.(a little boggy in #4 clip)
168 main jet
1 turn out on fuel screw
Bike now pulls my arms out of the sockets right of the bottom, with no hesitation or bog.
Only compaint I have is that I have to use the hot start when hot instead of a little kick.
Won't recommend any other advice for fear of a tongue lashing from Taffy.
Hope this Helps
Thanks to JD for his knowledge and others for
their expert advice. Hope to run into James sometime this year while riding and give him a big hug and then steal( I mean buy) a copy of his jetting manual

in my opinion these machines go from rich and running ok to a bit rich but spluttering to correct and obviously enough running awesome.
you're stuck in the middle.
i would try dropping the needle one clip and then try turning the PS in to 1.5 and then 1 turn and see which helps.
if either of these two has helped then you may trust me and buy a smaller PAJ and go from a #100 to the #75. if you already have a #75 then i would buy a 42PJ.
hope you got that.

How about a new needle?
It seems everyone likes and is using the EKN
what is your advice
and if I should go with the EKN what is yamahas Part#?

Big TIP: When working on the carb , disconnect the throttle cables at the grip first. Remove the Hot Start button (1 8mm bolt) then loosten the clamps on the rubber grommets on the carb. You can then rotate and slide the card out far enough to work on it comfortably. When reinstalling the carb, slide it back into its slot and pull up on the cables with your left hand while guiding the carb with your right hand. Works like a champ. Thanks to James Dean for that tip earlier this year.....Has saved me much aggrevation.
Also contact NHKEVIN about a Kouba Fuel Screw Adjustment tool.....Very Cool...and Great for on the fly adjustments.

the difference between your ELN and an EKN is guess what! a half a clip
so have a go at what i've offered.
jetting Q's is a great guide and if you have the time i would write out my settings on a sheet and note how i gradually leaned out the jetting from stinking rich (IMHO!!!!) to correct.
have you noticed how the DR boys run a #60 PAJ? here we are on ~100 and suzuki are on #60?????

In my owners manual it says I have a DRR
Part # 5gs-14916-rr is this the same needle you r talking about (ELN)?
Posted January 14, 2002 - 05:22 AM
you've got the worst needle ever invented.
yep get the EKN it's the business. if they're out you can get the EKM. if you're looking for wheelie popping torque you can try the DMM or DMN.
i'm selling Gus my DMM and it's better in tight corners, mud and shiert!
i had "unfinished business" and this is the needle i wish i'd carried on with.

I just busted a gut here with your "worst needle ever" comment. But at least we are on the same page.
you wouldn't know the part # for EKN?
or a place I could order one online?
Thanks for you help
