What is the jetting setup? Numbers Please
This is the STOCK JETTING CONFIG:
220-42 Pilot, 1173 Needle, 145 or 148 Main
200- 48 Pilot, 1174 Needle, 160 Main
What u got??
This is Canadian Dave's Recommendations:

1995 to 2003 KDX200

Stock -Run the stock R1174K jet needle in the second from the top clip position, 45 pilot jet, 155 main jet and fine-tune the pilot circuit using the air screw.

With a performance pipe/expansion chamber, the air box lid removed and the stock or a performance silencer run a 42/45 pilot, R1174K jet needle in the mid clip position, a 152/155 main jet fine tune the pilot circuit using the air screw.

1997 to 2003 KDX220

Stock run a 42 pilot jet,the stock R1173L jet needle in the second from the top clip position, a 142/145 main jet and fine tune the pilot circuit using the air screw.

With a performance pipe/expansion chamber, air box mods , the factory or after-market silencer and the stock 33mm carburetor run a 42 pilot, the stock R1173L jet needle in the second from the top clip position, a 145/148 main jet and fine tune the pilot circuit using the air screw.

Same as above but with your carburetor bored between 35 and 36mm or running a 1988 to 2003 KDX200 35mm carb jet according to 95 to 2003 KDX200 requirements.

Addition of Boyesen reeds or a Boyesen RAD Valve will require you to lean the pilot and main jet one size and readjust your air screw.

my main jet is a 155 and my pilot is a 48, how is this right if i have a 220?

Either a 35mm carb, is installed, It's a 200 instead of a 220 and/or the jetting is off.
The pilot should be around a 45, 42 or maybe a 40.
First figure the above out first
Get the CARB ID #'s and look them up in the manual or post them

 

[kdx220freak]

ok i will go get them now

 

[kdx220freak]

the only numbers that i could find on the carb, were

PWK
V981 A015

thats all i found it was on the side, right above the bowl.

 

[Green Hornet]

Thats the 33mm(220)carb. Rejet to standard, then work on it

 

[KdxChode]

The one that came on my 220 says V981 AN16 on it. I can't believe Keihin doesn't give some way to ID them on the website.

 

[kdx220freak]

greenhornet, is there a way you know that is a kdx220 carb and not a kdx200 carb?? cause i measured it out to be 35mm but i cant see any evedence that it has been bored out.

 

[Green Hornet]

The carb number u provided is the same as my 33mm. My 35mm is V980. I was suspect if your carb was bored. I would believe a good "BORE JOB" ;) would be hard to tell

 

[kdx220freak]

wow this is hurting my head :bang: :bang:

 

[the trail rider]

why dont you just jet the 35mm for a 220 and call it good. it will run better and you will beat most other 220s but you will lose a little bit of low end.

 

[kdx220freak]

i guess, as long as i can still do wheelies in third or foruth

 

[Green Hornet]

If it was indeed BORED and you are sure it measured 35mm. Then leave the 155 alone for now and change that 48 pilot out to a 45 or 42, possibly a 40. I'm around 500ft above sea level and have mine set up as 40, 152 and the 1173 in the middle or 2nd from top. I posted the CD recommendations. So try those

 

[kdx220freak]

is there anyway i can tell if my carb has been bored out???
