HI,
Jets are removable orifices in the carburetor that come in multiple sizes, the bigger the hole the richer the mixture, there is also a needle that is tapered with slots in it. The top clip of the needle would put the needle into the jet the furthest, and the bottom clip the least, the furthest down would keep the needle furthest from the jest resulting in a richer mixture…
Plugs, we are referring to the spark plug, the metal/ceramic device located at the top of the cylinder with that thick wire that attaches to it and the ignition coil.

ok i thought that was the plug, but to jet do i have to mod the carb??? or what do i have to do???

is it ok to say.. let less oil in.. my problem is that i'm getting lots of spooge on the back of my pipe....

you have to disassemble the carburator , the jets usuall are threaded into the carb body, and unscrew out. I would suggest to locate some kind of doccumentation to view before attempting this blindly

i have looked at some docs, i just wanted to know some terms and stuff thanks... but do i have to mod the jets??

You don't modify the jet, you buy optional one in larger or smaller sizes and replace (unscrew and screw in) the current jet with them. To get a nice education on carburators, go to JustKDX.dirtrider.net in the first post of this forum. Click on Tech Tips, Click on Carb Tuning and read. It has pictures and everything (they even move!).

You can also go to Kawasaki.com, they have break-down pictures of virtually everything on the bike. might help you to see the assembly/disassembly order.

I wouldn't recommend modifying the jets just for the sake of doing it. Re-jetting is done to "tweak" the bike to your riding style, the terrain you ride in, and the climate, etc.

For example, if you are fouling plugs every time you ride, you probably need to "lean" the carb by moving the clip or re-jetting. On the other hand, if the bike is too lean you will need to make it richer to keep from ruining your motor.

If you ride with some experienced riders, let them watch you ride and have them look at your bike and advise you. Good Luck!

For leaning the carb, the first thing I would do is move the needle clip up one position (away from the pointed edge of the needle). Do this by unscrewing the top off of the carb. Next, depress the spring and remove the throttle cable from the cap. When the spring and cable is removed, remove the needle from the cap. There will be a small clip on the top of the needle and it will be in one of about 5 clip positions. Assuming you can move it up further away from the pointed tip of the needle and towards the actual cable, move it up one position and reassemble the spring and carb. Run the bike and inspect the plug after running it for a few minutes. If there is no room to move the clip up because the clip is already at the top position, you will need to re-jet the carb. In many cases, you can solve the problem simply by moving the clip on the needle. If it's still too rich and you have room, continue moving it up one position at a time and re-test it.

If you want the correct advice go to this site (http://justkdx.dirtrider.net/) and all shall become clear. It`s the best you can do for tips and tricks on everything KDX. Rock On Canadian Dave!

Go to this thread
http://dirtrider.net/forums3/showth...?threadid=62692

and then find canyncarvr's post (about the 12th one down). Click on the link to a discussion w/pictures by R. Rohrich.

Stole this from farmerj, it is a great couple of threads on reading plugs. Make sure you read everything about carb tuning in the CDave's site as suggested here, then make sure you read the threads above to really understand how to read a plug. I had it completely wrong before I read this. :thumb:

Or, just go here:

Same thing...a few less clicks.

'Course anyone can take the shortcut. ;) I just found such interesting stuff to look at along the way :thumb:
